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.
This has nothing to do with it - use system(.., intern=TRUE) if you want R to capture the results. Otherwise the process output goes to stdout/stderr instead. Cheers, Simon
I'm forwarding this a mailing list that deals with java <-> R. Cheers, Ian -----Original Message----- From: r-sig-gui-bounces at stat.math.ethz.ch [mailto:r-sig-gui-bounces at stat.math.ethz.ch] On Behalf Of Liviu Andronic Sent: Thursday, March 19, 2009 1:29 AM To: R-SIG-GUI Mailing List Subject: [R-gui] system() fails in JGR 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 System info:
