Hello,
If what you want is to combine the files into one data.frame then there
are 2 things you should see:
1) You create a variable named 'temp' and don't ever use it.
2) You never combine the data.frames you read in.
Try instead the following.
temp <- data.frame()
for(i in 1:22) {
infile<-paste("chr",i,"/Z-score.imputed",sep="")
psT<-read.table(infile,header=T,as.is=T,sep="\t")
temp <- rbind(temp, psT)
}
str(temp) # to see what you have
Hope this helps,
Rui Barradas

Hi all;
I have 22 directories named chr1, chr2,....,chr22. Each directory has a
file named "Z-score.imputed". I would like to combine Z-score.imputed
files into one. I wrote the following loop but did not get any results.
Your helps are highly appreciated.
regards,
Greg
temp<-c()
for(i in 1:22) {
infile<-paste("chr",i,"/Z-score.imputed",sep="")
psT<-read.table(as.character(infile),header=T,as.is=T,sep="\t")
ps<-psT[psT$Var>0.6,]
ratio=nrow(ps)/nrow(psT)
print(ratio)
}
