Message-ID: <3D77613F.31B79516@bank-banque-canada.ca>

Extending a recent R help discussion:

> xmat2 <- ts(matrix(rnorm(100),ncol=2))
> end(t(xmat2))
 [1] 50  1
# this implies 50 periods of data
> dim(t(xmat2))
 [1]  2 50
# this implies 2 periods of data on 50 series

(In R 1.5.1 on Solaris.) I think this should be considered a bug in t(),
which probably should not preserve ts attributes. I will file it as a
bug unless there are other opinions. I guess there are other
possibilities (such as, the documentation for the structure of a ts
should be changed), but I think t() preserving the mts and ts class and
attributes will probably break lots of other things.
