The caret package (short for Classification And REgression Training) contains functions to streamline the model training process for complex regression and classification problems. The package utilizes a number of R packages but tries not to load them all at package start-up (by removing formal package dependencies, the package startup time can be greatly decreased). The package “suggests” field includes 30 packages.
Caret is most likely to appear on Data Scientist job descriptions where we found it mentioned 1.3 percent of the time.
