Thank you for the quick reply.
It seems that Ctrl-C interrupts "pure" R functions (i.e. R scripts that do
not call external compiled libraries) but when I run functions that in turn
call external C code (such as gam() in the package mgcv), the Ctrl-C does
not appear to propagate that deeply, if I may use such loose language.
You are leaping to conclusions. Compiled code can arrange to be
interruptible or not, and that in R itself has made suitable arrangements.
Another issue to take up with the author of mgcv ....
The Stop icon in the R.app on MAC OS is similarly unresponsive when e.g.
gam() is performing some extensive computations.
(I am just using gam() as an example, nothing special about it, I think)
You are right, I should ask the author about the source code, I just did not
want to add more requests to his InBox.
Thanks again,
Markus

Dear fellow R users,
is there a generic way to gracefully interrupt an R
function without
terminating the entire session ? I am mainly
interested in this answer for
Linux and MacOS.
I found neither Esc nor Ctrl-C to work; it seems
that R does not check for
signals periodically?
Well, Ctrl-C works for me. Rather than check for signals, R installs
a signal handler and gets the OS to do the work.
On Mac OS it is unclear if you mean R or R.app. R.app has a Stop sign
icon, amongst other ways.
Also, an entirely unrelated question: I have been looking
unsuccessfully for
the R sources for the examples given in Simon Wood's book
on Generalized
Additive Models. I had hoped they would be part of the
mgcv package but they
are not.
Has anyone had any luck with this ?
Why not ask him directly?
Thanks,
Markus
