Similar to Example 1, we simply need to specify the v argument within the abline function: plot ( x, y) # Create plot without lines abline ( v = 1.3) # Add vertical line. On the one hand, you can set the argument x to "top", "topleft", "topright", "bottom", "bottomleft", "bottomright", "left", "right" or "center". The goal of this article is to show you how to add legends to plots using R statistical software. legend with default spacing. a vertical legend). I'd assign an absolute (instead of relative) height to get the same look across differents plots. The heatmaps and simple annotations automatically generate legends which are put one the right side of the heatmap. Note that, the argument legend.position can be also a numeric vector c(x,y). To add vertical lines at median or mean, we need to compute the median/mean values. It follows those steps: always start by calling the ggplot () function. The border type for the overall legend, use bty = "n" for no border. 1.3 Barplot width and space of bars. title: a character string or length-one expression giving a title to be placed at the top of the legend.

We are going to simulate two random normal variables called x and y and use them in almost all the plot examples.. set.seed(1) # Generate sample data x <- rnorm(500) y <- x + rnorm(500) When adding a legend to a plot, there are two main ways to modify the legend position with the R legend function. horiz logical; if TRUE, set the legend horizontally rather than vertically (specifying horiz overrides the ncol specification). Finally, both axes and legends share properties, which is a named list of props() that is applied to specified components of the axis or legend. I was experimenting with <fieldset> and found that I can change the writing-direction and rotation to create a vertical <legend>. This can be one value or multiple values.

In later sections, we first introduce the settings for continuous legends and . Text string, the location of the legend relative to the figure region. Because group, the variable in the legend, is mapped to the color fill, it is necessary to use scale_fill_xxx, where xxx is a method of mapping each factor level of group to different colors. Multiple Density Plots in R with ggplot2. We will continue using the base graphics library functions, so we need not load any additional package. Now we add the legend back in manually. The legend on the topright illustrates the meaning of the two colors of each bar. The margin argument is used to control the vertical spacing between rows in the subplot grid..
