We can also combine all the steps for preparing ILSA data
(downloading, merging, combining respondents, and renaming) with the
function ILSAready():
dir.create(file.path(tempdir(),"rlii1991"),showWarnings = FALSE)
output <- file.path(tempdir(),"rlii1991")
ILSAready(study = "RLII", year = 1991,outputdir = output, agreeLicense = TRUE)
