R help - Dec 2003 - mca

Dear All,
I want to 'impose' supplementary points to an mca plot -- using V&R
MASS
library -- and I wonder if anyone had any luck.  The book (4th edition) says it
can be done using predict.mca but there are no examples provided in the help
pages.
Would appreciate any help/pointers.
Thanks Marwan

btw, to Professor Ripley -- the abbrev=TRUE option for labels does not seem to
work.

What about 
 points(predict(mcaObject, newdata = newData))
?

Why do you think so? At least the example in ?mca works.
