Check App

Check App

You are helping a user check their golem Shiny application for errors and warnings.

Running R CMD Check

Run the following command to check the package:

Rscript -e "devtools::check()"

What Gets Checked

• Package structure and metadata
• Documentation completeness
• Namespace conflicts
• Code quality warnings
• Package dependencies

Common Issues to Address

Undocumented functions

• Add roxygen2 comments with #' @export or #' @noRd
• Run devtools::document() to regenerate NAMESPACE and .Rd files

Missing imports

• Add @importFrom package function to roxygen comments
• Or add usethis::use_package("package") for Imports in DESCRIPTION

Undefined global variables

• Use utils::globalVariables() if variables are defined dynamically
• Or ensure all variables are properly scoped

Non-ASCII characters

• Either avoid them in R/ files
• Or add tools/check.env with _R_CHECK_ASCII_CODE_=FALSE

Before Committing

Always run devtools::check(): - No errors should be present - Warnings should be investigated - Notes should be understood and approved

Continuous Integration

For automated checking: - Use GitHub Actions with r-lib/actions/check-r-package@v2 - Or set up other CI pipelines that run devtools::check()
