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).
as_tibble.data.set(x,...)
# S4 method for haven_labelled
as.item(x,...)
# S4 method for haven_labelled_spss
as.item(x,...)
as_haven(x,...)
# S4 method for data.set
as_haven(x,user_na=FALSE,...)
# S4 method for item.vector
as_haven(x,user_na=FALSE,...)
# S4 method for tbl_df
as.data.set(x,row.names=NULL,...)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".
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.
logical; if TRUE then the resulting vectors
have an "na_values" and/or "na_range" attribute.
NULL or an optional character vector of row names.
further arguments, passed through to other the the
as_tibble method for lists, or ignored.
