:?alternative to loop
...,
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,

Graphics: somethink like autoscale
....5) no problem, all
my points are visible on the graph. But if i do points(2,2),
this point is not visible on the plot. I'm looking for a way to adjust
the scale of the x and y axis to see all my points in the window.
Cordialement,
