### Load Packages
require(SGP)
require(data.table)
### Utility function
strtail <- function (s, n = 1) {
if (n < 0)
substring(s, 1 - n)
else substring(s, nchar(s) - n + 1)
}
strhead <- function (s, n) {
if (n < 0)
substr(s, 1, nchar(s) + n)
else substr(s, 1, n)
}
### Load Data
WIDA_IN_Data_LONG_2022 <- fread("Data/Base_Files/WIDA_ACCESS_IN_2021_2022.txt")
### Clean Up Data

### Check for duplicates
setkey(WIDA_IN_Data_LONG_2022, VALID_CASE, CONTENT_AREA, YEAR, GRADE, ID, SCALE_SCORE)
setkey(WIDA_IN_Data_LONG_2022, VALID_CASE, CONTENT_AREA, YEAR, GRADE, ID)

setkey(WIDA_IN_Data_LONG_2022, VALID_CASE, CONTENT_AREA, YEAR, GRADE, ID)
### Reorder
setcolorder(WIDA_IN_Data_LONG_2022, c(9, 10, 7, 4, 3, 5, 8, 6, 1, 2))
### INVALIDATE cases
WIDA_IN_Data_LONG_2022[is.na(GRADE), VALID_CASE:="INVALID_CASE"]
### Save data
save(WIDA_IN_Data_LONG_2022, file="Data/WIDA_IN_Data_LONG_2022.Rdata")
