Hi Marna,
Assuming that you are descending into different subdirectories from

Maybe this assumption is not needed.
Since setwd returns the current directory, it is safer to assign that
value to a variable and in the end use it reset the original state.
directories<-c("dir1","dir2","dir3")
for(directory in directories) {
setwd(directory)
# do whatever you want to do
# then return to the directory above
setwd("..")
}
Using your code,
directories<-c("dir1","dir2","dir3")
for(directory in directories) {
old_dir <- setwd(directory)
# do whatever you want to do
# then return to the original directory
setwd(old_dir)
}
Hope this helps,

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

Hi R users,
I need to run a analysis using a data for each folder. I do have several
folders. Each folder contains several files but these files name are
similar to the files that is saved into another folders. I need to repeat
the analysis for every folder and would like to save the output in that
particular folder. After completing the analysis in one folder, I want to
move another folder. Basically I was doing manually (repeating the analysis
each and every folder manually). Is there any way to make a loop so that I
can run the analysis for different folders? Is there any example code?
Thanks for your help.

[R] repeating functions for different folders?
Hi R users, I need to run a analysis using a data for each folder. I do have several folders. Each folder contains several files but these files name are similar to the files that is saved into another folders. I need to repeat the analysis for every folder and would like to save the output in that particular folder. After completing the analysis in one folder, I want to move another folder. Basically I was doing manually (repeating the analysis each and every folder manually). Is there any way to make a loop so that I can run the analysis for different folders? Is there any example code? Thanks for your help.
