I have a ranking on that axis, with numbers ranging 1-11, and I want each of them to say, for example, "1°" instead of just "1". Often you may want to add a regression equation to a plot in R as follows: Fortunately this is fairly easy to do using functions from the ggplot2 and ggpubr packages. In case of Base R, the axis limits are changed to make the plot squared; In case of ggplot2, the smaller axis range is visually stretched, but the axis limits are kept the same. npc = "left", label. I've found lots of great documentation for how to insert special characters and Greek letters into axis labels in ggplot in R, but nothing for pasting legend colors In this article, we’ll describe how to easily i) compare means of two or multiple groups; ii) and to automatically add p-values and significance levels to a ggplot (such as box plots, dot plots, bar plots and line plots ).
