Consequently: Your procedure must rather be
1) Y0 <- Y - mY
2) Z0 <- Q' %*% Y0
3) Z <- Z0 + mY
and to make this work with data matrices Y, Z,
the mean vector mY must either be a matrix with constant
columns or the result of as.vector()ing such a matrix.

Well, but cut(

Cool.
Actually, now I think the merge() is the much easier part than
the cutree() / as.hclust.dendrogram() one.
But also that should not be very hard.
As I'm officially in vacation at the moment, I may have some fun
helping with these...

Thank you, Joshua.
Note that "R 2.12.1 patched" and "R 2.13.0 unstable"
have this fixed (since yesterday) and hence will no longer "overshoot".

Everything else has been by contributed by R users who were not
happy with S4 ... at the time at least ...

Even more reliable (probably) would be to use the (recommended)

Indeed this whole topic really belongs to R-devel not R-help.
