rgl.attrib.info: Get information about attributes of objects

In rgl: 3D Visualization Using OpenGL

Get information about attributes of objects

Description

These functions give information about the attributes of RGL objects. rgl.attrib.info is the more “user-friendly” function; rgl.attrib.count is a lower-level function more likely to be used in programming.

Usage

rgl.attrib.info(id = ids3d("all", 0)$id, attribs = NULL, showAll = FALSE)
rgl.attrib.count(id, attrib)

Arguments

id	One or more RGL object ids.
attribs	A character vector of one or more attribute names.
showAll	Should attributes with zero entries be shown?
attrib	A single attribute name.

Details

See the first example below to get the full list of attribute names.

Value

A dataframe containing the following columns:

id	The id of the object.
attrib	The full name of the attribute.
nrow, ncol	The size of matrix that would be returned by rgl.attrib for this attribute.
