[R] rbind and data.frame

[Göran Broström]

Version 1.3.1  (2001-08-31) (RH 7.2):

> dat <- data.frame(x = 1, y = 2)
> x <- matrix(0, ncol = 2, nrow = 2)
> x
     [,1] [,2]
[1,]    0    0
[2,]    0    0
> dat
  x y
1 1 2
> rbind(dat, x)
  x y
1 1 2
2 0 0

I expected

> rbind(dat, x)
  x y
1 1 2
2 0 0
3 0 0

Is my expectation wrong?
