S7 wrappers for key S3 classes

Source: R/S3.R
base_s3_classes.Rd

S7 bundles S3 definitions for key S3 classes provided by the base packages:

  • class_data.frame for data frames.

  • class_Date for dates.

  • class_factor for factors.

  • class_POSIXct, class_POSIXlt and class_POSIXt for date-times.

  • class_formula for formulas.

The concrete wrappers declare their supported attributes, so new_object() strips foreign attributes when constructing S7 subclasses.

Usage

class_Date

class_POSIXct
