I was doing PCA (principal component analysis) with a DNA 
expression matrix (7000 rows/38 columns; from golubEsets) but I 
had the following problem

"Error:cannot allocate vector of size 397051 Kb
In addition: Warning message:
Reached total allocation of 119Mb: see help(memory.size)" 

I've already done some filtering (reduced to 3051 rows) but the 
problem remains, only the size of the vector to allocate is 

Can I allocate more memory? How? Probably the problem is also 
from the machine itself, which is a Pentium III 700 Mhz 128Mb 
RAM. Could you help me?
