Dear all, I have the following problem: I am using Windows XP as OS and have a R program which uses optim() in a loop. Although I overwrite every variable in the loop the memory R is using is increasing until my system breaks down because the swap file is getting just to big. I suspect that optim() is creating some variables which are not deleted automatically. So I tried to do the following: every 10th loop or so, I save the variables I want to keep, delete the memory with rm(list=ls(all=TRUE)), and load back the data I saved before. But this is also not working. rm(list=ls(all=TRUE)) does not delete everything (I can see in the Task Manager of Windows that the memory occupied by the Rgui process stays huge).
Does anybody had similar problems and/or know how to solve it. Thanks in advance for your help.
