mp_metadata: Get meta data for election programmes

Description

Get meta data for election programmes

Usage

mp_metadata(ids, apikey = NULL, cache = TRUE)

Arguments

ids

list of partys (as ids) and dates of elections, paired. Dates must be given either in the date or the edate variable, formatted in the way they are in the main data set in this package (date: as.numeric, YYYYMM, edate: as.Date()), see mp_maindataset Alternatively, ids can be a logical expression specifying a subset of the Manifesto Project's main dataset. It will be evaluated within the data.frame returned by mp_maindataset such that all its variables and functions thereof can be used in the expression.

apikey

API key to use. Defaults to NULL, resulting in using the API key set via mp_setapikey.

cache

Boolean flag indicating whether to use locally cached data if available.

Value

an object of class ManifestoMetadata, subclassing data.frame as well as tbl_df and containing the requested metadata in rows per election programme
