Hello,
You should post a data example using
dput(head(X, 20)) # or 30
Now, for your question, you can simply set ylim to the reverse order.
Using one of the examples in the stripchart help page,
op <- par(mfrow=c(1, 2))
# First graph, y axis in reversed order
plot(1, typer="n", xlim=c(0, 9), ylim=c(130, 2))
stripchart(decrease ~ treatment,
main = "stripchart(OrchardSprays)",
vertical = TRUE, log = "y", data = OrchardSprays, add=TRUE)
# Second graph, exactly like in ?stripchart
stripchart(decrease ~ treatment,
main = "stripchart(OrchardSprays)",
vertical = TRUE, log = "y", data = OrchardSprays)
par(op)
Hope this helps,
Rui Barradas
