    <p>I am trying to plot a bunch of thin-plate spline response surfaces for measurements related to two continuous variables plus one discrete variable. So far, I have been subsetting the data based on the discrete variable to generate pairs of plots, but it seems to me there should be a way to create some slick trellised plots instead. It seems like this could be done by faceting heatmaps in <code>ggplot2</code> with <code>geom_tile</code> and <code>geom_contour</code>, but I am stuck on </p> <p>(1) how to reorganize the data (or interpret the predicted surface data) for plotting with <code>ggplot2</code>? </p> <p>(2) syntax for creating trellised heatmaps with base graphics? or </p> <p>(3) ways to use graphics from <code>rsm</code> to accomplish this (<code>rsm</code> can cope with higher-order surfaces, so I could coerce things to some extent, but plots aren't fully trellised). </p> <p>Here's an example of what I've been working with so far:</p> <pre><code>library(fields) library(ggplot2) sumframe&lt;-structure(list(Morph = c("LW", "LW", "LW", "LW", "LW", "LW", "LW", "LW", "LW", "LW", "LW", "LW", "LW", "SW", "SW", "SW", "SW", "SW", "SW", "SW", "SW", "SW", "SW", "SW", "SW", "SW"), xvalue = c(4, 8, 9, 9.75, 13, 14, 16.25, 17.25, 18, 23, 27, 28, 28.75, 4, 8, 9, 9.75, 13, 14, 16.25, 17.25, 18, 23, 27, 28, 28.75), yvalue = c(17, 34, 12, 21.75, 29, 7, 36.25, 14.25, 24, 19, 36, 14, 23.75, 17, 34, 12, 21.75, 29, 7, 36.25, 14.25, 24, 19, 36, 14, 23.75), zvalue = c(126.852666666667, 182.843333333333, 147.883333333333, 214.686666666667, 234.511333333333, 198.345333333333, 280.9275, 246.425, 245.165, 247.611764705882, 266.068, 276.744, 283.325, 167.889, 229.044, 218.447777777778, 207.393, 278.278, 203.167, 250.495, 329.54, 282.463, 299.825, 286.942, 372.103, 307.068)), .Names = c("Morph", "xvalue", "yvalue", "zvalue"), row.names = c(NA, -26L), class = "data.frame") sumframeLW&lt;-subset(sumframe, Morph=="LW") sumframeSW&lt;-subset(sumframe, Morph="SW") split.screen(c(1,2)) screen(n=1) surf.teLW&lt;-Tps(cbind(sumframeLW$xvalue, sumframeLW$yvalue), sumframeLW$zvalue, lambda=0.01) summary(surf.teLW) surf.te.outLW&lt;-predict.surface(surf.teLW) image(surf.te.outLW, col=tim.colors(128), xlim=c(0,38), ylim=c(0,38), zlim=c(100,400), lwd=5, las=1, font.lab=2, cex.lab=1.3, mgp=c(2.7,0.5,0), font.axis=1, lab=c(5,5,6), xlab=expression("X value"), ylab=expression("Y value"),main="LW plot") contour(surf.te.outLW, lwd=2, labcex=1, add=T) points(sumframeLW$xvalue, sumframeLW$yvalue, pch=21) abline(a=0, b=1, lty=1, lwd=1.5) abline(a=0, b=1.35, lty=2) screen(n=2) surf.teSW&lt;-Tps(cbind(sumframeSW$xvalue, sumframeSW$yvalue), sumframeSW$zvalue, lambda=0.01) summary(surf.teSW) surf.te.outSW&lt;-predict.surface(surf.teSW) image(surf.te.outSW, col=tim.colors(128), xlim=c(0,38), ylim=c(0,38), zlim=c(100,400), lwd=5, las=1, font.lab=2, cex.lab=1.3, mgp=c(2.7,0.5,0), font.axis=1, lab=c(5,5,6), xlab=expression("X value"), ylab=expression("Y value"),main="SW plot") contour(surf.te.outSW, lwd=2, labcex=1, add=T) points(sumframeSW$xvalue, sumframeSW$yvalue, pch=21) abline(a=0, b=1, lty=1, lwd=1.5) abline(a=0, b=1.35, lty=2) close.screen(all.screens=TRUE) </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
