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.setandas_haven, an object of class"data.set"; foras.item, an object of class"haven_labelled"or"haven_labelled_spss"; an object of class"tbl_df"foras.data.set. user_na-
logical; if
TRUEthen the resulting vectors have an"na_values"and/or"na_range"attribute. row.names-
NULLor an optional character vector of row names. ...-
further arguments, passed through to other the the
as_tibblemethod 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".
