Linking R package vignettes

Question

Is there any way I can include links between package vignettes in R? I know I can link between section, for example

# Section 1 {#section1} My first section  # Section 2 A link to [Section 1](#section1) 

But is there any way I can get a clickable link that will launch the HTML doucment of another vignette? Or is it just easier to give the code to launch it?

```r vignette("my vignette", package = "myPackage") ``` 

Note I have generated all of my vignettes using Rmarkdown and knitr.

Answer 1

Yes, this is simple. Vignettes are all stored in the same directory, so you simply refer to the appropriate file name. The drat package vignettes have several examples of this. Here is a link from one vignette to the other:

This vignette deals with the first case: How to use [drat](http://dirk.eddelbuettel.com/code/drat.html) as a package author.  A [companion vignette for package users](DratForPackageUsers.html) is available as well. 

This will work on CRAN and on a user's machine.

You should also be able to link from vignettes to documentation, and vice versa, on a user's machine, knowing that vignettes are stored in library/PKGNAME/doc/ and documentation is stored in: library/PKGNAME/html/.
