Revalue values in a vector

Description

Similar idea to pandas.replace method using a dictionary for the value argument. Note: only works with vectors that are of type numeric (including integer) or character.

Usage

revalue_vector(x, dict, default_value = NULL, suppress_warnings = FALSE)

Arguments

`x`	character. Name of column to be relabelled
`dict`	a named vector. `names(dict)` are the 'keys' i.e. the existing values in `df[[colname]]` to be replaced. These should be unique. An error is raised if non-unique values are found in `names(dict)`
`default_value`	default value to use for values in `df[[colname]]` that are not present in `names(dict)`. By default this is `NULL`, meaning that values not present in `names(dict)` will remain unchanged.
`suppress_warnings`	bool. A warning is raised if the column to be relabelled contains values not present in `dict`. This message is silenced if `suppress_warnings` is `TRUE`. Default value is `FALSE`.
