Maybe this helps
par(mar = c(5,4,6,1))
plot(1:10, type = "n", axes = F)
xticks = axis(1, at = c(1,5,9), labels =
c("1-1-2009","1-5-2009","1-9-2009")) #set axis manually
yticks = axis(2, at = 1:10) #set axis manually
abline(v = xticks, col = "gray") #verticall lines
abline(h = yticks, col = "gray", lty = 3) #horizontal lines
legend(8,12, legend = c("test", "test"), col = 1:2, pch = 1:2, xpd = TRUE)
points(1:10)

Hi everyone. I am new to R.
It will be greatly appreciated if someone can help me with the following
questions.
Here's the graph I have just produced.
http://www.nabble.com/file/p24732839/calibration.jpeg
(1) How can I put the legend on top of the grid lines?
(2) How can I match the grid lines with the x-axis ticks?
(3) How can I change the x-axis format from e.g. Mar, Apr...etc to
1-3-2009,1-4-2009...etc?
Many thanks! :-)
Chris
