The package FastaUtils provides tools for the manipulation of DNA/RNA sequence data with R. This package is still work in progress.
FastaUtils depends on Biostrings package which can be installed from Bioconductor (see below).
The current version contains the following functions:
- subset.fasta() Select a subset of sequences from a fasta file
- DNA2RNA() Convert a DNA fasta to an RNA fasta
- RNA2DNA() Convert a RNA fasta to an DNA fasta
- fasta.sample() Select a random sample of sequences
- fasta.cutter() Cuts peaces of a fixed length and a random position for all sequences or for a random sample of sequences
