I'd like to annotate an xyplot with an R^2 value, but can not find the
syntax to define the superscript format for the text.
I'd appreciate suggestions,
xyplot(SharkSloughEggs.df$Sharkeggs.rel +
SharkSloughEggs.df$SharkHatched.rel + SharkSloughEggs.df$SharkFlooded.rel +
HSI.shark$MEAN ~ Year,
pch=c(1,9,5,4), lty=c(1,6,3,4), lwd = c(2), col = c("black",
"blue", "green", "red"),
scales=list(tick.number=length(Year)), data=SharkSloughEggs.df,
ylab="Relative Egg Success",
main="Shark Slough Alligators",
par.settings = graph.sets, type = "b")
trellis.focus()
panel.text(x=1999, y = 0.95, labels="Hatched Eggs\nR^2
= -0.18", cex = 0.75)
panel.text(x=1998, y = 0.35, labels="Number of
Eggs\nR^2 = 0.43",cex = 0.75)
panel.text(x=1995, y = 0.25, labels="Flooded Eggs\nR^2
= -0.50", cex = 0.75)
panel.text(x=1986, y = 0.3, labels="Mean HSI", cex =
0.75)
trellis.unfocus()
Thanks
