bb <- prolfqua::sim_lfq_data_peptide_config()
conf <- bb$config
sample_analysis <- bb$data
pepIntensityNormalized <- transform_work_intensity(sample_analysis, conf, log2)
s1 <- get_robscales(pepIntensityNormalized, conf)

res <- scale_with_subset(pepIntensityNormalized, pepIntensityNormalized, conf)
s2 <- get_robscales(res$data, conf)
abs(mean(s1$mads) - mean(s2$mads)) < 0.1
