> rbind(data.frame(x = 1), data.frame(x = 2), data.frame(x = 3))
x
1 1
2 2
3 3
> rbind(rbind(data.frame(x = 1), data.frame(x = 2)), data.frame(x = 3))
x
1 1
2 2
3 3
Above is the result of running the last two lines in "Examples" of 'make.unique'. I don't see the work of 'make.unique' there. It used to work, when there is no automatic row names for data frame.
Perhaps a simpler example is adding columns.
> data.frame(x = 1, x = 2, x = 3)
x x.1 x.2
1 1 2 3
> data.frame(data.frame(x = 1, x = 2), x = 3)
x x.1 x.2
1 1 2 3
