How to draw a Line Plot in R?

R – Line Plot

To draw a line plot in R, call plot() function and along with the data to plot, pass the value “l” for “type” parameter.

In this tutorial, we will learn how to use plot() function to draw line plot, with example programs.

Syntax

The syntax to draw a line plot using plot() function is

plot(x, y, type="l")

Examples

In the following program, we will take two vectors in x and y, and plot a line graph, using plot() function.

example.R

x <- c(1, 2, 3, 4)
y <- c(4, 7, 8, 10)
plot(x, y, type = "l")

Output

Now, let us take a vector x: sequence of values from 0 to 20 in steps of 0.5, and vector y: sin(x). We plot a line graph using these two vectors: x, y.

example.R

x <- seq(0, 20, 0.5)
y <- sin(x)
plot(x, y, type = "l")

Output

Conclusion

sIn this R Tutorial, we learned how to plot a line graph in R, using plot() function, with the help of example programs.
