You are on a 64-bit architecture and the C interface is declared as void mapthin(x, y, n, delta, symmetric) double *x, *y, *delta; long *n, *symmetric;
R's integer type is int, not long, but they are the same on a 32-bit platform. I am pretty sure that changing long to int will fix this. There are a few other quirks, and I would check some of the other uses of `long' in the C sources. On Thu, 1 Jul 2004, Kevin Bartz wrote: > Hi everyone!
