Extracting coordinates for cluster::clusplot()
2 messages · Michael Kubovy, Mark Difford
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. Mark Difford.
