\title{Trigger Event Handling}
\description{
R front ends like the Windows GUI handle key presses and mouse clicks
through \dQuote{events} generated by the OS. These are processed
automatically by R at intervals during computations, but in some cases
it may be desirable to trigger immediate event handling.  The
\code{process.events} function does that.
}
\usage{
process.events()
}
\details{
This is a simple wrapper for the C API function
\code{R_ProcessEvents}.  As such, it is possible that it will not
return if the user has signalled to interrupt the calculation.
}
\value{
\code{NULL} is returned invisibly.
