R help - Jun 2007 - What is the maximum size of a matrix?

hi, Rers

I tried to find out the max size (# of rows, # of
columns) of a matrix that is allowed by R but failed.

Can anybody let me know?

Thanks!
Guanrao

There is no maximum size. This will be driven by (at least) two issues.
First, how much memory you have on your own computer and second what
data you have in each cell. For instance, an integer takes less memory
than a floating point.

Other spreadsheet programs like excel limit the number of rows to 16^2
irrespective of memory, but that is not true here.

AFAIK, it only depends on how much free memory you have.
