R help - Feb 2018 - package MonteCarlo error: object 'packages' not found

R-users,

I can't tell what's causing the following error. The vignette does not 
make a reference to a "packages" option or parameter.

This looks like the sort of thing that you should ask the package
maintainer (?maintainer).
