[BioC] reading data into limma

[Straubhaar, Juerg]

Hi,

 

I am using two-colour spotted array data which I downloaded from the
Stanford Microarray Database generated with GenePix 4000B. To read the
data I use:

 

 RG<-read.maimages(files, source="genepix", path=".", columns=colList,
fill=TRUE)

 

colList is a list of name=value pairs, specifying the forground and
background intensity columns for the two channels.

 

This generates an error:

 

Error in "[<-"(*tmp*, , i, value = NULL) : 

        number of items to replace is not a multiple of replacement
length.

 

Thank you,

 

Juerg Straubhaar
