Is there a function similar to C's usleep in R?
from the man pages:
The usleep() function will cause the calling thread to be suspended from
execution until either the number of real-time microseconds specified by
the argument useconds has elapsed or a signal is delivered to the
calling thread and its action is to invoke a signal-catching function or
to terminate the process. The
suspension time may be longer than requested due to the scheduling of
other activity by the system.
I do not want to dyn.load usleep for portability reasons. Calling sth.
like a system("sleep 1")
is not an option.
