Dear All, at the moment I am using R for calculations of large databases. Unfortunately, R only manages to complete certain operations at some times, and not at others. I usually get the error message "cannot allocate vector of size XX"
I am using the 64-bit version with Windows 7. While my computer has 8 RAM, I do have a feeling that R cannot use all of it.
Searching online, I found that you can increase the memory with the options --max-mem-size/ --max-ppsize or change the environment variable R_MAX_MEM_SIZE to "allow deep recursion or large and complicated calculations to be done"
Unfortunately, I am not very knowledgable yet on how to use R and I did not quite manage to use the commands successfully. Could you please tell me whether these do make sense for my case and if so how (and at what stage of the process) I can use them?
Are you sure you're using the 64 bit R executable which comes with the R installation?
