Hello, I am runnning ?a program on R with a "big" number of simulations and I am getting the following error: Error: no se puede ubicar un vector de tama?o ?443.3 Mb I don't understand why because when I check the memory status in my pc I get the following:
memory.size()
[1] 676.3
memory.size(T)
[1] 1124.69
memory.limit()
[1] 4000 which should in theory allow to have a vector of size 443.Mb. I am running it on a pc on windows, 4gb RAM and intel core i7 processor. Does anybody know what might be going on?
It is not that *a* vector of size 443 MB could not be allocated given your system. However, during your simulation, multiple objects take up memory, and that 443 MB vector was the final one that was too big to assign. Depending how your simulation is setup, you might be able to remove objects that are no longer needed or rewrite it to a less memory intensive form. I do not know enough about memory+R to offer any specific advice as to solutions. Hopefully someone else here can chime in. Good luck, Josh
