[R]:?alternative to loop

[nicolas baurin]

Hello to all R people,

for the application of a function to each column of a matrix (ex:
function sum()), i'd like to know if there is a simpler (and faster)
alternative to a loop like :

for (i in 1: ncol(m)){sum(m[i])}

Thanks in advance,
Cordialement,
