Linking to other packages in documentation in roxygen2 in R

Question

I am wondering it there exists a method to link to function from other package when I\'m trying to write a documentation for new package using roxygen2

Answer 1

From the book R packages:

• \code{\link{function}} - function in this package.
• \code{\link[MASS]{abbey}} - function in another package.
• \link[=dest]{name} - link to dest, but show name.
• \code{\link[MASS:abbey]{name}} - link to function in another package, but show name.
• \linkS4class{abc} - link to an S4 class.

Note: In the fourth option there is only one colon, not two as one is used to when referencing functions from other packages in code.
