How to use 'prcomp' with CLUSPLOT?
Hello,
I have a large data set that has more columns than rows (sample data below). I am trying to perform a partitioning cluster analysis and then plot that using pca. I have tried using CLUSPLOT(), but that only allows for 'princomp' where I need 'prcomp' as I do not want to reduce my columns. Is there a way to edit the CLUSPLOT() code to use 'prcomp', please?

How does clusplot exactly make use of cmdscale?
Dear people,
I used clusplot to plot a partition result. The partition result was from
pamk with a distance object as input. Then I applied cmdscale on the same
distance object for coordinates to make another scatterplot.
My problem is this: the coordinates from the cmdscale calculation, though
with the same shape, were different in scale and rotation from the scatter
plot yielded by clusplot.
