[R] R help with princomp and pam clustering

[Tyler82]

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 :(
Using princomp I menaged to extract the $scores and plot the graph. Wouldn't
using princomp on the B dataset generate different PC? 
Thank you all!
Bye!!

Claudio
