[Bioc-devel] read.maimages, limma

Hi everyone,

I am using R.2.1.0 with limma 1.8.18 to read a "quantarray" .txt file.
 > RG <- read.maimages(file,source="quantarray")
Error in "[.data.frame"(obj, , columns$Rf) :
         undefined columns selected

The same data with the previous version of R (2.0.1) was working fine.
Does anyone have a suggestion?

Laurentiu
