If "x", the top labels will be displayed to the bottom. . Share. Creating a Scatterplot Matrix. If your text is part of your existing data, simply using the mapping ( aes) argument when calling the function will suffice. I changed some of the columns to factors. By default, ggpairs () provides two different comparisons of each pair of columns and displays either the density or count of the respective variable along the diagonal. The list of current valid ggally_NAME functions is visible in a dedicated vignette. Ensure legends are set to 'TRUE' in the ggpairs function call. ggpairs prints out a progress bar and estimated remaining time while generating plots, which is nice when used interactively since some of the computations can take a few seconds. Sorry for the long code, but most probably only the plot_models function and the line where ggpairs is called need to be modified. ggfacet() Single ggplot2 plot. ”`stat_bin()` using `bins = 30`.
