Source: R/amplicon.R
seqtab_stats.Rd

Given a seqtab matrix, this function will calculate the counts and abundances of ASVs and by their sequence lengths. FREQ is the number of ASVs, and ABUNDANCE is the total number of reads for each sequence length.

Usage

seqtab_stats(seqtab)

Arguments

seqtab

A DADA2 sequence table

Details
