`variable`	The label corresponding to the observed variable, for example, "AGE_R" for age of respondent.

`data`	An R object, normally a data frame, containing the data from PIAAC.

`name`	The name of the exported file.
`folder`	The folder where the exported file is located.
`config`	Object with configuration of a given study. Should contain the slot 'prefixes' with prefixes of filenames with the student, home, school, and teacher data.
