Components of a pillar

Description

new_pillar_component() constructs an object of class "pillar_component". It is used by custom ctl_new_pillar() methods to create pillars with nonstandard components.

pillar_component() is a convenience helper that wraps the input in a list and extracts width and minimum width.

Usage

new_pillar_component(x, ..., width, min_width = NULL)

pillar_component(x)

Arguments

x	A bare list of length one (for new_pillar_component()), or an object with "width" and "min_width" attributes (for pillar_component()).
...	These dots are for future extensions and must be empty.
width, min_width	Width and minimum width for the new component. If min_width is NULL, it is assumed to match width.

Details

Objects of class "pillar" are internally a named lists of their components. The default components for pillars created by pillar() are: title (may be missing), type, and data. Each component is a "pillar_component" object.

This class captures contents that can be fitted in a simple column. Compound columns are represented by multiple pillar objects, each with their own components.

Examples

new_pillar_component(list(letters[1:3]), width = 1)
pillar_component(new_pillar_title("letters"))
pillar_component(new_pillar_type(letters))
pillar_component(pillar_shaft(letters[1:3]))
