Got it working with a package called 'xlsReadWritePro' (which requires a license after 30 day's...) This is my code: setwd("J:/Stage/Datasets2/Datasets/outData")

masterTable<-read.table("AR1000900A_N_241110_(Mapping250K_Nsp)_2,Mapping250K_Nsp,CNprobes.tab
_SNP_IDs.xls",sep="\t", dec=",", fill=T, header=T)
masterTable<-data.frame(masterTable)

fileNames<-list.files(getwd(), pattern='_0,5 -0,51.xls') library(xlsReadWritePro)
regionMatchM<-data.frame()
write.xls(regionMatchM, file= "Array012345.xls") for(i in 1:5) {

                fileName <- fileNames[i]
    newFile <- file.path(getwd(), paste(fileNames[i], "samen_0,5 -0,51.xls"))

                snpidFile<-read.table(fileNames[i],sep="\t", dec=",", fill=T, header=T)     snpidFile<-data.frame(snpidFile)

                regionMatch<-cbind(masterTable, snpidFile[match(masterTable$Pos, snpidFile$Pos),])

    regionMatchABCDE<-data.frame(regionMatch[10:18])     write.xls(regionMatchABCDE, file= "Array012345.xls", naStrings = "NAN", append=T, from= c(1,(1+i)*9), rowNames=FALSE) }
genomeInfo<-read.xls("Array012345.xls")
len<-length(genomeInfo[1,])
finalTable<-data.frame(masterTable, genomeInfo[,18:len]) summary(finalTable)
write.table(finalTable, file= "Array012345_final1.xls", append=F, col.names=T, row.names=F, quote=F, sep = "\t")

Thanks for the help anyway. If someone has a solution for this problem, without the need of a package, please reply
