Unnest multi-value variable

Source: R/rdb.gen.R
unnest_var.Rd

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.
