To help with this communication for USGS R packages, we have created the following categories: In this article, we are going to focus on the most commonly used techniques to install the package in R. Two items from the CRAN policies should be borne in mind when creating examples (and when choosing dontrun/donttest/dontshow toggles ). If you wish there were even more flexibility, be on the lookout for future developments for examples written with roxygen2, for instance check out the WIP roxygen2labs package. https://www.rstudio.com/products/rpackages/ After posts exploring READMEs, URLs in DESCRIPTION, today we shall look at another important aspect of documentation: examples in the manual pages of your functions! R packages are a collection of R functions, complied code and sample data. They increase the power of R by improving existing base R functionalities, or by adding new ones. How to build and install an R package. Ideally your package should have examples for every function. Then by default, it uses the PMM method to impute the missing information. You can use test_examples() in a testthat test file to have examples run by devtools::test() but note that the docs state that “Generally, this is redundant with R CMD check, and is not recommended in routine practice.". If you want to run only one of the examples you’re reading, So long copy paste, Hello Command + Enter!Did you know that you can run code from examples in help files with Command + Enter? For a CRAN submission you might be told to use donttest for examples using a token.

From “Writing R extensions”, “You can use \dontrun{} for text that should only be shown, but not run, and \dontshow{} for extra commands for testing that should not be shown to users” and “Finally, there is \donttest, used (at the beginning of a separate line) to mark code that should be run by example() but not by R CMD check (by default: the option --run-donttest can be used).". A package must be loaded to the current R environment. (This is useful to know as a developer too!). Now comes one of the trickiest aspects of creating examples for the manual pages: sometimes the two goals of examples (examples for the user to try or read; examples for smoke testing) can conflict. Once you have the URL, you can install it using a command similar to the example below: In the introduction to this tutorial, you already learned that the development of dplyr and magrittr occurred around the same time, namely, around 2013-2014. “The code and examples provided in a package should never do anything which might be regarded as malicious or anti-social."
