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:
-------------
anydata.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(anydata.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
