[R] numerical differentiation

I would like like to compute first and second derivative
from numerical data. I hoped I could compute a spline
object from the data (that works), and then compute the
derivative from that spline objects, but I couldn't find
anything like that.

Does somebody know how to get numerical derivatives?
