Trigger event handling

Description Usage Details Value Author(s) See Also


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 function does that.




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.


NULL is returned invisibly.
