evanverse: Utility Functions for Data Analysis and Visualization

evanverse is a comprehensive R utility package by Evan Zhou that provides a unified toolkit for data analysis, visualization, and bioinformatics workflows. It combines practical functions for package management, data processing, color palettes, plotting, and workflow automation.

Features

• 📦 Package Management: Multi-source installation (CRAN, GitHub, Bioconductor), version checking, and updates
• 🎨 Color & Visualization: Bioinformatics color palettes, plotting functions (Venn, forest, bar, pie, density)
• 🔧 Data Processing: Flexible file I/O, gene ID conversion, void value handling, column mapping
• 🧮 Operators & Logic: Custom infix operators (%p%, %is%, %nin%, %map%, %match%), logical utilities
• 🌐 Download & Network: URL downloading with retry, GEO data fetching, batch operations
• ⚙️ Workflow Tools: Timing, reminders, safe execution, interactive viewing
