The world of data visualization can leave you to choose between expensive software or difficult-to-learn software. lessR simplifies the process of obtaining professional-quality data visualizations at no cost and with minimal effort. Anyone with a computer can download for free both R and its environment for analysis, RStudio. Please find more information at the same website I developed for my students, and you can view many examples.
