Of course I longer recall the details but I think what I tried was
essentially to do table(..., exclude = exclude) in a way that would use
the table() heuristics for getting dimnames as if table() had been
called directly (rather than via ftable()).
Now the problem in what we currently have is that in the above:
R> x <- 1:2
R> y <- 3:4
R> ftable(z = x+1, y)
y 3 4
x + 1
2 1 0
3 0 1
and the first one should definitely be 'z' ... at least, according to my
original intentions :-)
And of course, pls note that we have
R> table(z=x+1, y+1)
z 4 5
2 1 0
3 0 1
in both r-release and r-devel so perhaps this is the problem we need to
fix first ...
Best
