R help - Mar 2008 - [ca package] how to extract x,y from mjca function

Hi,

I would like to extract x,y from mjca function in ca package to be able to
draw other graph types.

For example for simple mca function from MASS I can do the following:

-------------
mydata.mca <- mca(anydata, nf = 2, abbrev = TRUE)

x <- anydata.mca$rs[,1]    #that is what I can 'extract'
y <- anydata.mca$rs[,2]

plot(anydata.mca) #standard plot

library(lattice)
xyplot(x~y)  # I can draw this as well apart from plot or export x,y.
--------------

With ca package and mjca function I have tried so far with every variable
but without succes - anyone can help me? Maybe its simply impossible.

--------------
anydata.mjca <- mjca(anydata, lambda = "JCA")

#x <- anydata.mjca ??? how to get here...
#y <- anydata.mjca ???

plot(mydata.mjca, mass = TRUE, contrib = "absolute", map =
"rowgreen",
arrows = c(FALSE, TRUE)) 
-------------

And I want any configuration of x/y from this plot or any other map/plot
type.

Thanks,
P
