[BioC] affycomp and info.txt? --> method.name and .data.frame

[Mohammad Esad-Djou]

Thanks for your help.

I produced info.txt: (e.g.)

fullname: Rafael A. Irizarry
method: MAS 5.0
nickname: MAS 5.0
competition: YES
URL: http://www.affymetrix.com/support/technical/technotes/statistical_algorithms_technote.pdf

> affycomp.info <- read.table("H:/Profile/Eigene Dateien/Dip_bak/Pr_sprach/R/info/info.txt",sep="\t",as.is=TRUE,quote="")
is Ok...
I control affycomp.info:

> affycomp.info
                                                                                              V1
1                                                                   fullname: Rafael A. Irizarry
2                                                                                method: MAS 5.0
3                                                                              nickname: MAS 5.0
4                                                                               competition: YES
5 URL: http://www.affymetrix.com/support/technical/technotes/statistical_algorithms_technote.pdf

afterwards:

> method.name <- affycomp.info[3,2]
Error in "[.data.frame"(affycomp.info, 3, 2) : 
        undefined columns selected


where does error lie?

Thnaks,
