I love to use citations in my r bookdown projects.
The format is not very flexible, I can use @citeID to get "Author(Year)" or [@citeID] to get "(Author Year)".
Sometimes I only need "(Year)" or "Year" or I may only need "Author Year" with no parentheses at all.
Finally I need to add a page reference to the citation like "Author (Year:Pages)"
Can anybody give me a hint, where the relevant code sits in the source so that I can start adding some cite-formats as described above?
