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. Just on start up. For no
apparent reason. Then it would release memory and fall back down to 50-60MB.
Upon opening any window to edit old files or
start a new one, the race would come back. programs that used to execute in
short periods would take forever. Often not completing after hours.
So:
1. did did a MAC system update ( Leopard)
2. installed R 2.12
3. X11 gets clobbered so I had to reinstall that.
4. RGDAL had to be reinstalled but I was able to make that work after some
time.
Now raster programs that worked an hour ago are broken and I found out that
ncdf is not available yet.
What's the simplest way to revert to R 2.11 and diagnose the memory race I
seem to be having.
