Thanks Marc. The information is in help(Memory-limits).
We are aware that at some point we will need to raise this limit and have
discussed ways to do so. But it is not going to be an issue for a while:
working with 16Gb objects needs the sort of amount of memory that will not
become common
Thanks for the clarification, Marc. Also, I should correct my error below. I
wrote excel's limit is 16^2. But, it is 2^16 -1

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!

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

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
Harold,
Actually there is a maximum size, even if one had sufficient memory.
Since a matrix is a vector with a dim attribute, and these objects are
indexed using integers, the maximum sized vector one 'could' create is:
.Machine$integer.max
[1] 2147483647
which is:
2^31 - 1
[1] 2147483647
