Quantitative ethnobotany is the study of the use and importance of plants in human cultures, using statistical and analytical methods to quantify and interpret data. This approach has emerged as a key tool for understanding the cultural and ecological significance of plant species, and for evaluating the impact of human activities on plant communities and ecosystems. This manual offers an overview of the basic functions of the ethnobotanyR package for generating figures and performing some very basic quantitative ethnobotany analysis. It offers a general overview and some arguments for and against the use of indices and offers some guidance toward other options for quantitative ethnobotany analysis. It also offers some handy and useful tools for exploratory analysis of ethnobotany data.
