This function returns the type of a variable as character. It is similar to type_sum, however, the return value is not truncated, and var_type() works on data frames and within pipe-chains.

var_type(x, ..., abbr = FALSE)

Arguments

x

A vector or data frame.

...

Optional, unquoted names of variables that should be selected for further processing. Required, if x is a data frame (and no vector) and only selected variables from x should be processed. You may also use functions like : or tidyselect's select_helpers. See 'Examples' or package-vignette.

abbr

Logical, if TRUE, returns a shortened, abbreviated value for the variable type (as returned by type_sum). If FALSE (default), a longer "description" is returned.

Value

The variable type of x, as character.

data(efc) var_type(1)
#> [1] "numeric"
var_type(1L)
#> [1] "integer"
var_type("a")
#> [1] "character"
var_type(efc$e42dep)
#> [1] "numeric"
var_type(to_factor(efc$e42dep))
#> [1] "categorical"
library(dplyr) var_type(efc, contains("cop"))
