Hi,
Here is another problem with data frame subsetting:

aa
1 1
2 2
3 3
A 11
B 12
> `[<-`(df, 5:4, , value=value)
aa
1 1
2 2
3 3
B 12
A 11
This actually produces:
> `[<-`(df, 5:4, , value=value)
aa
1 1
2 2
3 3
A 12
B 11
but should instead produce:
aa
1 1
2 2
3 3
B 12
A 11
sorry for the confusion.
H.
For this last result, the rownames of the 2 last rows should
be swapped.
