[R] MASS Library

Looking at the file library/MASS/scripts/ch08.R indicates that R uses a
different syntax for this part of the chapter.

>From this (ch08.R) you need the negexp.SSival function not negexp.ival
to get things working OK,

If things don't work first time using MASS then looking at the scripts
for R for the book is usually a good place to start looking for answers

Hi,

I was just trying out an example on Page 247 of the MASS (Modern Applied
Statistics with S-plus) book and saw the function "negexp.ival".

It says it is supplied in the MASS library, however when I load the
library in R and typed:
  negexp.ival
it says:
  Error: Object "negexp.ival" not found

Does it mean it only appears in the MASS library for S-plus?
