Update Collate field in DESCRIPTION.

Description

Topologically sort R files and record in Collate field. The topological sort is based on the @include tag, which should specify the filenames (space separated) that should be loaded before the current file - these are typically necessary if you're using S4 or RC classes (because super classes must be defined before subclasses).

Usage

update_collate(base_path)

Arguments

Details

If there are no @include tags, roxygen2 will leave collate as is. This makes it easier to use roxygen2 with an existing collate directive, but if you remove all your @include tags, you'll need to also manually delete the collate field.

This is not a roclet because roclets need the values of objects in a package, and those values can not be generated unless you've sourced the files, and you can't source the files unless you know the correct order.

Examples

#' `example-a.R', `example-b.R' and `example-c.R' reside
#' in the `example' directory, with dependencies
#' a -> {b, c}. This is `example-a.R'.
#' @include example-b.R
#' @include example-c.R
NULL

## Not run: 
  update_collate("my_package")

## End(Not run)
