@ChristophHanck I do read r-bloggers semi-regularly, but I don't get notifications via email

@Silverfish yes, I'm very happy that you had brought this up here as it turned out to be a very nice question and I really enjoyed the answer by @NickCox

It was a fun question; thanks to @Silverfish for asking and to those who liked the answers

@schvost probably (see what i did there?). ask your question on the main site

@ChristophHanck like R-bloggers?
