looping problem

Hi Rui;

Is there any way to insert the chr ids in numeric as 1,2......,22 in the
final output. Here is output from str(temp). So I need also chr ids in a
column.
1          rs58108140 10583 G A -0.070438 0.059903
2         rs189107123 10611 C G -0.044916 0.085853

Regards,
Greg

    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 <http://as.is>=T,sep="\t")
         temp <- rbind(temp, psT)
    }

    str(temp)  # to see what you have

    Hope this helps,

        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
        <http://as.is>=T,sep="\t")
        ps<-psT[psT$Var>0.6,]
        ratio=nrow(ps)/nrow(psT)
        print(ratio)
        }
