rc_factor: Recodes a character vector into a factor

In graggsd/sgcodebook: Recodes Categorical Values in a Dataset Using a Codebook

Description

Recodes values of x based on pairs of values in from and to, outputting a factor. Optionally allows the ordering of factor levels based on level_idx.

Usage

rc_factor(x, from, to, level_idx = NULL)

Arguments

x	vector that will be recoded and turned into a factor
from	vector containing all unique values in x
to	vector containing values that will replace those in from - should be ordered in a manner so that each value in to occurs in this vector as the corresponding value in from
level_idx	vector specifying the sequence of levels in rc_factor's output - position of each value should be indexed to corresponding value in to and from.

Value

A vector or class factor

Examples

x <- as.character(1:10)
from <- as.character(1:10)
to <- letters[1:10]
level_idx <- rev(1:10)
rc_char(x, from, to, level_idx)
