Read (write) FASTA sequences into (from) named character vectors

Description

read_fasta reads sequences in FASTA format in named character vectors. write_fasta writes sequences stored as named character vectors into FASTA file.

Usage

read_fasta(file)

write_fasta(x, file)

Arguments

file	FASTA format file
x	Named characters

Details

Names of sequences to be written do not have to begin with the greater-than sign, as they are appended by the function when writing. Similarly, the read_fasta removes the leading greater-than sign of sequence names.

Value

For read_fasta, a named character vector of FASTA sequences.

For write_fasta, the side effect is used and no value is returned.
