Supplemental functions and data for OpenIntro resources, which includes open-source textbooks and resources for introductory statistics at openintro.org. The package contains datasets used in our open-source textbooks along with custom plotting functions for reproducing book figures. The package also contains the datasets used in OpenIntro labs. Note that many functions and examples include color transparency; some plotting elements may not show up properly (or at all) when run in some versions of Windows operating system.
You can install the released version of openintro from CRAN with:
install.packages("openintro")
You can install the development version of openintro from GitHub with:
# install.packages("devtools")
library(devtools)
install_github("OpenIntroStat/openintro")
This package was produced as part of the OpenIntro project. For the accompanying textbook, visit openintro.org. A PDF of the textbook is free and paperbacks can be purchased online (royalty-free).
You can file an issue to get help, report a bug, or make a feature request.
When filing an issue to get help or report a bug, please make a minimal reproducible example using the reprex package. If you haven’t heard of or used reprex before, you’re in for a treat! Seriously, reprex will make all of your R-question-asking endeavors easier (which is a pretty insane ROI for the five to ten minutes it’ll take you to learn what it’s all about). For additional reprex pointers, check out the Get help! section of the tidyverse site.
Before opening a new issue, be sure to search issues and pull
requests to make
sure the bug hasn’t been reported and/or already fixed in the
development version. By default, the search will be pre-populated with
is:issue is:open
. You can edit the
qualifiers
(e.g. is:pr
, is:closed
) as needed. For example, you’d simply remove
is:open
to search all issues in the repo, open or closed.
Process for adding new data to the package
The following steps use the devtools and usethis packages for various steps. We recommend using this process when suggesting new datasets to be added to the package. If the dataset is large (>500MB) or you’d like to add a function, please open an issue first for discussion before making the pull request.
usethis::create_from_github("OpenIntroStat/openintro")
usethis::pr_init("BRANCH-NAME")
,
where BRANCH-NAME
is an informative branch name.data-raw
folder with the name of the
dataset (how you’d like it to show up in the package). Please use
snake_case
for naming, e.g. name_of_dataset
.data-raw
folder, create a new R script called
name_of_dataset-dataprep.R
and write the code needed to read in
the file, make any modifications to the data that are needed (if
any), and end with usethis::use_data()
to save the data in the
package as an .rda file with the ideal compression. See examples
from other folders in data-raw
for sample code. The contents of
this folder do not end up in the package (the entire folder is
ignored in the .Rbuildignore
) so you don’t need to worry about
adding package dependencies etc.R
folder, create an R script called data-name_of_dataset
and add documentation using Roxygen style. See other documentation
files for help with style. In the examples, use tidyverse syntax but
do not use library(tidyverse)
and only use the relevant packages,
e.g. library(dplyr)
, library(ggplot2)
.devtools::load_all()
to make sure the data loads
and run your examples to confirm they all work.devtools::document()
, restart R, and then
devtools::load_all()
. Then, check out ?name_of_dataset
to make
sure the documentation looks as expected.devtools::check()
. The only NOTE you should see as a result of
the check should be about the package size. If any other ERRORs,
NOTEs, or WARNINGs are generated, resolve them or open an issue for
help.pkgdown.yml
file, add the name of the dataset under
reference
, in the correct alphabetical order.NEWS.md
with the new dataset you’ve added with a
link to your GitHub username so we can acknowledge your
contribution, e.g. “added by
@mine-cetinkaya-rundel”.Please note that the openintro project is released with a Contributor Code of Conduct. By contributing to this project, you agree to abide by its terms.
