seq_consensus: Find a consensus sequence for a set of sequences.

Description

Find a consensus sequence for a set of sequences.

Usage

seq_consensus(x, method = "chr_majority", weights = NULL, gaps = TRUE)

Value

A consensus sequence

Arguments

x

a DNA, RNA or AA vector.

method

the consensus method (see Details).

weights

an optional numeric vector of same length as x giving a weight for each input sequence.

gaps

logical. Should the gaps ("-") taken into account.

Details

"chr_majority", "chr_ambiguity", "seq_centrality", "seq_majority"

For chr_ambiguity gap character always override other characters. Use gaps = FALSE to ignore gaps.
