keymapping: Map a variable

In optimist/inhouse: In-house all-purpose functions used at CI Estrategias

Description

Sometimes we need to map one vector into another. For inhouse data it can be useful when defining categories for carteras modelo, id's or emisoras. This function maps origin -> target for every value of x.

Usage

keymapping(x, origin, target, replace_missing = FALSE)

Arguments

x	The vector that will be transformed; x must have values in origin.
origin	A vector
target	A vector of the same length as origin
replace_missing	Indicates whether the values of x that are not found origin should be changed. If replace_missing is given a value other than FALSE then this value will be used as replacement for the values of x not found in origin.

Value

A transformed vector

Examples

keymapping(1:6, c(2,3), c(-1, -2))
keymapping(1:6, c(2,3), c(-1, -2), replace_missing = NA)
