Scatterplot matrices in R.
I just discovered a handy function in R to produce a scatterplot matrix of selected variables in a dataset. The base graphics function is pairs(). Producing these plots can be helpful in exploring your data, especially using the second method below.
Try it out on the built in iris dataset. (data set gives the measurements in cm of the variables sepal length and width and petal length and width, respectively, for 50 flowers from each of 3 species of iris. The species are Iris setosa , versicolor , and virginica ).
Looking at the pairs help page I found that there’s another built-in function, panel.smooth(), that can be used to plot a loess curve for each plot in a scatterplot matrix. Pass this function to the lower.panel argument of the pairs function. The panel.cor() function below can compute the absolute correlation between pairs of variables, and display these in the upper panels, with the font size proportional to the absolute value of the correlation.
Finally, you can produce a similar plot using ggplot2, with the diagonal showing the kernel density.
Update: A tip of the hat to Hadley Wickham (@hadleywickham) for pointing out two packages useful for scatterplot matrices. The gpairs package has some useful functionality for showing the relationship between both continuous and categorical variables in a dataset, and the GGally package extends ggplot2 for plot matrices.
