This function returns the type of a variable as character. It
is similar to pillar::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)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.
Logical, if TRUE, returns a shortened, abbreviated value
for the variable type (as returned by pillar::type_sum()).
If FALSE (default), a longer "description" is returned.
The variable type of x, as character.
