[R] setwd() command on windows vs. linux/unix

[William Dunlap]

You can get a more informative error message from system("bash -c 'cd
yourDirectory'"), although it will not take R to that directory if there
are no problems.  E.g.,  I did in a shell
  % mkdir -p dir/subdir
  % chmod -x dir
to make an untraversable directory 'dir' and a subdirectory of it.  Then in
R I get:
  > setwd("dir/subdir")
  Error in setwd("dir/subdir") : cannot change working directory
  > system("bash -c 'cd dir/subdir'")
  bash: line 0: cd: dir/subdir: Permission denied
And for a nonexistent directory I get:
  > setwd("no/such/directory")
  Error in setwd("no/such/directory") : cannot change working directory
  > system("bash -c 'cd no/such/directory'")
  bash: line 0: cd: no/such/directory: No such file or directory

(It would be nice if the name of the offending directory and a reason were
given in setwd's error message, but that would require someone to write the
code.)
