All the graphs (bar plot, pie chart, histogram, etc.) we plot in R programming are displayed on the screen by default. We can save these plots as a file on disk with the help of built-in functions. It is important to know that plots can be saved as bitmap image (raster) which are fixed size or as vector image which are easily resizable.
