R Cook Book tropf ABSTRACT My personal recipes when using R . 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 , 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")) 21 June 2023
