Description

Coerces all sequences in a DNAbin object to the same length.

Usage

blockAlignment(DNAbin, mode = "shortest", range = NULL, fill = "")

Arguments

DNAbin

An object of class DNAbin

mode

Character vector. Options of "shortest" or "longest"

range

Numeric vector of length 2. Index of the bases where the new alignment should begin and end

fill

Character to fill the extra bases in short sequences. Default of "" (blank). Recommend that only "-" (gap) or "?" be used
