I have a script that runs correctly (no errors) on Windows, the first command is a "setwd(.....windows directory)"I installed the script on a Linux machine and changed the windows directory reference to the correct directory on the linux machine.when I ran the script I got a message that "cannot change working directory".?I confirmed I have read and write access to the directory.I mainly run R on windows infrequently use linux/unix and would appreciate suggestions.thanks in advance?Chris Barker, Ph.D. Adjunct Associate Professor of Biostatistics - UIC-SPH [[alternative HTML version deleted]]

Try 'choose.dir()' to see if you can navigate to the given directory, or take baby steps by doing one directory at a time.

That message comes out when the chdir() function (C library routine) returns any kind of error.? Because you said that have read & write access (you should also have execute in most cases), then the only return which makes sense is ENAMETOOLONG (although it could also be ENOMEM).

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.)
