I sent this to Bioconductor, but I think it is more of an R listserv
question, because of memory allocation trouble
I am having trouble getting the function heatmap() to work on the following
gene expression
> dim(SAMPLES_log)
[1] 12626 20
sample1 sample2...................sample20
gen1
gen2
gen3
....
gen12626
I have converted SAMPLES_log to a numeric matrix using:
as.matrix(SAMPLES_log)
when I use the following command:
heatmap(SAMPLES_log)
Error: cannot allocate vector of size 622668 Kb
In addition: Warning messages:
1: Reached total allocation of 1022Mb: see help(memory.size)
2: Reached total allocation of 1022Mb: see help(memory.size)
Is there some library in BioConductor that will allow me to output a
heatmap. I want to compare the expression of the first 10 samples with the
last 10 samples.
I have tried running that command in a Linux environment, also with no
success
thank you,
