structure {base}R Documentation

Attribute Specification

Description

structure returns the given object with further attributes set.

Usage

structure(.Data, ...)

Arguments

.Data an object which will have various attributes attached to it.
... attributes, specified in tag=value form, which will be attached to data.

Details

Adding a tsp attribute will ensure that the object returned inherits from class "ts", and adding a levels attribute ensures that the returned object is a factor. These conversions are deprecated: they give a warning and will be removed in R 2.5.0.

For historical reasons (these names are used when deparsing), attributes ".Dim", ".Dimnames", ".Names", ".Tsp" and ".Label" are renammed to "dim", "dimnames", "names", "tsp" and "levels".

It is possible to give the same tag more than once, in which case the last value assigned wins. As with other ways of assigning attributes, using tag=NULL removes attribute tag from .Data if it is present.
