Usage

pisa.mean.pv(pvlabel, by, data, export = FALSE, name = "output", 
     folder = getwd())

Arguments

pvlabel	The names of columns corresponding to the achievement plausible scores, for example, paste0("PV",1:10,"MATH").
by	The label for the grouping variable, usually the countries (i.e., by="IDCNTRYL"), but could be any other categorical variable.
