[R] Trying to eliminate a for loop

[Steven Wolf]

I keep trying to eliminate for loops when I arrive at them, but this one is
stumping me.  What is the nifty way to do this?

My object data.cca is the output of the cancor function (for some two
datasets X and Y) (data.cca is a numeric vector)

data.cca <- cancor(X,Y)

Xcen=0*X
for(i in 1:dim(X)[1]){
	Xcen[i,]=data.cca$xcenter
	}
Xc = X - Xcen
