error in R

Question

[zizigolu]

Hello,

I was normalizing my array, I entered so and got error like below. What is the reason please?

library (affy)
..
data <- ReadAffy()
Error: cannot allocate vector of size 709.2 Mb

It's a memory allocation issue (is not specific of the affy package).

You can find some info on this Stack Overflow threads:
