Many thanks for your help. I will consider the processx package. Best regards Nicolas

Does the batch file contain an explicit "exit" to ensure that cmd.exe terminates? > system(nmrun, invisible = F, show.output.on.console = T, wait = T) With wait = TRUE, it should be possible to interrupt the process by pressing Ctrl+C in the cmd.exe window, but R itself will not be running your commands until system() returns (or is interrupted, terminating the process). You can specify a timeout for a foreground process using the 'timeout' argument of the system() function.
