skimr solves a very specific set of problems focused on the compact, flexible and useful display of summary data in the console. By itself it is not intended as a replacement for packages that create publication ready tables. The basic concept is that of “skimming” a data frame or tibble to get an overview of the data it contains.
One intended group of users is students in a first semester statistics class. As such, the package is focused on data types that are widely used. One general guideline is that if a data type is not found in the
datasets package it will not be directly supported in
skim() has a generic internal function for handling a variety of data types
get_skimmers(). See the documentation for that function or the vignette “Supporting additional objects” for documentation on how to do this.
skimr is deeply tied to the
dplyr in particular. The comes with a lot of benefits, but some constraints too. Most importantly, data processed by
skim() needs to be an object that inherits from a data frame or in a form that can be coerced to a data frame.
testthat for testing. Please try to provide 100% test coverage for any submitted code and always check that existing tests continue to pass. If you are a beginner and need help with writing a test, mention this in the issue and we will try to help.
Pull requests should be against the develop branch not the master branch. You can set this when creating your pull request. Please make a separately named branch to submit. Keep each branch for a complete specific issue. If you create a pull request by editing in the GitHub web editor and you end up with multiple pull requests, note that in your issue comments.
We follow the tidyverse style guide.
To enforce coding style and support development, we rely on [pre-commit.com], and the R precommit package. This tool runs a series of additional checks for your code before
git commit completes.
To install the package and enable precommits, run the following:
# once on your system remotes::install_github("lorenzwalthert/precommit") precommit::install_precommit() # once in every git repo either # * after cloning a repo that already uses pre-commit or # * if you want introduce pre-commit to this repo precommit::use_precommit()
The checks will run automatically from there.
