[BioC] set geneNames in exprSet object

[Marcelo Luiz de Laia]

Dear all,

I read a data set with the command:

 > Tol.eSet <- read.exprSet("Tolerante_b.txt") and the result is wonderful!
 > Tol.eSet
Expression Set (exprSet) with
        2516 genes
        18 samples
                 phenoData object with 1 variables and 18 cases
         varLabels
                sample: arbitrary numbering

Now, I try to set the geneNames slot. I try these commands:

 > Tol.geneNames <- read.table("geneNames.txt",header = TRUE,colClasses 
= "character")
 > Tol.eSet$geneNames<-Tol.geneNames
 > Tol.eSet$geneNames
NULL
 > geneNames(Tol.eSet)<-Tol.geneNames
Error in "rownames<-"(x, value) : length of dimnames [1] not equal to 
array extent

The column that contain geneNames is named Genes in txt archive.

Anyone could help me?

thanks

Marcelo
