WLSplot is a new R package that simplifies the analysis and graphical display of survival data, particularly for Caenorhabditis elegans lifespan studies. It automates statistical information and generates editable plots for easy interpretation and further research.

Area of Science:

  • * Biology
  • * Bioinformatics
  • * Genetics

Background:

  • * Analyzing lifespan data, especially for model organisms like *Caenorhabditis elegans*, requires specialized tools for accurate statistical interpretation and graphical representation.
  • * Existing methods may lack integrated features for automated statistical annotation and customizable plot generation.
  • * Efficiently visualizing survival curves with key statistical insights is crucial for understanding genetic or environmental effects on lifespan.

Purpose of the Study:

  • * To introduce WLSplot, an R package designed for streamlined analysis and graphical visualization of lifespan survival data.
  • * To provide researchers with a user-friendly function that automates the generation of survival curves with integrated statistical information.
  • * To facilitate the analysis of various experimental setups, including RNAi, Genotype, and Drug treatments, with a focus on *Caenorhabditis elegans*.

Main Methods:

  • * Development of an R package, WLSplot, incorporating a single function for comprehensive lifespan data analysis and plotting.
  • * Integration of automated statistical calculations, including significance testing (p-values and asterisks) against control groups.
  • * Generation of output in editable Scalable Vector Graphics (SVG) format for further customization and data summary for advanced manipulation.

Main Results:

  • * WLSplot successfully analyzes and plots multiple lifespan experiments in bulk, accurately italicizing gene names.
  • * The package automatically adds significance indicators (asterisks and p-values) to survival curve legends when differences from control are observed.
  • * Outputs are provided as editable SVG files, along with data summaries, enabling flexible downstream analysis and presentation.

Conclusions:

  • * WLSplot offers a powerful and efficient solution for analyzing and visualizing *Caenorhabditis elegans* lifespan data.
  • * The package simplifies complex survival data analysis, making it accessible for researchers with varying statistical expertise.
  • * WLSplot enhances data interpretation by providing publication-ready, editable graphical outputs with integrated statistical significance.
