...e/height at each point I would like to localise the peaks of that topological surface. Which R algorithm can perform this? I see it as a clustering problem where the peak should be at the center of each cluster.

Dear all, I wonder which R algorithm could perform a search of local maxima in an spatial grid, in other words, having the coordinates of a map (x,y,z... up to 6 coordinates) and then the altitude/height at each point (h) (in total 7 numerical variables) I would like to localise the peaks (local maxima) of that topological surface. Which R algorithm can perform this? Thanks a lot, Josep Maria,

...30) How to do that with ggplot2 and override it to the previous scores plot? with geom_segment apparently you can do that, but how? Anyone can give me a clue? Thanks in advance and congratulations for ggplot2! It is great!

R experts, I have three columns. c1 and c2 are numeric variables whereas c3 are the clusters classes (nominal variable, 10 different: cluster1, cluster2, cluster3, cluster4, cluster5 ....). I'd like to plot c1 against c2 (easy!) in a 2D plot and put different color depending to the cluster class automatically regardless the number of clusters. Could anyone give a hand?
