mp_maindataset {manifestoR}

Access the Manifesto Project's Main Dataset

Description

Gets the Manifesto Project's Main Dataset from the project's web API or the local cache, if it was already downloaded before.

Usage

mp_maindataset(
  version = "current",
  south_america = FALSE,
  download_format = NULL,
  apikey = NULL,
  cache = TRUE
)

mp_southamerica_dataset(...)

Arguments

version

Specify the version of the dataset you want to access. Use "current" to obtain the most recent, or use mp_coreversions for a list of available versions.

south_america

flag whether to download corresponding South America dataset instead of Main Dataset. This parameter deprecated as the previously separated South America Dataset has been integrated into the Main Dataset from version 2023a onwards. To allow for backward compatibilty old South American Datasets can still be accessed but querying for the most recent South American Dataset will result in an empty dataset.

download_format

Download format. If not NULL, instead of the dataset being returned as an R data.frame, a file path to a temporary file in the specified binary format is returned. Can be one of c("dta", "xlsx", "sav"). With the "dta" option, labeled columns can be obtained.

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.

...

all arguments of mp_southamerica_data are passed on to mp_maindataset
