 # R package pasaR
 We present an R package, named pasaR, usable in the later stages of such an analysis, i.e. after the construction of the gene families for a given set of genomes, based on information of the full complement of gene families. A complete methodology is proposed, suitable for sets of genomes of varying complexity, optimizing and enriching an assortment of existing measures from micropan, the only R package currently available on CRAN for such studies. This is an on-going project so better documentantion, a more extensive vignette and additional functions will be added. However the package is fully functional.
