[R] Possible memory leak in loop.
I was trying to use memory.size() to determine whether a code loop I am executing created a memory leak, since one replicate of the simulation takes 670.98 seconds according to proc.time(), while 5 replicates takes 170762 seconds. So I set it up as: memA - memory.size() looping code... memB - memory.size() memA returns as 9.3, and memB returns 11.3. I'm not familiar with fluctuation patterns in RAM usage (if there are any). Does anyone with more experience know if this is indicative of a memory leak? Thanks, Jon -- Jonathan P.

Or do we, what's the word... imbue it. - Jubal Early, Firefly [[alternative HTML version deleted]] __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
Re: [R] Possible memory leak in loop.
If you are running on Windows, you might want to use 'perfmon' to look at the memory usage of the process over time. You might also want to put calls to memory.size in your looping code to see if there are things you are doing in the code that might temporarily use a lot of space and maybe fragment memory.
