blastr - Using NCBI BLAST with R
The Basic Local Alignment Search Tool (BLAST) is a suite of programs that are used to find regions of local similarity between biological sequences and to calculate the statistical significance of the matches.
The blastr package provides R wrappers around the most common BLAST
functions, allows both local and remote queries using standard DNAStringSet
or AAStringSet representations of sequences, and provides parsers for
BLAST XML and tabular output.
