Are you using the 64 bit version of R ?

R version 2.13.1 (2011-07-08)

I think that I may actually be running out of RAM, but I am not sure why. If I keep an eye on the resource monitor, I see that I am maxing out, so process must be consuming much more RAM than the reported half GB. I will have to try on a bigger computer or find a way to reduce RAM use. Thanks,

I did get it to work, but it took all 12 GB of RAM that I had available. lpc uses ALOT of memory, and is a bit messy. I was maxed out until I ran gc() garbage cleanup. The actual CAMERA object is only 203 MB. If my dataset was any bigger, I don't think I could have made this work.
