What I need is a barchart or vertical dotchart, with error bars, across three treatments, with a form that should look something like: barchart(median~fac1|by1, groups=group1).

Cylinders and No. Geom_errorbar It contains two types of temperatures measured, one of these are mean values. Re. Here we start by specifying the dodge (the spacing between bars) as well as the upper and lower limits of the x and y axes.

Deepayan Sarkar has provided a very useful solution for simple circumstances (https://stat.ethz.ch/pipermail/r-help/2005-October/081571.html), yet I am having trouble getting it to work when the "groups" setting is enabled in xyplot (i.e.

Turns out, R makes this pretty easy with just a couple of tweaks to our code! We use srt = 45 for a # 45 degree string rotation text(x = barCenters, y = par("usr")[3] - 1, srt = 45, adj = 1, labels = myData$names, xpd = Error Bars In R Baking at a lower temperature than the recipe calls for Efficiently find whether a string contains a group of characters (like substring but ignoring order)?
