These samples of data might be individual vectors, or they may be columns in a data frame or part of a matrix or list. R is a programming language and software environment for statistical analysis, graphics representation and reporting. If we attempt to add too many details to a plot or too many plots to an array, however, the result can become too complicated to be useful. about how to use high-level programming languages such as R, which allow for easy and intuitive use. R is a programming language and free software developed by Ross Ihaka and Robert Gentleman in 1993. As we have seen, base R graphics provides tremendous flexibility in creating plots with multiple lines, points of different shapes and sizes, and added text, along with arrays of multiple plots.
