CPU usage while running R code
I am currently running an R program on a computer with 16 Gb memory (Windows7, 64 bit). When I look at the task manager, I see that only 4 out of the 8 CPUs are being used. Is this due to some missing in the R code, or should I change something to the settings of the computer?

Error in memory.size(size) when calling R in batch mode (but not in interactive mode)
...a garbage collection, after two or three iterations, R crashes when used interactively. I thought that running and exiting R after each iteration would be the only effective way to "clean up" memory. If you have any other solutions, I would be happy to hear about them as well.

I have re-installed today the most recent version of Rtools.
Does anyone have an idea what is going wrong here?

R/C++ interfaces: crashes when using .c(), followed by correct results when R restarted
...ons of the dll, "is.loaded("equil_distC")" would still lead to a TRUE.
I would like to understand the structural reason for these problems. Again, the problem is not the C++ code - it does run correctly now, although it had crashed in the previous run.
Best regards

Error: could not find function
...the following error message:
Error: could not find function "BPGC"
When I defined "BPGC" in "calibrateCES", the problem disappears, but this is definitely not the solution I want, because I want "BPGC" to be available for other functions as well.
