Hi Achim,
That was a very quick reply/fix that got posted in between my reading and my
response.
I have downloaded your fix from:
svn checkout svn://r-forge.r-project.org/svnroot/zoo
for the HEAD revision and confirmed that it works as expected - I tested
using the code I posted in the first m
Thank you for your reply, but I am still confused.
Let me clarify... ...my problem isn't with zoo-ness per se.
With zoo objects, there appears to be zoo-matrices and zoo-vectors.
My problem is this - I start with a zoo-matrix:
> x <- m[1,,drop=FALSE]
> x
inp
2003-02-01 5
> is.matr
