Build a bit flag by checking whether two columns are identical

bf_identical(
  x,
  test,
  against,
  pos = NULL,
  na.val = NULL,
  description = NULL,
  registry = NULL
)

Arguments

x: data.frame(1)
the table that contains test and against.
test: character(1)
the column in x that is checked against.
against: character(1)
the column in x that is checked against test.
pos: integerish(.)
the position(s) in the bitfield that should be set.
na.val: character(1)
optional value that should be used to substitute NA values in the input data.
description: character(.)
optional description that should be used instead of the default function-specific description. This description is used in the registry legend, so it should have as many entries as there will be entries per the respective flag in the legend (two for a binary flag, as many as there are cases for a cases flag and one for count or numeric flags).
registry: registry(1)
a bitfield registry that has been defined with bf_registry; if it's undefined, an empty registry will be defined on-the-fly.

Value

an object of class 'registry' with the additional flag defined here.

Details

This function compares the values of two columns element-wise and returns TRUE when the two columns are identical.
