Использование roxygen2 и doxygen в одной упаковке?

Я лично использую следующий код в пакете dataManagement, который я вызываю во всех моих сценариях. Он содержит документацию и примеры с помощью кислорода. Вы просто просто звоните    документ() и doxygen работает на C-коде, в    SRC/ , Документ помещается в    инст /Doxygen Так что ваш пакет CRAN готов.

Документация R, предназначенная для конечных пользователей R, которые не должны смотреть на код C, я не интегрировал документацию кода C в классическую документацию R, но, вероятно, было бы хорошей практикой скопировать полученную документацию C в виде "виньетка".
