+1--this is the single most-annoying issue with R that I know of.
My usual solution, after accomplishing nothing as R spins idly for a couple
hours, is to kill the process and lose any un-saved work. save.history() is
my friend, but is a big delay when you work with big data sets as I do, so I
don't run it after every command.
I have cc'd r-help here, however, because I experience this problem with
non-OSX R as well...when I run it in Linux or from the OSX command-line (I
compile R for Darwin without aqua/R-framework), the same thing happens.
Is there some way around this? Is this a known problem?
Google searching suggests no solution, timeline, or anything, but the
problem has been annoying users for at least twelve years:
