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.
:bulb: DIZtools contains all “lightweighted” functions
of DIZutils
making it a lot quicker to install, while DIZutils
has a lot of dependencies and system requirements.
You can install DIZtools directly from CRAN:
install.packages("DIZtools")The development version can be installed using
install.packages("remotes")
