[R] repeating functions for different folders?

[Jim Lemon]

Hi Marna,
Assuming that you are descending into different subdirectories from
the same directory:

directories<-c("dir1","dir2","dir3")
for(directory in directories) {
 setwd(directory)
 # do whatever you want to do
 # then return to the directory above
 setwd("..")
}

This will allow you to start and finish in the same directory.

Jim
