Hello everyone. How are you all doing?
My name is Desiree. I'm a 1st grad student experiencing problems
reading 27
CEL files into R using the ReadAffy command. The total size of these
files
are 350 Mb. Here are my commands:
> library(affy) # loads the "Affy" package
> library(limma) # loads the "Limma" package
> setwd("path directory to the CEL files")
>mydata<-ReadAffy( ) # reads all of the CEL files in my work directory
But after I run the last command, I get the following error message:
Error: cannot allocate vector of size 279.1 Mb
In addition: Warning messages:
1: In `rownames<-`(`*tmp*`, value = c("1", "2", "3", "4", "5", "6", :
Reached total allocation of 1535Mb: see help(memory.size)
2: In `rownames<-`(`*tmp*`, value = c("1", "2", "3", "4", "5", "6", :
Reached total allocation of 1535Mb: see help(memory.size)
3: In `rownames<-`(`*tmp*`, value = c("1", "2", "3", "4", "5", "6", :
Reached total allocation of 1535Mb: see help(memory.size)
4: In `rownames<-`(`*tmp*`, value = c("1", "2", "3", "4", "5", "6", :
Reached total allocation of 1535Mb: see help(memory.size)
I've done it before on the same computer (specs: Lenovo Think with
Intel
Core 2 Quad CPU Q9400 @2.66GHz, 3.00 of RAM, Microsoft Windows XP
Professional Version 2002).
I've read previous posts and I will admit that the solutions offered
are
very hard for me to understand (I am a beginner). I have tried using
the
"memory.limit(size=3000)" command and then run the "ReadAffy()"
command
again but I still get the same error message. Any suggestions would be
greatly appreciated.
