I am using the LIS database in order to calculate the at-risk-of-poverty rate in different countries, broken down by gender. However, the breakdown argument in the syntax does not produce any values, sorted by domain, as intended. I hope it is a mistake of mine and not an error of LISSY. I leave my code below, hopefully someone will be able to help me.

Here is my code:

    library(dplyr) 
    library(laeken) 

    ro20h <- read.LIS('ro20h')
    ro20p <- read.LIS('ro20p')

    ro20h$eqscale <- ro20h$nhhmem^0.5
    ro20h$equii <- ro20h$hitotal/ro20h$eqscale 
    ro20h$indweight <- ro20h$hpopwgt*ro20h$nhhmem 
    Ropdata20 <- merge(ro20h, ro20p, on= "hid")

    arpr( 
      Ropdata20$equii, 
      weights = Ropdata20$indweight, 
      sort = Ropdata20$pid, 
      breakdown = Ropdata20$sex,
      data = NULL,
      p = 0.5, 
      threshold = NULL, 
      na.rm = TRUE)

This is the exact resulting listing:

Value:
[1] 23.29077

Value by domain:

Threshold:
[1] 21117.77
