It is one of the most popular languages used by statisticians, data analysts, researchers and marketers to retrieve, clean, analyze, visualize and present data. Welcome to the community! Faceting is similar to grouping, but it creates separate plots for each level of a variable by basically creating subsets of the data. In order to produce graphical output, the user calls a series of graphics functions, each of which produces either a complete plot, or adds some output to an existing plot. The code for base graphics is in the graphics package, which is loaded by default when you start R. Grid graphics is an alternative graphics system that was later added to R. The big difference between grid and the original base graphics system is that grid allows for the creation of multiple regions, called viewports, on a single graphics page. These are some pretty sweet looking graphs. This means that, you don’t need to read the different chapters in sequence. With more knowledge and time, you can customize your graphics even more to create better visualizations. To keep it short, graphics in R can be done in three ways, via the: {graphics} package (the base graphics in R, loaded by default) {lattice} package which adds more functionalities to the base package If you want to create a vector of type integer, you need to provide a value with the postfix L to it. Note: As you can see, it is possible to group by numeric variables as well as categorical variables because ggplot2 will automatically scale them. You will find this step more important for variable names with unknown meanings to most viewers, such as 'x.'.
