hgd()

Open the displayed URL in a browser, or call hgd_browse() to open one automatically.

Any plotting code will work:

x <- seq(0, 3 * pi, by = 0.1)
plot(x, sin(x), type = "l")

library(ggplot2)
ggplot(mpg, aes(displ, hwy, colour = class)) +
  geom_point()

Close the device when done:

dev.off()
