Find tags on rgl objects.

Objects with material properties may have an arbitrary string set as a tag. This function retrieves the id values associated with a given tag, or the tags set on given ids.

tagged3d(tags = NULL, ids = NULL, full = FALSE, subscene = 0)

Arguments

tags

A vector of tags to use for selection.

ids

A vector of ids to report the tags on.

full

logical; whether to return a dataframe containing id, type, tag, or a vector of ids or tags.

subscene

Where to look: by default, the whole scene is searched. NA restricts the search to the current subscene, or a subscene id can be given.

Details

Exactly one of tags and ids must be specified.

Value

A dataframe is constructed with columns

id

item id

type

item type

tag

item tag

matching the specified tags or ids value. If full = TRUE, the full dataframe is returned, otherwise just the requested ids or tags.

If ids is specified, the return value will be in the same order as ids).
