Can someone explain why starts1 and starts2 are diffferent in the example below?
After running this program
a <- c(1:3)
b <- c(2:3)
tsa <- ts(a)
tsb <- ts(b, start = 2)
arr <- cbind(tsa, tsb)
starts1 <- cbind(start(tsa), start(tsb))
starts2 <- apply(arr, 2, start)
I get:
> starts1
[,1] [,2]
[1,] 1 2
[2,] 1 1
> starts2
tsa tsb
[1,] 1 1
[2,] 1 1
Thanks for the help.
