Scaling with Ranked Subsampling (SRS) normalization of a phyloseq object
Source:R/normalize_pq.R
srs_pq.Rd
Wrapper around SRS::SRS() (Heidrich et al. 2021,
doi:10.7717/peerj.9593
) which scales all samples to a common count
Cmin while preserving the rank order of OTU abundances.
Arguments
- physeq
(required) a
phyloseq-classobject obtained using thephyloseqpackage.- Cmin
(integer) the common scaling depth. Defaults to
min(sample_sums(physeq)).- ...
Additional arguments passed on to
SRS::SRS().
Value
A new phyloseq-class object with the SRS
normalised otu_table.
Examples
data_f_srs <- srs_pq(data_fungi_mini)
sample_sums(data_f_srs)
