[BioC] limma read.maimages for scanarray express .csv files

[sltucker at artsci.wustl.edu]

I set my locale to "C", and now have a different error.

> RG<-read.maimages(files, source="scanarrayexpress", path=path,
columns=list(Rf="Ch1 Median", Rb="Ch1 B Median", Gf="Ch2 Median", Gb=
"Ch2 B Median"))
Error in `[.data.frame`(obj, , columns[[a]]) :
	undefined columns selected

My new sessionInfo() is

> sessionInfo()
R version 2.4.1 (2006-12-18)
i386-apple-darwin8.8.1

locale:
C/C/C/C/C/en_US.UTF-8

attached base packages:
[1] "stats"     "graphics"  "grDevices" "utils"     "datasets"  "methods" 
 "base"

other attached packages:
  gtools    limma
 "2.3.0" "2.9.17"

Thanks!
