Loading ILSA data into a list — justload • ILSAmerge

Load 'SPSS' data from different International Large-Scale Assessments (ILSA), including: 'TIMSS', 'TIMSS Advanced', 'PIRLS', 'ICCS', 'ICILS', 'CIVED', 'REDS', 'RLII', and 'SITES' (2006) into a list.

Usage

justload(
  inputdir = getwd(),
  population,
  justattributes = FALSE,
  addcountries = FALSE
)

Arguments

inputdir: a string indicating the path were ILSA 'SPSS' files are stored.
population: a character value indicating which files should be merged. For more information on available populations, run ILSAfile.info() first.
justattributes: a logical value indicating if 0 rows should be loaded. This can be used when we just need to check column attributes. Default is FALSE.
addcountries: a logical value indicating if country information should be added to the elements of the list. This means adding the variable CNTRY where needed and adding labels for IDCNTRY where needed. If FALSE (the default), data will be loaded as is. Country information will be retrieved from 'GitHub' if possible. If not, it will use the package internal data.

Value

A list of tibbles.

Examples

# Path were raw 'SPSS' files are
input <- system.file("extdata/reds", package = "ILSAmerge")

# Load only attributes
emptylist <- justload(inputdir = input, population = "BCGV1", justattributes = TRUE)

# Load complete data
fullist <- justload(inputdir = input, population = "BCGV1", justattributes = FALSE)

# Load complete data and add country labels
withcou <- justload(inputdir = input, population = "BCGV1", addcountries = TRUE)
