@halirutan yes, they are certainly the same person. In fact if you look at Sjoerd's answer, subbu has even replied to a comment under niren's account. I don't think it particularly matters if users have multiple accounts, since clearly in this case it isn't an attempt to circumvent a suspension or something like that.
@drN this policy really seems silly to me. If they are offering a trial, why not have it fully functional so that people can evaluate it properly? It's hardly as if someone who plans to use it only once is going to buy it anyway (or if they do they'll probably ask for a refund soon afterwards) so I don't see how they lose anything by having the trial version able to save or print. In fact I would think that this approach is likely to lose them more potential customers than the alternative.

International Workers' Day
International Workers' Day (also known as May Day) is a celebration of the international labour movement. May 1 is a national holiday in more than 80 countries and celebrated unofficially in many other countries. History International Workers' Day is the commemoration of the 1886 Haymarket affair in Chicago. The police were trying to disperse a public assembly during a general strike for the eight-hour workday, when an unidentified person threw a bomb at them. The police reacted by firing on the workers, killing four demonstrators. "Reliable witnesses testified that all the pistol fl...

@Ghersic See if this site works: filedropper.com

@Here we go, sorry for the delay.
I uploaded a .zip containing the notebook, the excel file I imported the data from, and the .mx file I load to, I think it's called, "reload the kernel state" so that the definitions I've created are still usable upon re-loading it.
@Mr.Wizard In case it's important, I used ExcelLink to import the data from the excel file, and that is where the first few lines of code come from. However, if you use the DumpGet command and point it towards the .mx file I uploaded it should redefine the "data" term as the table I'm hoping to manipulate.

Well here's a laugh for you: my old tools are making this difficult. You see, .mx file are platform dependent so I cannot use that, and I'm afraid version 7 doesn't like XLSX files very much. Is it possible for you to save that file as an old-school .xls file and upload again? (Sorry.)

P.S. - I hope you don't laugh too much that each drug
drug's dataset consists of four measurements ranging from 5m to 24h. My background is in physics which makes this seem a little short on data, but the people I'm working for are biochemists... ;).
@Mr.
@Mr.Wizard Also, only the first four points are crucial to what I'm trying to do at this point, the latter 4 after the one "Empty" cell in each list are the respective standard deviations, and are less important.
 
Mr.Wizard
Mr.Wizard
@Ghersic I've looked over your Notebook and you are doing what I thought you might be, and yes, it's inefficient. There are several ways to approach this, and it partly depends on how you want to handle (work with; access) the data. Do you wish to reference each record by name, e.g. "AP6_173" or do you usually expect to operate on all (or thirds) of the list at the same time?
 
Ghersic
Ghersic
Usually I'll be operating on thirds at a time or less (that is, larger fractions than a third at a time), only needing to specify each dataset (drug's) at the start (first column) of the table when I'm graphically representing the data.
oops, each drug's name, that is
 
Mr.Wizard
Mr.Wizard
(Sorry for being slow to respond; I'm easily distracted.)
 
Ghersic
Ghersic
5:31 PM
That's ok, I am too, and the time you're saving me from the inefficiency of my current notebook surely has us net positive! :)
 
Mr.Wizard
Mr.Wizard
But when you are graphing the data, you wish to manually specify a series of drug names?
 
Ghersic
Ghersic
Yes, Legending is an ongoing process, but at the bottom of the notebook I have a sample of one of the graphs made from 1/3 of the 26 different datasets.
Only in displaying which line is which dataset will I be trying to manually reference each drug name (or so I thought).
Ack, pay no mind to the faulty FirstDrugsLegend entry above the ListLogLinearPlot.
 
Mr.Wizard
Mr.Wizard
(Sorry, be right back; phone call)
 
Ghersic
Ghersic
No problem, take your time.
 
