R.app not handling events

Caution: External email.


Aloha.

I don't have an answer but more info, perhaps.

I experience a similar condition with Rstudio in which I can't interrupt a data-intensive command (seems) that goes off into never-never land without terminating the entire Rsession.  This often means a lot of time wasted to get back to where I was.

If my memory serves, I used to experience what you see in the base R environment which is partly why I started using Rstudio; since it seems to happen less often there.  Ironically, now when Rstudio is 'hung', I start up base R and use it until Rstudio comes back or I give up and kill it.

I'm willing to run tests if there is something useful to do.

Every now and then R.app stops responding to various events while a long-running command is executing.  I can't scroll the console to look at earlier results, and I don't see partial results until the whole computation is complete.  If I ask MacOS to switch to that window, it won't come to the top (though clicking on it does bring it up, but I need to be able to see part of it to do that).

Once it finishes it returns to the console prompt and things look fine, but the same thing happens during the next long-running command.

This happens every now and then, but I haven't spotted the cause.  The only solution I've found is to quit the session and restart it.

Does anyone know what might be causing this, or a way to fix it without ending the session?
