Hi all,
I am plotting data using the simple plot function:
plot(data$x, data$y)
which results in a standard plot with the axis origin in the lower left corner.

Since my data are screen coordinates I need mirrored axis so that the

Anybody know how? I did not find any parameter when consulting the
help file. I assume its a more general parameter but where is that
documented?
Hi Ralf,
I don't know of any options or call to "par" that will change which axes
are displayed. You can do what you want like this:
plot(...,xaxt="n")
axis(3,...)
unless you want to reverse the direction of the ordinate (y-axis). In
that case, have a look at the revaxis function in the plotrix package.
