[R-gui] system() fails in JGR

[Ian Fellows]

Hi Liviu,

I can confirm the problem on windows and mac, though I don't have a
solution. At least in windows it might have something to do with the     

if (CharacterMode == RGui)

statement in sys-win32.c do_system function. But I'm not familiar enough
with the internals to solve this.

I'm forwarding this a mailing list that deals with java <-> R.


Cheers,
Ian

Dear all,
I initially sent this e-mail to r-help, with no luck, so I'm forwarding
here.

JGR seems unable to report the results of system() commands.
In a command-line R session:
> system("pwd")
/home/liviu
> system("acpitool")
 AC adapter     : on-line
 Thermal zone 1 : ok, 67 C
> system("asdf")
sh: asdf: command not found

In JGR:
> system("pwd")
> system("ls -F")
> system("acpitool")
> system("asdf")


Would this JGR, or my system configuration at fault?
Liviu
