I am making lattice plots of oceanographic data. The usual layout does not conform to plotting conventions that marine scientists use when depth is the independent variable. Under those conventions, plots are made with the origin at the upper left, depth on the vertical axis (increasing as it goes down), and the dependent variable on the horizontal axis (increasing to the right).
That convention has implications not just in how axes are labeled and set up, but also when using smoothing routines such as panel.lowess(), because the smoothed values are on the horizontal axis, not the vertical axis.
Before I start looking at and modifying the R code that makes up the relevant routines, I wonder if any reader has already developed R routines for this purpose?
