[R] R 2.10 'memory leak'? on OS X

[Stropharia]

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?

thanks,

Steve
