Unlike scatter plots the x- and y-coordinates are not visualized through points but are instead connected through lines. Custom the general theme with the theme_ipsum function of the hrbrthemes package. To add a regression line on a scatter plot the function geom_smooth is used in combination with the argument method lm. This is a linear model fit so I use method lm. Libraryggplot2 sp. How to Plot a Linear Regression Line in ggplot2 With Examples You can use the R visualization library ggplot2 to plot a fitted linear regression model using the following basic syntax.
