Hi,

Here is another problem with data frame subsetting:

   > df <- data.frame(aa=1:3)
   > value <- data.frame(aa=11:12, row.names=c("A", "B"))

   > `[<-`(df, 4:5, , value=value)
     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

For this last result, the rownames of the 2 last rows should
be swapped.

   3  3

   B 11

but should instead produce:

     aa
   1  1
   2  2
   3  3
   B 12
   A 11

sorry for the confusion.
