[R] using rbind() on multiple objects at once

Is there an efficient way to use rbind() with the five dataframes described in the following example:

a <- c(1:5)
list.foo <- lapply(a, function(x) data.frame(beta=a*rnorm(10), deta=a*rnorm(10)))
big.data.frame <- rbind(list.foo[[1]], list.foo[[2]], list.foo[[3]], list.foo[[4]], list.foo[[5]]) #is there an easier method?

For example, I naively thought you could do something like

rbind(list.foo[[1:5]]) #gives an error message

but that results in an error message.

Thanks,
Andrew
