EdSurvey (version 2.2.3)

readPIAAC: Connect to PIAAC Data

Description

Opens a connection to a PIAAC data file and returns an edsurvey.data.frame with information about the file and data.

Usage

readPIAAC(path, countries, forceReread = FALSE, verbose = TRUE)

Arguments

path

a character value to the full directory to the PIAAC .csv files and Microsoft Excel codebook

countries

a character vector of the country/countries to include using the three-digit ISO country code. A list of country codes can be found in the PIAAC codebook or https://en.wikipedia.org/wiki/ISO_3166-1#Current_codes. If files are downloaded using downloadPIAAC, a country dictionary text file can be found in the filepath. You can use * to indicate all countries available.

forceReread

a logical value to force rereading of all processed data. Defaults to FALSE. Setting forceReread to be TRUE will cause PIAAC data to be reread and increase processing time.

verbose

a logical value that will determine if you want verbose output while the function is running to indicate the progress. Defaults to TRUE.

Value

an edsurvey.data.frame for a single specified country or an edsurvey.data.frame.list if multiple countries specified

Details

Reads in the unzipped .csv files downloaded from the PIAAC Database using the OECD Repository (http://www.oecd.org/skills/piaac/). Users can use downloadPIAAC to download all required files automatically.
