dataTable-class: Reference Class for Data Frame-like Objects

Description Fields Methods

Description

Objects from this class behave rather like data.frame objects, but are formal reference classes so that computations with them use reference semantics

Fields

data

An environment whose objects correspond to the "columns" of a data frame or matrix.

row.names

The names for the "rows", treated as those in a data frame.

Methods

initialize(..., data = data.frame())

This method takes data= as a named argument, but coerces it to be an environment, instead of requiring that it already be one.
