R 2.10 'memory leak'? on OS X

Thanks Duncan, I managed to get R to start through the terminal this way. Still no luck getting the R.app to start. Is it possible to directly access (and then trash or modify) the .RData and .RProfile files? I assume they would be recreated if I could then open the R.app. Having searched for them on spotlight and in the /user/library folder, I don't see them anywhere - are they always located in the same place on OS X?
.RProfile won't be recreated: it's where you put your own startup customizations. It sounds as though .RData is a more likely culprit. .RData is created when you quit and reply Yes to the question about saving. I forget if there are special rules on a Mac about where the saving occurs, but on other systems it's in the current working directory. On startup, R will look there and in the user's home directory. You probably want to ask on R-sig-mac for some Mac specific advice. Duncan Murdoch

Dear R users, I am running R 2.10.0 on OS X 10.5.8. I had been running 2.10 successfully for about a week (and have used previous R versions for 2+ years on the same computer) until 2 days ago it failed to start up for me. Now when I try to start R, the application tries to initiate for several minutes then crashes. Looking at the activity monitor, my memory usage goes from having about 1.6Gb free (out of 2Gb) to <7Mb in the first 10-15 seconds of attempting to start the program. At this point I either have to force quit R (as everything starts to freeze up) or wait several minutes for it to crash. I have erased the application and reinstalled it 4 times now - with exactly the same result. I looked around in the Library and System folders to see if any other files needed to be removed, but couldn't find any. I have also restarted the computer and repaired permissions multiple times - and then reinstalled R, with no luck. The exact same thing happens if I start R64. I did not updated OS X or R, or install any other programs, just prior to this first happening and am at a loss to explain what's going on. I have copied the first part of one of the crash logs below. Does anyone have any ideas for to remedy this?
It sounds like one of your user-specific startup files is causing the problem, e.g. .RData, or .Rprofile. Did you try starting R with option --vanilla? That will skip them. Duncan Murdoch
