Thanks for the reply,
maybe I shall say bumps
If you want to count the local maxima in the n x n matrix returned by
kde2d, AND you know there are no ties, you could do something like the
following:
> set.seed(1)
> x <- matrix(sample(10, 25, rep=TRUE), 5, 5)
> x
[,1] [,2] [,3] [,4] [,5]
[1,]3935 10
[2,]4 10
