                          ABSTRACT

          My personal recipes when using R ⟨https://
     r‐project.org/⟩.


1.  Intro

     I use R mainly for plotting and some data post‐process‐
ing.   This  document collects some tricks I encountered and
use.

     For plotting I use ggplot2 ⟨https://github.com/
tidyverse/ggplot2/⟩, which ist assumed to exist in these ex‐
amples.  A variable p is typically a ggplot2 plot object.

2.  Hiding Legend, but Preserving its Space

     To hide a legend, but still take up its space (e.g.  to
build  plots  over  multiple instances) add the following to
the legend.  Adjust the aesthetic used.


     p <‐ p +
         guides(fill=guide_legend(override.aes=list(fill=NA))) +
         theme(legend.text=element_text(color="#00000000"),
               legend.title=element_text(color="#00000000"))
