[Rd] parallel::detectCores(TRUE) gives: Error in system(cmd, TRUE) : error in running command

[Marius Hofert]

Hi,

Both under the current R-devel (r66456) and a version from about 3
months ago, I experience the following behavior:

> parallel::detectCores(TRUE)
Error in system(cmd, TRUE) : error in running command
> traceback()
3: system(cmd, TRUE)
2: gsub("^ +", "", system(cmd, TRUE)[1])
1: parallel::detectCores(TRUE)
>

This is on Ubuntu 14.04. Does anybody else see this? [I currently have
quite a heavy workload, otherwise I would have installed and tested it
also under 3.1.1]

Cheers,

Marius
