Apply a col_spec to a data.frame

Description

cb_apply_col_spec() applies column definitions contained in a col_spec object (typically created using readr::cols()), to the chosen columns in a data.frame.

NOTE: This is currently only implemented for column specifications specifying conversion to a factor variable.

Usage

cb_apply_col_spec(
  d,
  cspec,
  warn_missing_levels = TRUE,
  set_spec_attribute = FALSE,
  set_problems_attribute = TRUE
)

Arguments

d	The data.frame to which the col_spec should be applied.
cspec	The col_spec to apply.
warn_missing_levels	Warn if any values in d don't match the levels of the corresponding factor.
set_spec_attribute	Should the spec attribute of the result be set to the col_spec (for compatibility with readr behavior).
set_problems_attribute	Should the problems attributes of the result be set in case of problems with parsing.

Value

A data.frame based on d, with corresponding columns changed according to the values specified in cspec
