Any ideas about better ways for solving such a problem than the one
described above?
Thanks.

Specifically, I have an S4 class, call it "foo", with a slot 'x'

patch for graphics/R/plot.R that fixes incorrect tick positions
...ago to avoid
conversion to double and thus dropping custom Axis methods. The patched
version was tested with custom time/date Axis methods and works fine, as
well as it works fine with POSIXct objects.

CTRL-C during .Call causes R to quit to command line
Hello,
During a .Call e.g
while(TRUE){
value <-rhsqnextKVR(rdr) ## has .Call in this function
if(is.null(value)) break;
}
if I press CTRL-C, R exits straight to the command line.
Q: How can I prevent this? I should point out that my library uses
JNI, so I'm not sure if that is causing it.
I'm using R-2.8 on Linux (RHEL 5)
Thank you in advance

Why no race condition when returning UNPROTECT-ed memory from C?
Consider the C (or C++) code called from the .Call interface:
SEXP foo() {
SEXP *p = PROTECT(allocVector(REALSXP, 10));
...
UNPROTECT(1);
return p;
}
Why is there no danger that the allocated memory will be garbage
collected after the UNPROTECT, but before the return of p?
I have used code like this for some time and have never had a
problem, but I'm not sure if/why it is guaranteed
