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: Simon Urbanek Stefano M. Iacus are files like .tcshrc read by R?
Can I make the value of this environmental variable available to R? 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.
