[R] strange row numbering after rbind-ing a list

[Carl Witthoft]

"Not that it really matters, but"
Can someone explain how the row numbers get assigned in the following 
sequence? It looks like something funky happens when rbind() coerces 
'bar' into a dataframe.
In either sequence of rbind below, once you get past the first two rows, 
the row numbers count normally.


Rgames> (foo<-data.frame(x=5,y=4,r=3))
   x y r
1 5 4 3
Rgames> (bar<-list(x=4,y=5,r=6))
$x
[1] 4

$y
[1] 5

$r
[1] 6

Rgames> (foobar<- rbind(foo,bar))
   x y r
1 5 4 3
2 4 5 6

Rgames> (foobar<- rbind(foobar,bar))
   x y r
1 5 4 3
2 4 5 6
3 4 5 6


Rgames> (barfoo<-rbind(bar,foo))
    x y r
2  4 5 6
21 5 4 3

Rgames> (barfoo<-rbind(barfoo,foo))
    x y r
2  4 5 6
21 5 4 3
3  5 4 3
