I am using R 1.9.1 under Windows XP Professional. Is there any R function that returns the filesystem path from which the global environment (workspace) was loaded (and to which it will, by default, be saved)? This seems identical with the current directory, so in any given session it is not too difficult to find out by other means. But for several reasons I would like to find this out from within R. Thanks. -- Michael Prager, Ph.D. Population Dynamics Team, NMFS SE Fisheries Science Center NOAA Center for Coastal Fisheries and Habitat Research Beaufort, North Carolina 28516 http://shrimp.ccfhrb.noaa.gov/~mprager/

My thanks to Sundar Dorai-Raj, Rolf Turner, and Chuck Cleland for supplying the answer within minutes of my query. (I had tried pwd(), cwd(), and so on, and tried looking in the help. It *can* be hard to find things sometimes....) Mike

Appendix B of the Intro manual describes the startup sequence. .RData generally comes from the current directory, but that's not necessarily the same at the time you test as it was when R started.
