Get the levels for a price index

Methods to get and set the levels for a price index.

Usage

# S3 method for class 'piar_index'
levels(x)

# S3 method for class 'piar_index'
levels(x) <- value

set_levels(x, value)

Arguments

x

[piar_index] A price index, as made by, e.g., elementary_index().

value

[character] A character vector, or something that can be coerced into one, giving the replacement levels for x.

Value

levels() returns a character vector with the levels for a price index.

The replacement method returns a copy of x with the levels in value. (set_levels() is an alias that's easier to use with pipes.)
