Problem with .C
Hi, As other have said, it's very difficult to help you without an example + code to know what you are talking about. That having been said, it seems as if you are just getting your feet wet in this R <--> C bridge, and I'd recommend you checkout the "Rcpp" and "inline" package to help make your life a lot easier ... -steve On Tue, Oct 4, 2011 at 8:04 AM, Grigory Alexandrovich

Hello,
I wrote a function in C, which works fine if called from the main-function
in C.
But as soon as I try to call this function from R like .C('foo',
as.double(x), as.integer(y)), the programm crashes.
I created a dll with the cmd command R --arch x64 CMD SHLIB foo.c and loaded
it into R with dyn.load().
What can be the cause of such behaviour?
Again, the C-funcion itself works, but not if called from R.
Thanks
