Hello,
I want to do a simple correspondence analysis in R, using the ca package.
First, I create and define a 2-by-2-table (table=table(var1,var2)), which looks
like this:
Low(var1) high(var1)
Low(var2) 35 28
High(var2) 26 32
Var1 and Var2 are categorical factors.
When I want to run the ca on this table (typing ca(table)),
I get the following error message:
Fehler in t(obj$rowcoord[, 1:nd]) : Indizierung außerhalb der Grenzen
(subscript out of bounds)
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
I don’t know why the ca command doesn’t work, can you help me?
Thanks!!
