Apologies in advance if I've misunderstood something or this is a stupid question. When using the R on my Mac (2.4.1 and 2.3.0), if I exit and ask to save the workspace, .RData is updated but .Rhistory is not. Introduction to R makes it sound like both should be saved, and it clearly happened for me at some point in the past: I have some (very old) commands in my .Rhistory, and these are loaded at startup, but new entries are not added. Is this a bug, or am I doing something wrong?? Much thanks, Ian
