pegas: an R package for population genetics with an integrated-modular approach

Area of Science:

• Population genetics
• Evolutionary biology
• Bioinformatics

Background:

• The Population and Evolutionary Genetics Analysis System (pegas) is a novel software package designed for the analysis of population genetic data.
• It is implemented in the R programming language and integrates seamlessly with existing R packages such as ape and adegenet.
• pegas is available through the Comprehensive R Archive Network (CRAN).

Purpose of the Study:

• To introduce pegas, a new R package for population genetic data analysis.
• To provide a comprehensive set of functions for standard population genetic analyses.
• To highlight the utility of R's graphical capabilities for visualizing population genetic data, such as haplotype networks.

Main Methods:

• The pegas package utilizes the R programming language for its implementation.
• It integrates with established R packages like ape and adegenet to leverage existing functionalities.
• The package employs R's graphical capabilities for data visualization, including the creation of haplotype networks.

Main Results:

• pegas offers a suite of functions for common population genetic analyses.
• The package facilitates the visualization of population genetic data, notably through haplotype networks.
• It supports the development of novel analytical methods through its low-level functions.

Conclusions:

• pegas provides a flexible and efficient tool for population genetic data analysis.
• The package promotes an integrated and modular approach to population genetics software development.
• Further development in this integrated-modular software approach is essential for the field.