Mr.Wizard
Mr.Wizard
@Ghersic I did not understand the answer so I'll ask again as this is fairly important: right now in the graph (ListLogLinearPlot) you have only FirstDrugs, and earlier when you list the drug names in AllDrugsList you list (naturally) all the drug names in order. If you do not need (frequently) access the drug data in random order by name, but would instead like to reference "all drugs" or "first third" and let the program do the rest... (continued)
... I may use a different data format than if you expect to do something like myPlot[{"drug3", "drug17", "drug9", "drug14"}, (* options *)] (a customized plot function by drug name).
I hope my question is making sense. :-)
 
Ghersic
Ghersic
5:44 PM
I think it does. As long as I can Legend the drugs relatively easily, which I think is accomplishable regardless probably, I'm alright with simply letting the program do each for me on the level of individual drugs. (The first of the two above posts says ... (continued) but I don't see a way to expand it, so I may be missing a detail here)
 
Mr.Wizard
Mr.Wizard
I typed (continued) manually just so you'd know there was more coming; the chat software said my message was too long.
 
Ghersic
Ghersic
Ohh, alright!
My entire setup, really, is subject to change at this point. The setup you described in generating {{"cat", {5, 8}, {10, 18}, {20, 9}, {1440, 1}},
{"dog", {5, 19}, {10, 15}, {20, 15}, {1440, 7}}, ...} in your answer seemed perfect.
Your answer to my question, here that is:

http://mathematica.stackexchange.com/questions/24242/efficient-data-entry-manipulation-with-many-datasets
 
Mr.Wizard
Mr.Wizard
Tell you what, I'll show you both formats if we have time. Let me start more conceptually.
Though I know it includes parts that you didn't ask to focus on, there are several places in the Notebook where you start operating on each part of the list (each drug data record) manually, e.g.: 
AP6156z = Take[AP6156, 4 ;; 4];
AP6157z = Take[AP6157, 4 ;; 4];
AP6158z = Take[AP6158, 4 ;; 4];
AP6159z = Take[AP6159, 4 ;; 4];
AP6160z = Take[AP6160, 4 ;; 4];
AP6161z = Take[AP6161, 4 ;; 4];
etc.
 
Ghersic
Ghersic
That sounds great. If there's a way to provide reputation or "upvotes" for you I certainly would.
The "z" entry was in transit to extract the point at which I would insert a text legend (hopefully using epilog) as it was the only way I knew how to go about that.
 
Mr.Wizard
Mr.Wizard
Anytime you find yourself writing code like this it should be a flag that you're working too hard. :-) This would be true for any high-level programming, really, but Mathematica in particular is well set up to operate or lists, arrays, and tensors.
 
Ghersic
Ghersic
5:51 PM
Alright thank you, I'm glad to hear that and thought Mathematica was known for it's efficiency.
 
Mr.Wizard
Mr.Wizard
Also, every expression in Mathematica is a data tree of sorts, which you can graphically represent on screen with TreeForm.
There are a number of tools for operating across the parts of rectangular arrays, and also for manipulating expression trees.

@Mr.Wizard Hi!

belisarius
6:01 PM
@Mr.Wizard yep you're right
 
Mr.Wizard
Mr.Wizard
Anyway, let me get back to @Ghersic before I completely forget what I'm doing. :^)
@Ghersic let me give you a simplified conceptual example of what you are doing, and how you might do it differently. 
a = {1, 2, 3};
b = {4, 5, 6};
c = {7, 8, 9};
a2 = a[[2]];
b2 = b[[2]];
c2 = c[[2]];
 
belisarius
belisarius
@Mr.Wizard In any case, the equations are different (but very similar). Enough said about that :D
 
Mr.Wizard
Mr.Wizard
^This is what you have. Manual repetition of the same operation on multiple objects.
Instead, you might write this: 
abc = {{1, 2, 3}, {4, 5, 6}, {7, 8, 9}};
abc2 = #[[2]] & /@ abc;
the content (value) of abc2 is {2, 5, 8}
This is done by creating a "pure function" (look up Function in the docs) with a single parameter represented by # (short from of Slot[1] -- look up Slot).
 
Ghersic
Ghersic
Kk.
 
Mr.Wizard
Mr.Wizard
This is then "mapped" across the list abc (an array is just a list of lists in Mathematica) using the function Map, which has the short notation /@.
A simpler example is: f /@ {1, 2, 3}
 
Ghersic
Ghersic
6:07 PM
Yes that was my next question.
 
