[R] showing available environment variables

2006-11-29 Thread Karin Lagesen

I have searched through the mailing lists and the docs, and I seem
completely unable to find a way to make R list all available
environment variables that it uses.

The reason that I want to do this is the following:

The default program for reading files when using openVignettes on my
system is ggv. ggv is broken. I would therefore like to use a
different program, and I found the variable R_PDFVIEWER which should
do the trick. However, so far no luck.

Therefore, how do I ask R what variables are available, and how do I
get it to show what it is currently set to.

Thanks!

These retrieve and set environment variables:

?Sys.getenv
?Sys.putenv

In this specific case you need to look at the R-admin manual for what 
various variables do, and Sys.getenv(R_PDFVIEWER) or Sys.getenv() for 
the current value or list of values.

R_PDFVIEWER is set in R_HOME/etc/Renviron, and you can override the 
setting via ~/.Renviron (see ?Startup).

Try options(pdfviewer=something)
