The R programming language provides several functions to create visualizations, such as plots. Some com-

monly used plot functions in R include:

plot(): a general function for creating plots. It can be used to

create line plots, scatter plots, and other types of plots.

barplot(): creates a bar plot, which is a type of plot that displays

data as rectangular bars.

scatterplot(): creates a scatter plot, which is a type of plot that

displays the relationship between two continuous variables.

pie(): creates a pie chart, which is a type of plot that displays data

as a set of pie slices.

heatmap(): creates a heatmap, which is a type of plot that displays

data as a matrix of colored cells.

These functions and many others are part of the base R package and can be easily used to create various

types of plots. In addition, there are many other packages available in R that provide additional plotting

capabilities, such as the ggplot2 and lattice packages.
