Examples

bb <- sim_lfq_data_peptide_config(Nprot = 100)
data <- bb$data
conf <- bb$config
res <- apply_to_response_matrix(data, conf, .func = base::scale)

stopifnot("abundance_base..scale" %in% colnames(res))
stopifnot("abundance_base..scale" == conf$table$get_response())
conf <- bb$config$clone(deep=TRUE)
conf$table$workIntensity <- "abundance"
res <- apply_to_response_matrix(data, conf$clone(deep=TRUE), .func = robust_scale)

# Normalize data using the vsn method from bioconductor

if( require("vsn")){
 res <- apply_to_response_matrix(data, conf$clone(deep=TRUE), .func = vsn::justvsn)
}
