Dear Barry, In general, I believe users are already accustomed with the classical arrows "->" and "<-" which are used as such in quoted expressions. But I agree that "-.>" is a very neat trick, thanks a lot. A small dot, what a difference.

Hi, I am planning on putting some R script in an appendix of a LaTex document. Can anyone recommend me a way of how to format it? Is there a way to keep all line breaks without having to insert \\ in every single line? Thank you! Benjamin

Hi all I use Sweave extensively to mix R and LaTeX, and often have R code appearing in my LaTeX document. Just a quick question then: What is the best way to add example of R commands into LaTeX in-line? (That is, not using Sweave.) For example, suppose I wish to place in my document this instruction: ...is done in R using the command \verb|lm( y ~ var.one + var.two )| as follows: I
