Question

[Shamim Sarhadi]

I am so sorry for my non-specific question

when I open my R it gives me an error that says :

Error: cannot allocate vector of size 64.1 Mb
In addition: Warning messages:
1: Reached total allocation of 6029Mb: see help(memory.size) 
2: Reached total allocation of 6029Mb: see help(memory.size) 
3: Reached total allocation of 6029Mb: see help(memory.size)

Also my saved object does not exist anymore? I run this code memory.limit(size=15000) , but it can not be saved

Thanks in advance

Your saved object might be the problem. Check your current directory for a .RData file: ls -a .RData. It looks like you saved a really large object and R is automatically loading it when you start the interpreter, running out of memory.

[Shamim Sarhadi]

yes, I saved a large data,I found my files in cache folder! is there any way to fix this problem or at least to prevent R for loading previous workspace automatically ??

[Matt Shirley]

Try R --vanilla: https://stat.ethz.ch/R-manual/R-devel/library/base/html/Startup.html
