Hi,

I'm trying to repeat the elements of vector a, b number of times. That is, a="abc" should be "aabbcc" if y = 2.

Why doesn't either of the following code examples work?

sapply(a, function (x) rep(x,b))

and from the plyr package,

aaply(a, function (x) rep(x,b))

I know I'm missing something very obvious ...
