Recently I needed a schematic graph of traditional vs on-demand computing (don’t ask) – and in this hand waving setting I just wanted the axes to show arrows and no labels. So, here it is:
x <- c(1:5)
y <- rnorm(5)
plot(x, y, axes = FALSE)
u <- par("usr")
arrows(u[1], u[3], u[2], u[3], code = 2, xpd = TRUE)
arrows(u[1], u[3], u[1], u[4], code = 2, xpd = TRUE)And here is the output
(I pinched this off a mailing list post, so this is my due reference)
Next thing I am toying with are these xkcd like graphs in R here.
