load(system.file("extdata", "results.Rda", package = "sporeg"))

results <- lapply(results, data.table::rbindlist, idcol = 'resolution')
results <- data.table::rbindlist(results, idcol = 'iteration')
results <- results %>%
left_join(tibble(resolution = 1:4,
res_name = c("100km", "50km", "25km", "10km")),
by = "resolution")

df_var <- zero_var(results)
