process.events: Trigger event handling
Description
R front ends like the Windows GUI handle key presses and mouse clicks
through 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
process.events function does that.Value
NULL is returned invisibly.
Details
This is a simple wrapper for the C API function
R_ProcessEvents. As such, it is possible that it will not
return if the user has signalled to interrupt the calculation.See Also