Mr.Wizard
Mr.Wizard
@belisarius Not yet, my friend. :^)
 
Ghersic
Ghersic
hehe
 
Mr.Wizard
Mr.Wizard
Also, please understand that these operations are not limited to lists (that is, expressions with head List when displayed with FullForm, and typically entered with {}), but can apply to other expressions. Here is another example: f /@ ("q" + "r" + "s") which yields f["q"] + f["r"] + f["s"]
Other function names for you to look up later are Apply, Table, and Scan.
 
Ghersic
Ghersic
I will.
 
Mr.Wizard
Mr.Wizard
Now, as @belisarius pointed out above (now removed) there can be even better ways to perform such operations. In this particular case (the abc array) you could use abc2 = abc[[All, 2]], which will typically be much faster than mapping, when it is applicable. You could also Transpose as he did, and then use Part.
 
Ghersic
Ghersic
6:13 PM
That makes sense, my previous attempt included Tranpose and Part.
 
Mr.Wizard
Mr.Wizard
Likewise, there are internal functions that have the attribute Listable, which automatically apply themselves across lists, e.g. Plus, allowing: abc + 5 to yield {{6, 7, 8}, {9, 10, 11}, {12, 13, 14}}. I am however getting off topic now.
 
Ghersic
Ghersic
ahh yes
That is good to know.
At a previous point in data analysis I have to subtract the average background fluorescence of the samples, the 'Plus' and 'Listable' functions seem like they would be good for this.
 
belisarius
belisarius
@Ghersic Are you manipulating images?
there are a lot of specialized functions for that
 
Mr.Wizard
Mr.Wizard
Indeed. Now, returning to your Notebook, with the data we can do this: 
Part[data, 2 ;;, 1 ;; 5]
 
Ghersic
Ghersic
Only datasets for now, in the hopes I might ListLogLinearPlot a large number of relatively small datasets.
 
Mr.Wizard

{{"AP6_156", 28.5708, 32.0251, 37.5862, 66.8786}, {"AP6_157", 78.3041, 82.9332, 87.6697,
96.6977}, {"AP6_158", 13.3031, 14.4117, 16.9699, 37.382}, . . . }
 
Ghersic
Ghersic
Yes.
 
Mr.Wizard
Mr.Wizard
You can see that we are able to combine Part and Rest operations, and also process the data all at once.
Now, for the data format I wish to introduce another concept: replacement rules. You can create a list of rules (look up Rule) like this: 
rules = {"one" -> {5, 2, 1}, "two" -> {7, 6}, "three" -> {0, 19, 4}};
Using "two" /. rules recalls {7, 6}. The operator /. is short for ReplaceAll.
This allows you to easily access a record by name.
To convert your data I will use a named auxiliary function (like the one in my earlier answer), but it could be done using "pure functions" as shown above with #[[2]] &.
 
Ghersic
Ghersic
Sorry, what is the significance of the {7, 6} specifically? Are those positions in the list? This answer may be in Rule documentation, I suppose.
for rule "two", that is
 
Mr.Wizard
Mr.Wizard
6:24 PM
Ah, sorry. {7, 6} is arbitrary data belonging to the name "two". It doesn't need to be a list.
 
Ghersic
Ghersic
Ah alright that is much easier. Thanks
 
Mr.Wizard
Mr.Wizard
The point is that by using this format we can easily recall individual data records.
 
Ghersic
Ghersic
ok
 
Mr.Wizard
Mr.Wizard
By the way, pardon me if I hit you with too many new concepts; I'm not very good at separating these things and tend to use them all at once. :-)
 
