I then merely open a document, an existing script, memory usage jumps to 500mb. I then select a couple lines to copy. Memory runs past 1gb and the system freezes for minutes at a time. Then magically the memory drops back down to 50 mb.

My other issue is that a library I depend on "ncdf" worked under R.2.11 but it's absent now and it looks like the upgrade to that package isnt on cran for the Mac anymore. > > Hope that helps, > -steve > > btw - I don't think "MAC" needs to be capitalized ... it's not an acronym > ;-) > > On Fri, Nov 12, 2010 at 3:50 PM, steven mosher <mosherste...@gmail.com> > wrote: > > I recently noticed that R was having memory "race" condition on my MAC. > At > > start up it would race to 1.3GB of memory used.
