R: Attribute Specification

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 class `"factor"` will ensure that numeric codes are given integer storage mode.

For historical reasons (these names are used when deparsing), attributes `".Dim"`, `".Dimnames"`, `".Names"`, `".Tsp"` and `".Label"` are renamed 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.
