Description

This function extracts the unique sequences from several different data objects, including including dada-class and derep-class objects, as well as data.frame objects that have both $sequence and $abundance columns. This function wraps the getUniques function, but return only the names (i.e. the sequences). Can also be provided the file path to a fasta file.

Usage

1
getSequences(object, collapse = FALSE, silence = TRUE)

Arguments

object

(Required). The object from which to extract the sequences.

collapse

(Optional). Default FALSE. Should duplicate sequences detected in object be collapsed together, thereby imposing uniqueness on non-unique input.

silence

(Optional). Default TRUE. Suppress reporting of the detection and merger of duplicated input sequences.

Value

character. A character vector of the sequences.
