[Bioc-devel] minimizing copies when creating ExpressionSet
my bad... after creating either y1 or y1, resident memory used is rouhgly 10GB (i'm counting here the 'x' object too, so i think about 7GB is used to create either object). my question is if there's something i'm missing that would minimize the use of these 7gb.... sorry for the typo and possibly not making myself clear. b

Hi,
given the following:
library(Biobase)
x = matrix(pi, nr=6.5e6, nc=70) ##3.4GB
y1 = new("ExpressionSet", exprs=x)
y2 = new("ExpressionSet", assayData=assayDataNew("environment",
exprs=x))
Is there any obvious way of reducing the memory footprint when
creating y1 and/or y2? With y1, it takes me around 18GB RAM... with
y2, around 10GB. Is there anything else I can do from my end to
minimize this?
Thanks a lot,
