Dear Friends,
How can I extract the coordinates used in the plot?
They are not made available. You can get them as follows:
x - rbind(cbind(rnorm(10, 0, 0.5), rnorm(10, 0, 0.5)),
cbind(rnorm(15, 5, 0.5), rnorm(15, 5, 0.5)))
pp - pam(x, 2)
## The coordinates are in obj$scores
princomp(pp$data, scores = TRUE, cor = ncol(pp$data) != 2)$scores
plot(princomp(pp$data, scores = TRUE, cor = ncol(pp$data) != 2)$scores)
I have not set the y-scaling to match to output from plot(pp, which = 1),
but you can set it for yourself to see that they are the same. Or you can
debug clusplot() for yourself.

How can I extract the coordinates used in the plot?
