seqbind: Combine Sequences by Rows Without Recycling

Description

Take vectors and/or matrices arguments and combine them row-wise without recycling them (as is the case with rbind).

Usage

seqbind(..., blank = "-")

Arguments

...

vectors, matrices, and/or alignment ‘fasta’ objects to combine.

blank

a character to add to short arguments, to achieve the same length as the longer argument.

Value

Returns a list of class "fasta" with the following components:

ali

an alignment character matrix with a row per sequence and a column per equivalent aminoacid/nucleotide.

id

sequence names as identifers.

call

the matched call.
