[R-sig-Geo] Constraining z axis for 2-study period plot of smoothed surface

Many geographical studies sample across a landscape, create a smoothed surface from the sampling stations, then repeat the sampling and smoothing across study periods. I wish to produce paired plots of two-study periods with sampling station values plotted over their smoothed surfaces. In the plo
