Cluster and plot smooth effects

This layers clusters several smooth effects and plots the cluster centers.

l_clusterLine(centers, cluFun = kmeans, a.clu = list(), ...)

Arguments

centers	the number of clusters. This is the same a the `centers` argument in stats::kmeans.
cluFun	the function used for clustering. I must take (at least) arguments `x`, `centers` and `data`, which have the same interpretation as in stats::kmeans (which is the default).
a.clu	list of further argument to be passed to `cluFun`.
...	graphical arguments to be passed to `ggplot2::geom_line`.
