Subject: t() of a time series (PR#1998)
Message-ID: <200209101354.PAA05410@pubhealth.ku.dk>

(In R 1.5.1 )

t() preserves time series attributes but not ts structure:

> 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

The time attributes and ts class should be removed by t().
