Grammar of Graphics for base plot

Aesthetic mapping

bb_aes() for aesthetic mapping, that equivalents to ggplot2::aes().

library(bbplot)

p <- bbplot(mtcars, bb_aes(mpg, disp, col=factor(cyl)))
p + bb_point()

Geometric layer

p2 <- p + bb_point() + bb_lm(bb_aes(group=cyl), lwd=2)
p3 <- p2 + bb_lm(col="red", lwd=3, lty='dotted')
par(mfrow=c(1,2))
p2; p3

TODO

  • bb_point
  • bb_lm
  • more layers need to be added

Setting labels

p2 + bb_labs(title = "hello", sub = "just for demo",
              xlab="this is xlab", ylab = "this is ylab") +
  bb_title("hello world") # last one rules

Theme

g <- p2 +
     bb_theme(col.main="red", cex.main=2,
             mar = c(4, 4, 3, 1)) +
     bb_title("applying graphics::par")
par(mfrow=c(1,2))
print(g)
p2 + bb_title("theme has no side effect")

bb_theme has no side effect and will only apply to the bbplot that it added to. This is very important for developing pre-defined themes.

  • develop pre-defined themes
