A drat repository is a way to make R packages more easily available to end users.

How to use it:

1. Make sure that you have the drat package installed
2. Add this repo to your current session drat::addRepo("inbo")
3. Use install.packages() or update.packages() to install or update the packages

Visit https://inbo.github.io/drat/ for an overview of the available packages.

• Use the Authors@R in the DESCRIPTION. This is required to generate the package website with pkgdown.
• Use a fixed date in the vignette preable. Setting the date to Sys.Date() cause the the vignette to update with easy run of the drat repository, resulting in unnecessary changes in the history of the drat repository.
• In case the vignette uses HTML widgets, make sure that the have stable id's. The reason for this is similar as the fixed dates. It takes only 3 simple steps:
  1. Add htmlwidgets to the DESCRIPTION under Suggests.
  2. Add %\VignetteDepends{htmlwidgets} to the vignette preamble.
  3. Add library(htmlwidgets) and setWidgetIdSeed(my_fancy_number) to the code of the vignette. my_fancy_number can be any integer to your liking.
