Test, Identify, Select and Mutate Categorical or Continuous Values

Methods and utilities for testing, identifying, selecting and mutating objects as categorical or continous types. These functions work on both atomic vectors as well as recursive objects: data.frames, data.tables, tibbles, lists, etc..

Test For and Identify Categorical or Continuous Values

CRAN_Status_Badge License

This collection of methods and utilities allows for a working with vectors at a higher level abstraction, i.e. by whether they are categorical (nominal) or continous. The functions allow for testing, identifying, selecting, mutating,etc. and work with both atomic vectors and recursive objects (table and list-like) objects in a tidyverse compliant way.
