[R] predicting fuzzy cluster membership

I'm trying to obtain a fuzzy clustering with fanny from the cluster package,
using a given set of data. That worked just fine.
I have another separate sample of data from the same problem. For each case in
this new sample I would like to know their membership coefficients with
respect to the clustering obtained with the first dataset. In effect I want
to have a kind of prediction of the probability that each case in the new set
belongs to each of the clusters formed with the first set of data. I do not
want to add the second ssample to the first and build a new clustering
because that would change the initial clustering.
I've looked in the help pages of the cluster package for some similar example
with no success. I've also searched the R mailing list but didn't find any
Is there any easy way of obtaining this matrix of cluster membership values
for the new set of data?
Thank you in advance,
