I think I know what you mean. I suppose that you have already set up a suite of
wrapper functions around base graphics for your convenience? That's the
direction I would go, but it sounds you may have done so already. Like the
following?
myDepthPlot <- function(depth, value, value2, ylim = rev(range(depth)), ...)
plot(value, depth, ylim = ylim, ...)
if (!missing(value2)) myDepthPoints(depth, value2, ...)
}
myDepthPoints <- function(depth, value, ...) { points(value, depth, ...) }
Also, you may want to look into Dan Kelley's most excellent OCE package:
http://dankelley.github.com/oce/
Neither of the above reconfigures the coordinate system, but they allow the
user to access functionality as if it were.
Cheers,
Ben
