Hi Kenny,
It's a bit hard to tell without seeing the data, but I think you may 
have the table in text form in the file, so you probably want something 
like:

for(i in 1:Number_files) {
  tabledata<-read.table(filelist[i])
  plot(tabledata,...)
}

But the reading in will depend upon what format the data are in the files.
