Scatterplot Matrix in R markdown

Hi @user124578,

Personally, I recommend using ggplot2 for your graphing purposes. Another package named ggforce has provided a extra ggplot2 functionality that does precisely what you are looking for (and a whole lot more). Try this out and let me know what you think:

library(ggplot2)
library(ggforce)

airquality %>% 
  ggplot() +
  geom_point(aes(x = .panel_x, y = .panel_y)) +
  facet_matrix(vars(everything()))

Basically you can replace everything() with the specific variables you want to plot if you do not want all of them plotted at once.
