Well, that explains why I don't have a copy on my machine. It's dated 6 May

No documentation for ‘pp.test’ in specified packages and libraries:
you could try ‘??pp.test’
You are asked to include the package name for non-base R functions.

Well I do have the MASS package from which that function was loaded.
I get no error with the example in the help page:
boxcox(Days+1 ~ Eth*Sex*Age*Lrn, data = quine,
lambda = seq(-0.05, 0.45, len = 20), plotit=TRUE)
... and you are not providing a reproducible example that provokes the error,
nor are you providing the version numbers of R or MASS.

I get no error after:
library(demography)
# And then running that code.
I have an almost up-to-date version of R running on a mac (and at the moment I
have way too many packages loaded:
