Usage

pirls.mean.pv(pvlabel = "ASRREA", by,  
data, export = FALSE, name = "output", folder = getwd())
pirls2016.mean.pv(pvlabel = "ASRREA", by,  
data, export = FALSE, name = "output", folder = getwd())

Arguments

pvlabel	The label corresponding to the achievement variable, for example, "ASRREA", for overall reading performance.
by	The label for the grouping variable, usually the countries (i.e., by="IDCNTRYL"), but could be any other categorical variable.
data	An R object, normally a data frame, containing the data from PIRLS.
