## now I want to do kmeans of all possible variable pairs, e.g. v1 and v3
## automization in a second step later
wjk <- kmeans(tmat[,c(1,3)], centers=centroids[c(1,3),], iter.max=10,
algorithm="MacQueen") ## obviously wrong

kmeans Clustering
...ds, iter.max=10, algorithm="MacQueen")
P <- rbind(P, pj[[i]]$cluster)
}
P <- P[-1,]
## gives a matrix of partitions using each single variable
## (I'm sure, P can be programmed much easier)
## 3. kmeans using all possible pairs of variables, here just e.g. variables 1
and 3:
wjk <- kmeans(tmat[,c(1,3)], centers=centroids, iter.max=10, algorithm="MacQueen")

which, of course, gives an error message since "centroids" is not a matrix of
the cluster centers. How on earth do I correctly construct a matrix of centers
corresponding to the pairwise va...

[PATCH 0/9] tools: remove or disable old/useless/unused/unmainted stuff
depends on "autoconf: regenerate configure scripts with 4.4 version"
This series removes some of the really old deadwood from the tools build
and makes some other things which are on their way out configurable at
build time with a default depending on how far down the slope I judge
them to be.
