Ggplot add line. Libraryggplot2 ggplotdf aesxweight geom_histogram ggplotdf aesxweight geom_histogrambinwidth1 p. To add both lines we add both geom_vline and geom_hline function to ggplot function and set the values of xintercept and yintercept. To add a regression line on a scatter plot the function geom_smooth is used in combination with the argument method lm.

You can quickly add vertical lines to ggplot2 plots using the geom_vline function which uses the following syntax. Library ggplot2 ggplot rpt aes xJDay geom_line aes yw colorFirst line geom_line aes ywolf colorSecond line labs colorLegend text. H_line.
Use it with care. Dual Y axis with R and ggplot2. As you can see it consists of the same data points as Figure 1 and in addition it shows the linear regression slope corresponding to our data values.
Collapses the two variables psavert and uempmed into key-value pairs. This tutorial describes how to add one or more straight lines to a graph generated using R software and ggplot2 package. Prepare the data using the tidyverse packages.
Figure 2 shows our updated plot. Note that this kind of chart has major drawbacks. Lets consider a dataset.
