Try this:

Transform the data inside the geom_vline() function to obtain a tidy dataset with the mean and the 0.95 quartile.
Map the geom_vline() aesthetics to the 2x2 dataset from step 1.
Edit the linetype and colour scales to add a line with the metric string (¿"Medida", "Medición"?), and another one with its name (media, normal). Unfortunately, IMHO, this looks ugly.

Add white spaces between two words in a label using ggtext

Asked 2021-Feb-15 at 17:46

I using the ggtext package for formatting the axis labels of a plot made by ggplot2, specifically the function element_textbox_simple(), and I have some issues with the html format to introduce white spaces or a blank space between words.

In the above plot, each axis label have two levels:

Name of the variables (e.g. niceness)
A second line with a tag which describe each extreme value of the respective axis (e.g. jerk - nice)

For achieve this "multi-level label" I used ggtext to format the label with the following html expression:

Perhaps you can just annotate the text you want as shown below. Please note the clip="OFF" in coord_cartesian

Also, you can repeat the same for y-axis.

ANSWER

Answered 2020-Jun-26 at 14:13

The issue is that by changing the labels in scale_linetype but not for the other scales (color and shape) ggplot2 will no longer merge them into one legend. Hence you have the change the labels for the other scales as well. However, using Tex() I did not manage to make this work. But following this post using bquote worked fine. Finally, to get rid of the legend title simply use labs() to set the title for all three scales to NULL

EDIT Thanks to @mischva for checking and pointing out that using labels <- unname(TeX(c(" $\\lambda_1$", "$\\lambda_2$"))) will also work fine. Interestingly it does not work if one puts it directly into the three scales functions. That's what I tried.
