| \title{Attribute Specification} |
| \usage{ |
| structure(.Data, \dots) |
| } |
| \alias{structure} |
| \arguments{ |
| \item{.Data}{an object which will have |
| various attributes attached to it.} |
| \item{\dots}{attributes, specified in \code{tag = value} |
| form, which will be attached to data.} |
| } |
| \description{ |
| \code{structure} returns the given object with further |
| \link{attributes} set. |
| } |
| \details{ |
| Adding a class \code{"factor"} will ensure that numeric codes are |
| given integer storage mode. |
| |
| For historical reasons (these names are used when deparsing), |
| attributes \code{".Dim"}, \code{".Dimnames"}, \code{".Names"}, |
| \code{".Tsp"} and \code{".Label"} are renamed to \code{"dim"}, |
| \code{"dimnames"}, \code{"names"}, \code{"tsp"} and \code{"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 \code{tag = NULL} removes attribute \code{tag} from \code{.Data} if |
| it is present. |
