This repository provides the underlying code and data for the Climate and Health Outcomes Research Data Systems (CHORDS) Training and Use Cases Toolkit. The CHORDS Toolkit seeks to aid researchers in accessing, processing, and integrating geospatial data-based exposures into their health research by providing guides, tutorials, and example code. The CHORDS Toolkit is available at https://niehs.github.io/PCOR_bookdown_tools/.
The CHORDS Toolkit chapters are written using R Markdown files and the book is created using the bookdown
R
package.
Please note that the CHORDS Toolkit is a work in progress. The following chapters are currently in development:
Title | Unit | Description |
---|---|---|
Calculating Geographic Covariates | Geospatial Data Foundations | A tutorial introducing concepts and methods used to calculate common geographic covariates with public environmental data in R. |
Comparison of Spatial Regression Methods | Advanced Methods | A comparison of spatial regression methods used to develop exposure models for geospatial exposure assessment. |
Linkage to Exposures | Health Data Integration | A tutorial with code in R for linking geocoded addresses to environmental exposure data. |
This is a BETA Release. Please let us know of any improvements we can make.
You can contact us by email or by opening an issue. Please open an issue to suggest edits or to ask questions relating to the code in this repository.
The following code installs the R
packages used in the example code:
install.packages(
c(
"bookdown", "plotly", "shiny", "tidycensus", "tidyverse", "viridis",
"ggmap", "ggplot2", "maps", "dplyr", "knitr", "latticeExtra", "pals",
"classInt", "sf", "udunits2", "tmap", "lubridate", "gifski",
"magick", "cowplot", "BiocManager"
),
dependencies = TRUE
)
BiocManager::install("Biobase")
The following code creates a local HTML version of the book:
bookdown::render_book("index.Rmd", "bookdown::gitbook")
This guide describes the workflow, file organization, and status checks used for contributing to the CHORDS Toolkit.
The following figure illustrates the workflow rules and branch protections.
Development branches are used to create new chapters and to revise existing chapters. Development branches should be named with the contributor's initials, a short description, and the branch creation date (MMDD), as in the following example: mm-unittests-0405
.
A pull request must be opened to merge a development branch into the staging
branch. The pull request must pass all status checks.
The branch staging
is used to review changes before publication.
Only minor edits, such as fixing a broken link or typo, should be made directly to staging
. Contributors should use a development branch for any substantial edits, such as adding a new chapter.
A pull request must be opened to merge the staging
branch into the main
branch. Pull requests into main
are only accepted from staging
. This branch protection is enforced by the Protect Branch main
status check. Pull requests from staging
into main
require at least one review.
When a pull request passes all status checks, is reviewed, and is merged into the main
branch, a new version of staging
will automatically be created (see .github/workflows/update-staging-public.yml). Do not manually create a new staging
branch.
The branch main
is used to display the public CHORDS Toolkit web page. A push (closed and merged pull request) to the main
branch will automatically build and deploy the public CHORDS Toolkit web page.
The main
branch can not be edited directly and can only be edited using the workflow outlined above.
Please use the chapter template file in the templates
folder to create a new chapter RMD
file in the chapters
folder of your development branch. You can then add any images, datasets, and bibliography entries in the images
, dataset
, and bibliography
folders, respectively.
Check Super Linter
Checks that RMD
and style files have valid source code and consistent formatting (.github/workflows/check-super-linter.yml) using super-linter/super-linter.
Check Render Bookdown
Checks for errors in rendering the book (.github/workflows/check-render-bookdown.yml).
Protect Branch main
Checks that a pull request into main
is from staging
(.github/workflows/protect-main.yml).
