HI,All 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 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 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 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 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 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 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?
