Hi Philip,
I think a bit more clarification may be useful yet!
1: How are you sending the command from R to Linux?
2: What is the command intended to be (as seen by Linux)?
And from what source (quasi-command line; script file; ...)
would it be read by Linux?
For example, on my Linux machine, I just did (in a shell
command line):
[EMAIL PROTECTED]:~$ touch "New Mexico"
[EMAIL PROTECTED]:~$ ls -l "New Mexico"
-rw-r--r-- 1 ted ted 0 2008-07-03 10:58 New Mexico
and then, in R, I did:
> system("ls -l \"New Mexico\"")
-rw-r--r-- 1 ted ted 0 2008-07-03 10:58 New Mexico
so I don't seem to have had the problem you describe below.
On the other hand, back in Linux, if I do:
[EMAIL PROTECTED]:~$ ls -l \"New Mexico\"
ls: "New: No such file or directory
ls: Mexico": No such file or directory
which looks like the problem you describe -- so clearly the
command did not get through in that form from R using the
command system("ls -l \"New Mexico\"").
Best wishes,
Ted.
