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
Grigory Alexandrovich
