**Greg's Research » R**, and kindly contributed to R-bloggers)Here are a few more plotting options for boxplots:

Let’s start plotting the full set

`plot(b$mod, b$x)`

Plot labels for a subset in full set plot (label all points x < -1)

`text(subset(b$mod, b$x < -1), subset(b$x, b$x < -1), subset(b$site, b$x < -1), cex=0.6, pos=4, col="red")`

Plot subset with x > -1

`plot(subset(b$mod, b$x > -1), subset(b$x, b$x > -1))`

Plot horizontal gridlines

`grid(nx = NA, ny = NULL)`
