Hard to help, since we do not know what "ca" actually is (and we could 
only guess).
If you mean the one in a package also called "ca": Please report the bug 
to the maintainer of the package rather than to R-help and tell him to 
use x[i,j,drop=FALSE] for matrix indexing if a matrix is assumed as the 
output (just a guess, but if this is not the problem, it may cause other 
hicc ups).

Best,
Uwe Ligges
