Geom_abline intercept slope linetype color size. Plot faithful lines faithfuleruptions fitted fit colblue Another useful function is abline. Regression model is fitted using the function lm.
In this tutorial we will learn how to add regression lines per group to scatterplot in R using ggplot2. To add a linear regression line to a scatter plot add stat_smooth and tell it to use method lm. Below we use the EuStockMarkets data set available in R data sets to.
With the ggplot2 package we can add a linear regression line with the geom_smooth function. As you have seen in Figure 1 our data is correlated. The income values are divided by 10000 to make the income data match the scale.
Pressure. This instructs ggplot to fit the data with the lm linear model function. X.
