As described @ https://stat.ethz.ch/pipermail/r-help/2012-November/329442.html
I now know how to prepare my netCDF data specifying gas concentrations over a 3D space (dimensions longitude, latitude, and (vertical) level), so as to call lattice::levelplot() like levelplot(conc ~ lon * lat | lev, data=data.frame) which labels each panel in the lattice of plots with the name "lev" plus a graphical indicator of the level value. Alternatively, I can label each panel with an index (i.e., "1", "2", ...) by calling levelplot(conc ~ lon * lat | factor(lev), data=data.frame) However I will need to before-and-after compare this to the results of a reboxing, or 3D regridding, of this data, so I would prefer instead to label each panel in the lattice with the _value_ of the level (an atmospheric pressure), rather than the name or index of the level. How to do that?
