If you still don’t use ggplot2 or, as I do, the x and y label of the plot each with a sensible default. By moting1a Programming Language 0 Comments. principal component analysis Let’s have a look at the R code and the output: legend("topright", inset = c(- 0.4, 0), # Create legend outside of plot Legends can also be placed inside the plot box using x/y coordinates, where (0,0) is the … The main arguments are: legend: names to display; bty: type of box around the legend. legend.stack. There are many packages in R (RGL, car, lattice, scatterplot3d, …) for creating 3D graphics.This tutorial describes how to generate a scatter pot in the 3D space using R software and the package scatterplot3d.. scaterplot3d is very simple to use and it can be easily extended by adding supplementary points or regression planes into an already generated graphic. April 30, 2014 - how-to, R If you still don’t use ggplot2 or, as I do, have to use the old and finicky plot() function, read on to discover a trick I use to display a legend outside the plotting area.
