dqcheckrGUI

A point-and-click Shiny interface for dqcheckr — automated data quality checks for recurring dataset deliveries.

Use this if you want to configure and run quality checks without writing any R code. If you prefer scripting, use dqcheckr directly.

Status: maintenance mode

dqcheckrGUI is feature-complete. It receives bug fixes and compatibility updates only — configuration features are developed in dqcheckr itself. Existing deployments continue to work unchanged.

Since dqcheckr 0.3.0 the whole workflow this interface provides is available as plain function calls, with no Shiny app to run:

# inspect a real delivery, write a fully-commented YAML config
generate_dataset_config("input_data/sales/2026-07.csv", dataset_name = "sales")

validate_config("sales")   # check the config before you rely on it
run_dq_check("sales")      # run the checks, render the report
list_runs("sales")         # what the history screen used to show

The generated YAML documents every available option inline, so it is meant to be read and hand-edited. See vignette("workflow", package = "dqcheckr") for the full walkthrough, including drift comparison and fixed-width files.

What it does

• Walks you through setting up quality checks for a new dataset (wizard)
• Runs checks against incoming file deliveries and opens the HTML report
• Browses historical check results and drift comparisons

Installation

# Install dqcheckr first (required)
install.packages("dqcheckr")

# Install dqcheckrGUI from GitHub
# devtools::install_github("mickmioduszewski/dqcheckrGUI")
install.packages("dqcheckrGUI", repos = c('https://mickmioduszewski.r-universe.dev', 'https://cloud.r-project.org'))

Launch

dqcheckrGUI::run_app()

Or, if you have downloaded the source, double-click launch.command (Mac), launch.sh (Linux), or launch.bat (Windows).

Example configuration files

Example YAML configuration files using the Star Wars dataset are included with the package. Copy them to a local folder to use as a starting point:

file.copy(
  system.file("extdata/example_config", package = "dqcheckrGUI"),
  "my_config",
  recursive = TRUE
)
