About This Book
Purpose and Scope
This book is designed to serve as both a learning resource and a reference guide for data analysis in the natural sciences, with applications spanning forestry, agriculture, ecology, environmental science, marine biology, and related disciplines. Whether you’re a student, researcher, technician, professional, or hobbyist in these fields, this book will help you develop the skills needed to analyze and visualize data effectively using R.
The focus is on practical applications rather than theoretical statistics, with an emphasis on techniques commonly used across natural science disciplines. By working through this book, you will:
- Master the fundamentals of data analysis in R
- Learn to import, clean, and organize various types of scientific data
- Develop skills in exploratory data analysis and visualization
- Apply appropriate statistical tests for different research questions
- Create publication-quality visualizations
- Implement reproducible research workflows
- Interpret and communicate results effectively
Features of This Book
This book includes:
- Step-by-step instructions for R with complete code examples
- Practical examples using real datasets from various natural science disciplines
- Exercises to reinforce learning and build skills
- Tips and best practices from experienced researchers
- Reproducible code that can be adapted for your own research
- Professional formatting of data and model outputs
Professional Data and Model Output Formatting
Throughout this book, we use several R packages to create professionally formatted tables and model outputs suitable for publications:
- knitr: The core package for dynamic report generation, allowing seamless integration of R code with text
- kableExtra: For creating elegant, publication-quality tables with customizable styling
- gt: For producing beautiful, highly customizable tables with advanced formatting options
- broom: For converting statistical model outputs into tidy data frames that are easier to work with
- sjPlot: For creating publication-ready tables and plots from statistical models
- gtsummary: For creating publication-ready analytical and summary tables
- flextable: For creating tables that work well across different output formats (HTML, PDF, Word)
These tools help transform raw data and complex statistical outputs into clear, professional presentations. Each chapter demonstrates how to use these packages to format your results effectively, following best practices in scientific publishing. You’ll learn to:
- Format regression tables with proper statistical notation
- Create elegant summary tables with appropriate precision and units
- Generate publication-ready ANOVA tables
- Design custom table themes that match your publication requirements
- Export formatted tables to various formats (HTML, PDF, Word)
The code examples throughout the book show not just how to perform analyses, but how to present the results professionally—a critical skill for scientific communication.
