Hello,
Just flip 'xlim' or 'ylim'. Or both.
Using the iris example in help("grid"), make the following changes:
op <- par(mfcol = c(2,2)) # Two columns, first is the original, second
flipped.
with(iris,
[... etc ...]
# row 1, col 2: flip x axis
plot(Sepal.Length, Sepal.Width, col = as.integer(Species),
xlim = c(8, 4), ylim = c(2, 4.5), panel.first = grid(),
main = "with(iris, plot(...., panel.first = grid(), ..) )")
# row 2, col 2: flip y axis
plot(Sepal.Length, Sepal.Width, col = as.integer(Species),
xlim = c(4, 8), ylim = c(4.5, 2),
panel.first = grid(3, lty=1,lwd=2),
main = "... panel.first = grid(3, lty=1,lwd=2), ..")
[... etc ...]
)
par(op)
Hope this helps,
Rui Barradas
