Unread Sep 27 2011 101358 AM 92711 to ggplot2 I am trying to add a line to each facet of a plot that shows the average of all points at each x value see the attached plot. These geoms add reference lines sometimes called rules to a plot either horizontal vertical or diagonal specified by slope and intercept. We will first make simple boxplot and then add a layer showing mean values per group and then add a layer connecting the mean values with a line.

I currently have this plot. Examples with code and interactive charts. Skip to first unread message Idris Raja.
Labeling a Horizontal Line in a ggplot2 Plot. Current plot without mean line. The basic idea in making a boxplot with a line connecting mean values is to use ggplot2s layering idea and build one layer on top of the other.
Ggplot2 add straight lines to a plot. Ggplot2 allows to show the average value of each group using the stat_summary function. This tutorial describes how to add one or more straight lines to a graph generated using R software and ggplot2 package.
