[S] Box Cox transformations

Tue, 15 Sep 1998 02:13:53 EDT

My professor says that there is a library called MASS which will identify the
lambda in Box Cox transformations.

He gave us the command

out <- lm(y~x)
temp <- boxcox(out)

When I type library(MASS) at the prompt in S+ Professional, version 4.5, I get
an error message. Is this library resident in S+ or do I have to load it and
if so, from where?
