# This is an example of how to read multiple files at once in LISSY

# To read multiple years of one country:

library(tidyverse)


years <- c("08", "10", "14", "16")


it_df <- purrr::map_dfr(.x = years,
                        .f = ~read.LIS(glue::glue("it{.x}p"), vars = c("year", "educlev", "educ_c", "enroll", "sex", "age" )))
table(it_df$educlev, it_df$educ_c)


# OR to read multiple datasets:


library(tidyverse)


ccyy <- c("it08", "at10", "be14")


df <- purrr::map_dfr(.x = ccyy,
                        .f = ~read.LIS(glue::glue("{.x}p"), vars = c("year", "educlev", "educ_c", "enroll", "sex", "age" )))
nrow(df)
