CRAN Task Views

CRAN task views aim to provide some guidance which packages on the Comprehensive R Archive Network (CRAN) are relevant for tasks related to a certain topic. They give a brief overview of the included packages which can also be automatically installed using the ctv package. The views are intended to have a sharp focus so that it is sufficiently clear which packages should be included (or excluded) - and they are not meant to endorse the “best” packages for a given task.

To automatically install the views, the ctv package needs to be installed, e.g., via

The task views as a whole are overseen and coordinated by the CRAN Task View Editors and each individual task view is maintained by a group of volunteers. See the repository of the CRAN Task View Initiative for details on how to contribute to an existing task view or propose a new one.
