All,
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.
Thanks!
Dave
x = rnorm(10)
y = rnorm(10)
ind = which(x < y)
z = x
z[ind] <- y[ind] ## z now contains the max's
