Once again wondering why Mma doesn't have a built-in currying operator. Like Curry = Function[{f, a}, f[a, ##] &]...
Of course that example shows that it wouldn't probably be any shorter than writing function directly, but it might be more clear what's going on.

OlegYesterday I asked my first question on mathematica.stackexchange, but being as an unregistered user at that moment. Then I confirmed my email and would like to express my gratitude and note the correct answer, but it seems that following the link from my email I have created a new account and s...

@kirma I've never been happy with any implementation of Curry that I've seen.
When I first started, the Mathematica Cookbook had one.
I think the answer lies somewhere between two facts. Functions in the wolfram language are strange and not actually functions. Most customers couldn't use it.
V10 introduced a lot of curried forms for functions. Many of them weren't possible because of the ambiguity it would create in syntax.
I think that people who really want curry are like me when I started. I came from a background programming R and Ocaml mostly. I was writing code like Mathematica was an actual functional programming language.

@Szabolcs
g = Graph[{1, 2, 3, 4}, {1 <-> 2, 2 <-> 3, 3 <-> 1, 3 <-> 4},
EdgeCapacity -> {0.4, 0.6, 0.9, 0.7},
VertexLabels -> "Name"]; SetProperty[g,
EdgeLabels ->
MapThread[Rule, {EdgeList[g], PropertyValue[g, EdgeCapacity]}]]
FindMinimumCostFlow[g, 1, 3]
FindMinimumCostFlow[g, 1, 3, "FlowGraph"]
FindMinimumCostFlow[g, 1, 3, "FlowMatrix"] // MatrixForm
Can you help to understand this?
It should be 0.4*2+0.9=1.7?

@Searke Well, I think WR has lots of features it could omit, and currying could be one of those, implemented. But sure, it's not actually required for anything.

How can I extract data from this picture?

http://i.imgur.com/iY362Js.png

The caption of the picture reads: " Two-dimensional histogram values measured . Tick labels on the color bar are bin counts (17 force bins, 32 lifetime
bins, and n = 803 observations)"
I divided the image into two parts: 1st the main graph and 2nd the legend. I am trying to extract average pixel in the each block but I am not able to do so becuase the edges between the boxes are not well defined... so, I am trying to define the edges, which is kinda hard to do accurately
