Do you mean that you have one file where the data is ordered by group? If so, using scan and a loop is an easy option. If you have the data in separate files by group, just make a character vector with your filenames as elements and use a loop to read the data using read.table at each iteration. Or if they all have similar names such as group1.txt, group2.txt, etc. you could construct the filenames on the fly using paste. HTH, Simon.
Hello
Instead of reading in group1.txt I want to read in groups1 for the
first iteration of i, then groups2 for the second and so on.
Obviously I can't use groups(i) but assume there is a way to do this.
group<-read.table("C:/Data/April 2005/group1.txt",header=T)
thanks in advance
Meredith
