legend at fixed distance form the bottom
inset= is measured from the margin so the trick is to inset it relative to the
top even if you want it at the bottom:
legend("top", pch = unique(listSymboles), legend = c("ane", "cheval",
"poney", "mule"),
inset = c(0,1.1), horiz = TRUE, xpd = NA)

Hi the list
I would like to add a legend under a graph but at a fixed distance from the
graphe. Is it possible ?
More precisely, here is my code :
--- 8< ----
symboles <- c(3,4,5,6)
dn <- rbind(matrix(rnorm(20),,5),matrix(rnorm(20,2),,5))
listSymboles <- rep(symboles,each=2)
matplot(t(dn),pch=listSymboles,type="b")
legend("bottom", pch = unique(listSymboles), legend = c("ane", "cheval",
"poney", "mule"), inset = c(0,-0.175), horiz = TRUE, xpd = NA)
--- 8< ----
But when I change the size of the graph, the legend is misplaced.
Instead, I try to put some text in xlab, but I do not know how to get the +,
x , V and other symbol.
Does anyone got a solution ?
Thanks a lot.
Christophe
