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.
