Dear Rusers, The error for the following was that it cannot allocate the vector of length 1920165909. a <- expand.grid(se1=0:100/100, sp1=0:100/100, se2=0:100/100, sp2=0:100/100, DR=0:100/100) How to solve it? Maybe setwd(dir) can, i am not very sure about it. Any ideas about it? [[alternative HTML version deleted]]
What are you trying to do? The expand.grid will create an object with 10 billion rows with 5 variables. My guess is that you would need 50G * 8 bytes/word = 400GB just to hold the one object. How much memory do you have on your system? Is there some other approach you can use? You may have problems since I think an object can only have 2^31 values and your would have quite a bit more. I would suggest that you rethink your problem that you are trying to solve.

Out of memory? How large is your physical memory?

Dear Rusers,
The error for the following was that it cannot allocate the vector of
length 1920165909.
a <- expand.grid(se1=0:100/100, sp1=0:100/100, se2=0:100/100, sp2=0:100/100,
DR=0:100/100)
How to solve it? Maybe setwd(dir) can, i am not very sure about it.
Any ideas about it?
