system - Kill a calculation programme after user defined time in R -

say executable c:\my irectory\myfile.exe , r script calls on executeable system(myfile.exe)

the r script gives parameters executable programme uses them numerical calculations. ouput of executable, r script tests whether parameters ore not. if not good, parameters changed , executable rerun updated parameters.

now, executable carries out mathematical calculations , solutions may converge wish able kill executable once has takes long carry out calculations (say 5 seconds)

how do time dependant kill?

ps: question little related one: (time non dependant kill) how run executable file , later kill or terminate same process r in windows

you can add code r function issued executable call:

settimelimit(elapse=5, trans=t)

this kill calling function, returning control parent environment (which function well). use examples in question linked further work.

alternatively, set loop examines sys.time , if expected update parameter set has not taken place after 5 seconds, break loop , issue system kill command terminate myfile.exe .
