I will explain what R-bloggers is and then move to explain what I hope it will accomplish.R-Bloggers.com is a central hub of content collected from bloggers who write about R (in English) and if

Abstract Data Type Operations in R

This morning, I got a chance to read enough of the R Language Definition to finish my implementations of push and pop. While I was at it, I also wrote implementations of unshift, shift, queue and dequeue. Here they are:1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 push <- function(vector, item) { vector.lvalue.symbol <- substitute(vector) new.expression <- paste(vector.lvalue.symbol,

Wow, doesn't time fly! It's hard to believe that this blog is one year old already: our first post was on December 9, 2008. I remember when we first had the idea of doing a blog exclusively devoted to R that some wondered if there would be enough news about R to warrant daily updates, but with the community...

With no readily-available answer, John answered the question himself, by counting the number of times each function is called in all the...