Ghersic
Ghersic
thats ok, I think I follow so far
 
Mr.Wizard
Mr.Wizard
6:28 PM
Alright, consider this: 
recordToRule[{name_String, data__}] := name -> Transpose[{{5, 10, 20, 1440}, {data}}]
This code uses SetDelayed (short form :=) to create a new function named recordToRule.
The pattern on the left-hand side: {name_String, data__} matches the individual records output by Part[data, 2 ;;, 1 ;; 5] as described above, and does destructuring (bookmark for later).
The object name_String is a pattern (look up Pattern) named name, that needs to have the head String (which strings implicitly do). This is part of a list { } which literally matches the list in the record.
There remains the pattern data__ -- this is a pattern named data which matches any remaining sequence of arguments (elements) in the list.
You will need to look up Blank and BlankSequence in the help for examples.
Incidentally, replacement rules can use the same patterns.
what this function does when applied to the expression {"ghersic", 1, 2, 3, 4} is to match the parts described by the patterns, and substitute them into the expression on the right-hand side of the definition, e.g. "ghersic" -> Transpose[{{5, 10, 20, 1440}, {1, 2, 3, 4}}]
 
Ghersic
Ghersic
_String signifies that this specific pattern, name, is being created into a time-series representation
think I understand so far. Will look up these links.
yes.
 
Mr.Wizard
Mr.Wizard
@Ghersic Wait, I don't know what you mean. _String signifies a pattern that matches "a string" but not aSymbol or 3.14. Is that understood?
 
Ghersic
Ghersic
I'm not sure I said that right, but your subsequent comment confirmed what I was at least trying to say I think.
ahh ok
 
Mr.Wizard
Mr.Wizard
Great. Understand that the pattern names such as data are localized to the SetDelayed definition. For example data in recordToRule has no relation to the table which you named data in the Notebook. This concept of localization is important, and it is important to understand when it is and is not being applied. For example, definitions made with Set (=) do not localize.
Putting this together we have: 
ruleData = recordToRule /@ Part[data, 2 ;;, 1 ;; 5];
 
Ghersic
Ghersic
so here I would say `recordToFule[{AP6156_String, data__}] := AP6156 -> Transpose[{times}, {data}}]

Gotcha
Ah alright.
 
Mr.Wizard
Mr.Wizard
6:41 PM
ruleData should now look like this: 
{"AP6_156" -> {{5, 28.5708}, {10, 32.0251}, {20, 37.5862}, {1440, 66.8786}},
 "AP6_157" -> {{5, 78.3041}, {10, 82.9332}, {20, 87.6697}, {1440, 96.6977}},
 "AP6_158" -> {{5, 13.3031}, {10, 14.4117}, {20, 16.9699}, {1440, 37.382}}, . . .
 
Ghersic
Ghersic
yes yes yes. this is getting exciting.
 
Mr.Wizard
Mr.Wizard
You can now do several different things with this. You can get a list of names: 
names = First /@ ruleData
You can get just the data: 
dataonly = Last /@ ruleData
You can access specific records by name: 
{"AP6_168", "AP6_159", "AP6_178"} /. ruleData
@Ghersic I'm glad. Please take a few minutes to experiment with this. I'll then answer any questions about these specific methods, and then I'll need to leave for the day. We can continue tomorrow.

Ahh ok thank you, I've been taking snippets using snipping tools to reference our conversation, haha.
It seems to give errors at the ruleData = recordToRule /@ Part[data, 2 ;;, 1 ;; 5]; phase of permutation of each drug is longer than the dimensions {1, 4} of the list. hrm...

@Ghersic what do you get form Part[data, 2 ;;, 1 ;; 5] by itself? Any errors?

Doesn't seem to be, simply each drug name followed by its four values, identical to the permutation that {y1, y2, y3, y4} that the error shows.

I don't have much more time to debug this, but are you using this definition verbatim?: 
recordToRule[{name_String, data__}] := name -> Transpose[{{5, 10, 20, 1440}, {data}}]
(Also, try ClearAll[recordToRule] before running that.)

Aha, it worked! Some typo of mine, surely. Thank you very much, Mr. Wizard. That was some kicking of knowledge, I appreciate it.

Wolfram Blog: After 100 Years, Ramanujan Gap Filled
posted on May 01, 2013 by Oleg Marichev

A century ago, Srinivasa Ramanujan and G. H. Hardy started a famous correspondence about mathematics so amazing that Hardy described it as “scarcely possible to believe.” On May 1, 1913, Ramanujan was given a permanent position at the University of Cambridge. Five years and a day later, he became a Fellow of the Royal Society, [...]
