This repository is structured as a standard R package following the conventions outlined in the R Packages book. A few additional files are provided that are not part of the built R package and are listed in .Rbuildignore, such as .travis.yml, which is used for continuous testing and integration.
All code for this package is found in R/. All functions should be thoroughly documented with roxygen2 notation; see Documentation. Code should conform to the tidyverse Style guide.
Any new feature or bug-fix should include a unit-test demonstrating the change. Unit tests follow the testthat framework with files in tests/testthat. Please make sure that the testing suite passes before issuing a pull request. This can be done by running check() from the devtools package, which will also check for consistent documentation, etc.
All of the function documentation is generated automatically. Please do not edit any of the documentation files in man/ or the NAMESPACE. Instead, construct the appropriate roxygen2 documentation in the function files in R/ themselves. The documentation is then generated by running the devtools::document() function. Please consult the R Packages book if this workflow is unfamiliar to you. Note that functions should include examples in the documentation. Please use \dontrun for examples that take more than a few seconds.
Similarly, the .md files in the base directory should not be edited directly. Instead, edit the .Rmd source files.
This package already contains a large number of dependencies (imports and suggests). Therefore, new packages should only be added when creating new features that cannot be reasonably achieved within the existing set of dependencies.
These contributing guidelines are based on those of the rOpenSci emld project.
