Memory management
...say what are the memory limits of
R. Say, what's the max heap size for instance ????
Secondly, I invoke R with the following commands each time:
rgui --vsize 30M --nsize 1000K
rgui --vsize 30M --nsize 2000K
rgui --vsize 30M --nsize 3000K
rgui --vsize 30M --nsize 4000K
I try to open a matrix 8000x8000 by issuing
x<-matrix(nrow=8000,ncol=8000)
I always get the following message:
Error: heap memory (20480 Kb) exhausted [needed 250000 Kb more]
It's always 250000 Kb less. Although gc() reports the memory management
as
expected (correctly ?), increased every time I invoke R with greater...

Heap size
Hi,
I am trying to create a matrix 8000x8000 but cannot
make R work properly with:
rgui --vsize 30 --nsize 1000000
I can't pass an nsize value more than 1000000.
What are the limits uder windows 98 ?
Best,
Costas

outer(-x, x, pmin) cannot allocate
R> x <- 0. + 1:8000
R> y <- outer(-x, x, pmin)
Error: cannot allocate vector of size 1000000 Kb
Why does R need to allocate a gigabyte to create an 8000 x 8000 matrix?
It doesn't have any trouble with outer(-x, x, "+"). Thanks.
