DIZtools

CRAN Status Badge Cran Checks Dependencies R CMD Check via {tic} linting test-coverage codecov

The R package DIZtools provides utility functions used for the R package development infrastructure inside the data integration centers (‘DIZ’) to standardize and facilitate repetitive tasks such as setting up a database connection or issuing notification messages and to avoid redundancy.

💡 DIZtools contains all “lightweighted” functions of DIZutils making it a lot quicker to install, while DIZutils has a lot of dependencies and system requirements.

Installation

You can install DIZtools directly from CRAN:

install.packages("DIZtools")

The development version can be installed using

install.packages("remotes")
remotes::install_github("miracum/misc-diztools", ref = "dev")
