I have a continuous loop running in an external library that I am calling from C (R API). This loop is processing events in real time with the possibility of significant lag between events. When processing an event, I can make use of R_CheckUserInterrupt, but while the external library code is waiting on a new event, I don't have an opportunity to call this - my entry points are only on

...code differ based on preprocessing directive HAVE_AQUA, which could explain why Spencer observes a different behavior than Peter and Berend (all on macOS). Whenever the R_CheckUserInterrupt() function is called it in turn always calls R_ProcessEvents(). At the end, there is a code snippet - if (R_interrupts_pending) onintr(); - which is Windows specific and could be another important difference between Windows and Unix. This function is defined in: * src/main/errors.c (https://github.com/wch/r-source/blob/trunk/src/main/errors.c#L114-L134) The do_setTimeLimit() function controls global variables cpuLimitV...

Hi, one thing I haven't been able to figure out from R-exts is how to interrupt a calculation running inside an embedded R. C code inside R calls R_CheckUserInterrupt() intermittently to check for interrupts, but how does my GUI tell R that the user wants it interrupted? -Deepayan

list(...), I am looking for a way to interrupt R from a callback: specifically, to interrupt plotting (typically on a cairoDevice, but would be good if it worked with other devices too). Of course, one can interrupt R nicely from the console with Ctrl-C (or Esc in Rgui), but I need to do it from a GUI. Callbacks run in a new thread, so obviously stop() etc will not work. I tried to look into how

setTimeLimit(elapsed=1) causes a timeout error whenever a call takes more than one second. For instance, this is how it works on Windows (R 3.3.1): > setTimeLimit(elapsed=1) > Sys.sleep(10); message("done") Error in Sys.sleep(10) : reached elapsed time limit Also, the error propagates immediately and causes an interrupt after ~1 second; > system.time({ Sys.sleep(10);
