We present an R package, named pasaR, usable in the later stages of an pangenomic 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.

If package devtools is present, simply run:

library(devtools)
install_github("ampatzia/PasaR")

Currently there are available two vignettes for the package, both precompiled in pdf:

• Small case study and example of usage in a pangenome of 81 bacterial strains. .
• Benchmark comparison to package micropan .
