elem: Display Information about Elements in a Given Object

In gdata: Various R Programming Tools for Data Manipulation

Description

This function is depreciated. Please use ll instead.

Display name, class, size, and dimensions of each element in a given object.

Usage

elem(object=1, unit=c("KB","MB","bytes"), digits=0,
                 dimensions=FALSE)

Arguments

object	object containing named elements, perhaps a model or data frame.
unit	required unit for displaying element size: "KB", "MB", "bytes", or first letter.
digits	number of decimals to display when rounding element size.
dimensions	whether element dimensions should be returned.

Details

A verbose alternative to names().

Value

A data frame with named rows and the following columns:

Class	element class.
KB	element size (see notes).
Dim	element dimensions (optional).

Note

The name of the element size column is the same as the unit used.

Elements of class classRepresentation, ClassUnionRepresentation, and grob do not have a defined size, so 0 bytes are assumed for those.
