rgl.attrib.info

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.
