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!
