Read data for selected variables and countries
The object dir specifies the directory path where the PIRLS 2021 data
is located (eg. “/home/data”). Variable selection can be done with aid
of pirls.var.label(dir).
pirls <- pirls.select.merge(folder= dir,
student= c("ITSEX", "ASBG03"),
home= c("ASBHSES", "ASDHSES"),
school= c("ACBG05B"))
Calculate average reading score by country

Read data for selected variables and countries
The object dir specifies the directory path where the PIRLS 2021 data is located (eg. “/home/data”). Variable selection can be done with aid of pirls.var.label(dir).
pirls <- pirls.select.merge(folder= dir,
student= c("ITSEX", "ASBG03"),
home= c("ASBHSES", "ASDHSES"),
school= c("ACBG05B"))
Calculate average reading score by country
