After memory.limit(1500), the error message still pop out:
Error: cannot allocate vector of size 11529 Kb
While
memory.size()
[1] 307446696
memory.limit()
[1] 1572864000
And the system is only using 723MB physical memory, while 2G is the total.
Does anyone have a clue of what is going on?

Could anyone advise me how to allocate 1.5Gbyte memory for R on a Dell laptop running XP professional with 2G memory?
See ?Memory or the the R for Windows FAQ, which tells you:
"2.7 There seems to be a limit on the memory it uses!
Indeed there is. It is set by the command-line flag --max-mem-size (see How do I install R for Windows?) and defaults to the smaller of the amount of physical RAM in the machine and 1Gb. [...]"
I have tried
"C:\Program Files\R\rw1081\bin\Rgui.exe" --max-vsize=1400M
but I only get only 500MB for R actually.
I also tried memory.limit(2^30) in R and got error of:
Well, you don't want to allocate 2^30 *Mega*Bytes (see ?memory.limit),
do you?
Either use the command line flag --max-mem-size=1500M or within R: memory.limit(1500)
Error in memory.size(size) : cannot decrease memory limit
Since your limit was roughly 10^6-times off the right one, you got an integer overflow internally, I think.
