I'm working on the next iteration of coxme. (Rather slowly during the summer). This is the most subtle code I've done in S, both mathematically and technically, and seems a perfect vehicle for the "literate programming" paradym of Knuth. The Sweave project is pointed at S output however, not source code. I would appreciate any pointers to an noweb type client that was R-aware. Other suggestions are welcome as well. At the end of the day I'd like to have a good user guide, technical reference, and solid enou...

In general, however, should I be using some other paradym for this "map to unique" operation? For example match(as.character(x), unique(as.character(x)) ? Terry T

Hi: For those of you who are adept at both SAS and R, I have the following questions: a) What are some reasons / tasks for which you would use R over SAS and vice versa? b) What are some things for which R is a must have that SAS cannot fulfill the requirements? I am on the ramp up on both of them. The general feeling that I am getting by following this group is that R updates to the product are

Context: R version 2.7.1 (2008-06-23) I don't know when this was upgraded in the department, I just ran into the aberrent behavior today. Problem: Our group BY CHOICE does not change character variables into factors by default. I can get into a long arguement as to why later, and will give one example of why below. The default behavior of S, Splus and R has been to create
