Is there one liner way to obtain the max per observation for two vectors?
I looked at apply and lapply but it seems that groundwork would have to
be done before applying either of those. The code below does it but seems
like overkill.


x = rnorm(10)
y = rnorm(10)

ind = which(x < y)
z = x
z[ind] <- y[ind] ## z now contains the max's
