qtables2

Internal tables function

Internal function to replicate ShortRead::tables functionality while also returning average quals and a map from reads to uniques

qtables2(x, qeff = FALSE, handle.zerolen = TRUE)

`x`	ShortReadQ. The ShortReadQ-class object to table (or dereplicate).
`qeff`	`logical(1)`. Calculate average quality by first transforming to expected error rate.
`handle.zerolen`	`logical(1)`. Default TRUE. If TRUE, gracefully excludes zero-length sequences.

List. Matches format of derep-class object.

Accurate, high-resolution sample inference from amplicon sequencing data
