But parallel::detectCores(TRUE) is a call of desparation: this ran
code intended for FreeBSD.
If all else fails read the help:
It has methods to do so for Linux, OS X, FreeBSD, Solaris, Irix
and Windows. ‘detectCores(TRUE)’ could be tried on other
Unix-alike systems.

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])

The same is true in R-2.14.1 on Ubuntu 12.04.4 LTS . Put a trace on
system with
trace(system, quote(print(command)))
parallel::detectCores(TRUE)
and you will see the offending shell command.

There is no /usr/sbin/sysctl on my Ubuntu 12.04 machine. There is a
/sbin/sysctl, but it does not accept the '-n hw.ncpu' arguments. Its
/usr/bin/nproc [-all] will tell the number of available [installed]
processing units and 'cat /proc/cpuinfo | grep processor | wc -l' will
also give the number

Thanks, Bill. The output is:
trace(system, quote(print(command)))
parallel::detectCores(TRUE)
Tracing function system in package base
[1] system
Tracing system(cmd, TRUE) on entry
[1] /usr/sbin/sysctl -n hw.ncpu 2/dev/null
