Today, the book has been downloaded by >35,000 students from >500 universities. If each book costs $100, we have saved families $3.5M.

Adding links to #roxygen2 docs used to do my head in. But when to use #markdown syntax instead its easy
Add
Roxygen: list(markdown = TRUE)
to your DESCRIPTION file , then swap:
\code{\link[pkg:func]{pkg::func()}}
with
[pkg::func()]
#RStats #package
