How to plot graph in R language?

To plot a graph in R, you can use the plot() function. This function takes several arguments, including the data to be plotted, the type of graph to create, and options for customizing the appearance of the graph.

Here is an example of how to use the plot() function to create a simple line graph in R:

1
2
3
4
5
6

# First, create some data to plot
x <- c(1, 2, 3, 4, 5)
y <- c(2, 4, 6, 8, 10)

# Then, use the plot() function to create a line graph
plot(x, y, type = "l")

This will create a line graph with the x-axis representing the values in the x vector and the y-axis representing the values in the y vector.

You can also customize the appearance of the graph by specifying additional arguments in the plot() function. For example, you can add a title to the graph using the main argument, add labels to the x- and y-axes using the xlab and ylab arguments, and customize the colors and line styles using the col and lty arguments.

For more information on the plot() function and other ways to create and customize graphs in R, you may want to consult the documentation for the graphics package or seek out other resources on plotting in R.

There are many different types of graphs that can be created in R language. Here are some basic examples using the built-in dataset "mtcars":

1. Scatterplot:

1

plot(mtcars$mpg, mtcars$wt)

1. Barplot:

1

barplot(table(mtcars$cyl))

1. Boxplot:

1

boxplot(mtcars$mpg, mtcars$cyl)

1. Line chart:

1

plot(mtcars$mpg, type="l")

1. Histogram:

1

hist(mtcars$mpg, breaks=10)

1. Density plot:

1

plot(density(mtcars$mpg))

Depending on the graph you want to create, you may need to adjust various parameters such as the x and y axes, titles, labels, color, and so on. There are many resources available online to learn more about R graphing, including the R documentation and various books and tutorials.
