[R-SIG-Mac] Naive question about permissions

[Paul Hewson]

Thanks very much all, I'm still sure this is mac naivety on my part, but I'm still curious how I've managed to foul up what seems like such a simple procedure.


John's longer point - I'm going to check out removing and re-installing.   I had to enter a system password and checkbox that I wanted all users to be able to use R.   I can certainly use R GUI as myself so don't entirely understand how I gave R gui different ownerships/permissions that R console.

Regarding the other questions (my naive and presumably wrong thought was that I need to put myself as a user in group admin, but I'm not sure that's entirely correct).


John's question
R.home() gives
"/Library/Frameworks/R.framework/Resources"
Checking permissions gives 
pm6-0068:~ phewson$ ls -l /Library/Frameworks/R.framework
total 40
lrwxr-xr-x  1 root  admin   24 18 Oct 11:16 Headers -> Versions/Current/Headers
lrwxr-xr-x  1 root  admin   30 18 Oct 11:16 Libraries -> Versions/Current/Resources/lib
lrwxr-xr-x  1 root  admin   31 18 Oct 11:16 PrivateHeaders -> Versions/Current/PrivateHeaders
lrwxr-xr-x  1 root  admin   18 18 Oct 11:16 R -> Versions/Current/R
lrwxr-xr-x  1 root  admin   26 18 Oct 11:16 Resources -> Versions/Current/Resources
drwxrwxr-x  5 root  admin  170 18 Oct 21:22 Versions


Simon's question, yes typing R in the console gives me a the dialog box, but the console does also gives me the following:
/usr/bin/R: line 259: /Library/Frameworks/R.framework/Resources/bin/exec/x86_64/R: Permission denied
/usr/bin/R: line 259: /Library/Frameworks/R.framework/Resources/bin/exec/x86_64/R: Undefined error: 
(same for R vanilla)

Davor's question yields:

Can you show us the output of running:
ls -l /Library/Frameworks/R.framework/Resources/bin
