I have two source packages, one normal and another a Tcl/Tk UI for controlling the former. However, as all UI arguments are passed to a single (potentially VERY long-running) function in the normal package, all output shows up after the completion of that function. I have a sort-of workaround for updating progress on UI during this, but one issue remains consistent. Early in the process, the normal package displays a graph so the user can determine whether it is worthwhile to continue. Problem is that the plot window shows up onscreen (empty) but never fills until the everything is done, defeating its purpose; I need a means of flushing pending R graphic events.
While trying to figure out how to fix this, I have noticed that executing the browser() method allows the plot window to fill prior to completion of the rest of the routine. Is there some means of triggering a pause in R execution that can be immediately resumed? Assuming browser() as a candidate, I would like to invoke it, then immediately continue (without user interaction being required to type 'cont'). I had hoped to use 'browser(expr=FALSE)' but that doesn't seem to help. Any ideas appreciated. ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
