Hi all!
I am working with R package cluster and I have a little problem:
let's say I have two datasets...first one ("A") is divided into 4 clusters
by means of Pam algorythm.
Let's say I want to project the second database ("B") onto the Comp.1 X
Comp.2 graph, and see where its elements are placed.
The two datasets are made of different dim (54x19 and 28x19). I tried to
extract the $loadings of the A clustering but I can't seem to figure out how
to use them with B :(
Prin <- princomp(A) predict(Prin,B) in the assumption that the variable names in both dataframes are equal.
Using princomp I menaged to extract the $scores and plot the graph. Wouldn't using princomp on the B dataset generate different PC?
Indeed, it would.
Thank you all! Bye!! Claudio -- View this message in context: http://old.nabble.com/R-help-with-princomp-and-pam-clustering-tp26522485p26522485.html Sent from the R help mailing list archive at Nabble.com.
