[R] signal to interrupt R evaluation

[Vadim Ogranovich]

Hi,

Sometimes I am unable to interrupt R evaluation by typing C-c C-c (I assume
there is something wrong with my ESS setup). So my question is which signal
can I send to R (UNIX) to interrupt execution of a top-level expression
(without killing the process)?

Another similar problem. Suppose I have a for loop with try() around the
body of the loop so that if the body fails the loop goes on to the next
iteration. Now again I want to interrupt execution of the loop as whole, not
just the current iteration. Is that doable?

Thanks, Vadim
