Hello everyone

I would like to use the pvac package to analyze data from Affymetrix HuGene 1.0 ST arrays. However, I keep getting this error when running the code:

> raw <- ReadAffy(celfile.path="CELS")
> library(pvac)
> ft <- pvacFilter(raw)
Making absent/present calls, preprocessing data ... 
Error in FUN(1:18[[1L]], ...) :

       as.character(pns), as.integer(length(mms[, x])), as.double(tau), 
       as.double(sat), dpval = double(length(unique.pns)), length(unique.pns), 
       PACKAGE = "affy")
7: FUN(1:18[[1L]], ...)
6: lapply(X = X, FUN = FUN, ...)
5: sapply(1:length(pms[1, ]), function(x) {
       .C("DetectionPValue", as.double(pms[, x]), as.double(mms[, 
           x]), as.character(pns), as.integer(length(mms[, x])), 
           as.double(tau), as.double(sat), dpval = double(length(unique.pns)), 
           length(unique.pns), PACKAGE = "affy")$dpval
   })
