A word cloud (or tag cloud) is a visual representation of text data. Tags are usually single words, and the importance of each tag is shown with font size or color. This mode of representation is useful for quickly perceiving the most prominent terms in a list and determine their relative prominences. In R, two libraries will allow you to create wordclouds: Wordcloud and Wordcloud2. In this post I will introduce the main features of the awesome Wordcloud2 library developed by Chiffon Lang.
Welcome to the R graph gallery! One year ago, I realised that I was tired of learning how to code R charts again and again so I decided to create a reproducible code for each of them. I ultimately designed a new R graph gallery: a website that currently provides more than 200 R graphics and explains how to generate them.
