HI,

I am trying to create a heatmap with 24 samples with 15672 varibles, I read
in the table in R, and then made it as a matrix, then try to create the
heatmap using heatmap(x,...)

However, I received the error message as:
> heatmap(t(x))
Error: cannot allocate vector of size 936.8 Mb
R(2925,0xa0b16500) malloc: *** mmap(size=982261760) failed (error code=12)
*** error: can't allocate region
*** set a breakpoint in malloc_error_break to debug

It seems like I do not have enough memory, how can I set a breakpoint as
suggested?

Thanks,

Meng
