Dear all,

I have the following problem:

  - I have written a program in R which runs out of physical memory  
on my MacBook Pro with 1.5 GB RAM

  - The memory usage is much higher then I would expect from the  
actual data in my global environment

  - When I save the workspace, quit R, restart R and load the  
workspace again, memory usage is much less then before
    (~50 MB instead of ~1.5 GB), although nothing seems to be missing.

  - It doesn't seem to be possible to reduce the amount of memory  
used by calling gc()

  - the behavior is independent of if I use R in command line or from  
GUI, so I can exclude a problem of the Mac GUI

Any suggestions what the problem might be or how I could debug this?

Thanks in advance for any help.

Best regards,
Klaus
