[R] DataFrame help

[voidobscura]

Alright, so I am trying to write my own function to calculate column sums in
a matrix.  I want the result as a single list with the values.

So far I have:

csum<-function(m)
{
	a = data.frame(m)
	s = lapply(a,sum)
	return(s)
}

What is the easiest way to have it return in a format such as [1] 6 15 24 ?

Thanks.
