presR

presR is a software package designed for the analysis of population genetic data, specifically focusing on the estimation of demographic parameters. It provides a framework for conducting population genetic inference using various statistical models. The primary goal of presR is to facilitate the reconstruction of demographic histories of populations from genetic markers.

The package implements coalescent-based methods, allowing users to model population size changes, migration rates, and divergence times. It is particularly useful for studies investigating phenomena such as population bottlenecks, expansions, and splits. presR supports the analysis of different types of genetic data, including single nucleotide polymorphisms (SNPs) and microsatellites, and can handle both diploid and haploid organisms.

Key features of presR include the ability to simulate genetic data under specified demographic scenarios, which aids in model evaluation and parameter exploration. It also offers tools for visualizing results, such as demographic trajectories and parameter posterior distributions. The package is typically used in conjunction with other bioinformatics tools for data preparation and visualization. presR aims to provide a user-friendly interface for researchers to explore complex population genetic questions.
