Transform lfq data using robscale, vsn or log2 — transform

Assumes that data is not transformed (still needs log2 transformation)

Usage

transform_lfqdata(lfqdata, method = c("robscale", "vsn", "none", "log2"))

Arguments

lfqdata: LFQData
method: normalization method to use

Examples

istar <- prolfqua::prolfqua_data('data_ionstar')$filtered()
#> Column added : nr_peptide_Id_IN_protein_Id
config <- prolfqua:::old2new(istar$config)
tmp <- prolfqua::LFQData$new(istar$data, config)
tmp2 <- transform_lfqdata(tmp)
#> INFO [2026-03-23 19:48:37] Transforming using robscale.
#> Column added : log2_peptide.intensity
#> data is : TRUE
#> Joining with `by = join_by(protein_Id, sampleName, isotope, peptide_Id)`
