afrb_build: Build a local copy of the Afrobarometer database

In sboysel/afrobarometer: Load Afrobarometer data

Description

Automates the downloading and merging of the Afrobarometer data. Fetches any missing, publicly available files, creates a master MonetDB database in options(afrobarometer.data), and merges available spatial data with the questionnaires for each round.

Usage

afrb_build(rounds = 1:6, overwrite = FALSE)

Arguments

rounds	A sequence of integers indicating which rounds to build. As of February 2017, there are six rounds. Default is value 1:6.
overwrite	A boolean value indicating whether or not the SQLite database in the local Afrobarometer data directory should be overwritten when afrb_build is run. Default is FALSE.

Details

May only run afrb_round after afrb_dir and before afrb_round.

Value

Builds the database in options("afrobarometer.data"), downloading files as needed into sub-directories and merging the resulting data file.path(options("afrobarometer.data"), "build").

# download first 3 rounds but do not overwrite the existing database.
# This will fail if the database is already populated with merged tables.
afrb_build(rounds = 3:4)
# download all rounds and overwrite the existing database.
afrb_build(rounds = 3:4, overwrite = TRUE)
