How can I repeat a data.frame?

Question

It\'s easy to repeat a data.frame once,

mt2 <- rbind(mtcars, mtcars)

But what\'s an R-like way to do this generally? If I want 10 copies

Answer 1

@joran's answer is very elegant and you should use it if duplicating the rownames isn't required. However, this way will also duplicate the rownames:

do.call(rbind, replicate(10, mtcars[1:10, ], simplify=FALSE))
