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.

Usage

process.events()

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.

Value

NULL is returned invisibly.
