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.
