[R] Is there a function for finding local extrema.

[Witold Eryk Wolski]

I have a vector with about 100.000 values representing a quite regular 
function (sinusoid like).
I would like to find all local maxima of this function (should be about 
4000). Is there a native routine for R?
Thanks in advance
Eryk.
