Unnest multi-value variable

Description

Unnests a multi-value variable of type list to long format. Multi-value variables can contain more than one value per observation and thus break with the tidy-data convention. This function allows to conveniently expand data to contain a single var value per observation only, thereby increasing the number of observations (i.e. rows).

Usage

unnest_var(data, var)

Arguments

data	RDB referendum data as returned by rfrnds(). A data frame that at minimum contains the column specified in var.
var	data column to unnest. One of the multi-value variables: topics_tier_1 topics_tier_2 topics_tier_3 inst_object_revision_modes inst_topics_only inst_topics_excluded Tidy selections are supported.

Value

A tibble.
