Using source subdirectories within R packages with roxygen2
documentation, package, r, roxygen
Solution
Writing R Extensions has this to say (in Section 1.1.5) about subdirectories under the R directory:
The `R` and `man` subdirectories may contain OS-specific subdirectories named `unix` or `windows`.
Implied in this is that they can't have other subdirectories other than those two. This is confirmed in an r-devel thread and again later in another r-devel thread.
Problem
I would like to use a directory structure within the `R` folder for the source code of a package. For example, within my `R` folder I have an `algos` folder with functions I want to export and document. However `roxygen2` by default does not seem to go through the subfolders of the `R` folder. I tried to use the `@include` keyword as follows for a file at `R/algos/algo1.r' ``` #' @include algos/algo1.r ``` but without success. Is there a simple way to use subfolder for the `R` source code?
