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.

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,
