The sdtmchecks package contains functions to identify common data issues in SDTM data. These checks are intended to be generalizable, actionable, and meaningful for analysis.

Installation

Main version (main branch)

You can install {sdtmchecks} from GitHub repo pharmaverse/sdtmchecks@main:

# install.packages("devtools")
devtools::install_github("pharmaverse/sdtmchecks", ref = "main")

Note: The release from main branch is the recommended version for end users.

Development version (devel branch)

The development version (based on the default devel branch) can be installed via:

install.packages("sdtmchecks", repos = "https://pharmaverse.r-universe.dev")  

Or, via GitHub repo pharmaverse/sdtmchecks@HEAD:

# install.packages("devtools")
devtools::install_github("pharmaverse/sdtmchecks")

# Note that `ref = "devel"` is not needed since devel is the default branch

Contributing

This package has been developed internally at Roche since 2014. There may be areas where the checks expect Roche-specific SDTM implementation choices. Proposed additions or modifications should attempt to maintain generalizability for slightly different data standards across companies. For examples on how to do so and to learn more about contributing in general, please refer to the Writing a New Check page.

If you have an idea for a new check but no time for development, please open an issue.
