[R] When I cbind the POSIXct gets lost

[Gabor Grothendieck]

Use data.frame:

> tt <- ISOdate(2000, 1:3, 1)
> cbind(tt, tt)
            tt        tt
[1,] 946728000 946728000
[2,] 949406400 949406400
[3,] 951912000 951912000
> data.frame(tt, tt)
                   tt                tt.1
1 2000-01-01 12:00:00 2000-01-01 12:00:00
2 2000-02-01 12:00:00 2000-02-01 12:00:00
3 2000-03-01 12:00:00 2000-03-01 12:00:00
