I use a Mac (10.4.11 Mac Os X).
In my .tcshrc I define an environmental variable MY.
Is it possible to find out its value from inside R? When one loads
R for Mac OS X Cocoa GUI written by:

Stefano M. Iacus
are files like .tcshrc read by R?
Can I make the value of this environmental variable available to R?
Did you try starting the R GUI from the command line whilst using tcsh?
<username>% /Applications/R.app/Contents/MacOS/R &
The R GUI when started by launch'ing it picks up different environment
vars than when starting it from a shell.
And Sys.getenv() would show them.
HTH,

p.s. R-sig-mac is a better place for this question.
Sys.getenv() produces a lot of output, with the values of many environmental
variables, but not this one.
Do I need a file with the correct value of MY, and have both R and my Unix
shell read the same file, or is there a better way to proceed? I want to
avoid duplicating the information in source files, as this can lead to a
setup that is very hard to maintain.
Thanks for any help.
David
