Package Overview

pooledpeaks is designed for analyzing genetic data obtained from Fragment Analysis output files (.fsa) of pooled biological samples. It provides functions for a comprehensive analysis pipeline from processing .fsa files, to cleaning the peak data, and conducting population genetic analyses. Some features are listed below and a usage example of the entire pipeline is included as a vignette.

Features

• Peak Scoring: Process .fsa files and score peaks contained therein.
• Data Manipulation: Clean and prepare peak data for downstream analyses.
• Population Genetics Analysis:
  • Calculate Gene Identity Matrix and Genetic Distance Matrix
  • Calculate diversity indices
  • Calculate differentiation indices
  • Perform cluster analysis
• Visualization: Visualize the peak scoring and genetic analysis results.

The pooledpeaks package was developed by the Blanton Lab as part of Kathleen Kuesters’ dissertation.
