ggplot (mtcars, aes (sample = mpg, colour = factor (cyl))) + stat_qq + stat_qq_line () Contents ggplot2 is a part of the tidyverse , an ecosystem of packages designed with common APIs and a shared philosophy.
This question showed how to make a qqplot with a qqline in ggplot2 , but the answer only seems to work when plotting the entire dataset in a single graph.. I want a way to quickly compare these plots for subsets of my data. That is, I want to make qqplots with qqlines on a graph with facets . So in the following example, there would be lines for all 9 plots, each with their own intercept.
I was thinking terms like ‘geom_qq’ or ‘stat_qq’ would appear in the second code. – Helena Jul 3 ’20 at 13:25 @Helena yes, the second version is just like a ggplot version of the linked qqPlot , which you can easily test by running my above code then running qqPlot(sample1, sample2) .
stat_qq_point This is a modified version of ggplot2 ::stat_qq with some parameters adjustments and a new option to detrend the points. stat_qq_line Draws a reference line based on the data quantiles, … The Q-Q plot functions are also compatible with many ggplot2 operators, such as Facets (sub-plots).
