Hi, All:

Is there anybody have problem running limma 2.2.4 from R 2.2.0 on Linux? I can run the same code for Limma 2.2.4 from R2.2.0 on windows without any problem. The following is information for R  and limma on linux:

> version
         _
platform i686-pc-linux-gnu
arch     i686
os       linux-gnu
system   i686, linux-gnu
status
major    2
minor    2.0
year     2005
month    10
day      06
svn rev  35749
language R

limma        "limma"        "/usr/local/R/lib/R/library" "2.4.4"

And the following is the error message from the command:
> library(limma)
> files <- dir(pattern=".gpr")
> RG <- read.maimages(files, columns=list(R="F532 Mean", G="F635 Mean", Rb="B532 Median", Gb="B635 Median"), wt.fun=wtflags(0.1))
Error in switch(source2, quantarray = { : Cannot find column heading in image output file
In addition: Warning message:
input string 32 is invalid in this locale in: grep(pattern, x, ignore.case, extended, value, fixed, useBytes)

I highly appreciate any comments and suggestions for this error.
