Interface to Packages 'tibble' and 'haven'

Description

A as_tibble method (as_table.data.set) allows to transform "data.set" objects into objects of class "tbl_df" as defined by the package "tibble".

as.item methods for objects of classes "haven_labelled" and "have_labelled_spss" allow to transform a "tibble" imported using read_dta, read_spss, etc. from the package "haven" into an object of class "data.set".

as_haven can be used to transform "data.set" objects into objects of class "tbl_df" with that additional information that objects imported using the "haven" package usually have, i.e. variable labels and value labels (as the "label" and "labels" attributes of the columns).

Usage

as_tibble.data.set(x,...)
## S4 method for signature 'haven_labelled'
as.item(x,...)
## S4 method for signature 'haven_labelled_spss'
as.item(x,...)
as_haven(x,...)
## S4 method for signature 'data.set'
as_haven(x,user_na=FALSE,...)
## S4 method for signature 'item.vector'
as_haven(x,user_na=FALSE,...)
## S4 method for signature 'tbl_df'
as.data.set(x,row.names=NULL,...)

Arguments

`x`	for `as_tibble.data.set` and `as_haven`, an object of class `"data.set"`; for `as.item`, an object of class `"haven_labelled"` or `"haven_labelled_spss"`; an object of class `"tbl_df"` for `as.data.set`.
`user_na`	logical; if `TRUE` then the resulting vectors have an `"na_values"` and/or `"na_range"` attribute.
`row.names`	`NULL` or an optional character vector of row names.
`...`	further arguments, passed through to other the the `as_tibble` method for lists, or ignored.

Value

as_tibble.data.set and the "data.set"-method of as_haven return a "tibble". The "item.vector"-method (which is for internal use only) returns a vector with S3 class either "haven_labelled" or "haven_labelled_spss".
