[R] Details about the boxcox function

[Bert Gunter]

See ?"::"

Many packages hide some of their internal objects, because they are not
meant to be directly called by users. As the Help file referenced above
explains, they can be referenced by the triple colon operatorm in this case:

MASS:::boxcox.lm

See also ?methods and
methods(boxplot)

for further info about how to see and access available methods.
This is all part of R's so-called S3 methods system, for which you should
probably consult an online tutorial if you want to use R to any significant
extent.
