peak_factors

List of factors corresponding to samples in <code>peak_data</code>

datasets

Aligns peak based on peak retention times and matches homologous peaks
across samples. The underlying alignment procedure comprises three sequential steps.
(1) Full alignment of samples by linear transformation of retention times to
maximise similarity among homologous peaks (2) Partial alignment of peaks within
a user-defined retention time window to cluster homologous peaks (3) Merging rows
that are likely representing homologous substances (i.e. no sample shows peaks in
both rows and the rows have similar retention time means). The algorithm is described in detail
in Ottensmann et al., 2018 <doi:10.1371/journal.pone.0198311>.
