Question

I understand that in R to set my working directory I can do:

setwd("~/dir1/dir2/mydir")

If mydir is a unique directory name, is there way to specify the working directory without stating dir1/dir2 ?

Thanks

Sys.glob does what you want:

setwd(Sys.glob("~/*/*/mydir"))

If you don’t know how deep it’s nested, you can use list.files or dir:

list.files(path="~", pattern="mydir", all.files=TRUE, full.names=TRUE,
  recursive=TRUE, ignore.case=FALSE, include.dirs=TRUE)
