R Help

R is a free software very similar to S-PLUS and it can be downloaded from where you also find the wonderful quickly responding mailingslist r-help.

At the Centre for Mathematical Sciences, R is available on all Sun Solaris and Suse Linux machines by typing

 % R

at the prompt. Old (and new versions) of R can explicitly be accessed by Rnnn where nnn is the version number without dots, e.g. R181 for R v1.8.1 and so on.

How do I print from R?

After you have created a plot you have to save it to file and from there print it. Example

  dev.print(postscript, file="/tmp/")
  system("lpr -Pps3 /tmp/")           # Call lpr from within R

How to autosave the command history

To save the command-line history automatically when exiting R just add the following in your ~/.Rprofile file:

.Last <- function() {


Sweave is a really great tool, which allows you to incorporate executable R code within for instance LaTeX documents. First Sweave() is called on your R-LaTeX hybrid document, the R code is extracted and evaluated. Figures that are generated are saved as EPS and PDF files, necessary LaTeX code to incorporate the figures in the LaTeX document is inserted in place. The final result is a LaTeX document (together with figure files), which can be compiled as usual. How does it work? See help(Sweave) in the tools package.

One common problem is that people encounter is that the Sweave.sty file is missing. It is located at ${RHOME}/share/texmf/Sweave.sty; just save it in the same directory as your LaTeX document.
