Use user-defined macros in the manual

It is possible to use user-defines macros in order not to write a new time the package title, the package description, etc. For references, it is also possible to replace the href mark by the doi mark.

\packageTitle
\packageDescription
\packageAuthor
\packageMaintainer
\packageDESCRIPTION
\packageIndices
\doi

See Writing R Extensions (User-defined macros)

This avoids, for example, possible differences between the title of the description file and the title of the package's help page.
