\description{
There is a command \command{shutdown} in both Windows and
Linux, and this function uses it to shut down a computer.

After the time \code{wait} has passed, R will execute
\command{shutdown -s -t 0} (for Windows) or
\command{shutdown -h now} to shut down the computer.

This function is a modified version of Yihui's shutdown
function from the {fun} package.

\examples{
\dontrun{
## when your code is extremely time-consuming,
# you may need this function;
# e.g. you wish to go to sleep, while keeping R running long computation...

os.shutdown()
## the next day you wake up, "thank you, R" :)
