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.
The syntax to draw a line plot using plot() function is
plot(x, y, type="l")
In the following program, we will take two vectors in
y, and plot a line graph, using plot() function.
x <- c(1, 2, 3, 4) y <- c(4, 7, 8, 10) plot(x, y, type = "l")
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.
x <- seq(0, 20, 0.5) y <- sin(x) plot(x, y, type = "l")
sIn this R Tutorial, we learned how to plot a line graph in R, using plot() function, with the help of example programs.
