[R] setting key boxes in xyplot

[Steve_Friedman at nps.gov]

I thought I mimicked the coded correctly, but find an error/omission
somewhere in the xyplot function shown below.

> eggs # alligator egg fate

dput(round(eggs, 2), file = "")
structure(list(Year = c(1985, 1986, 1987, 1988, 1989, 1990, 1991,
1992, 1993, 1994, 1995, 1996, 1997, 1998, 1999, 2000), NumEggs = c(323,
1729, 1127, 104, 267, 291, 352, 478, 532, 569, 263, 490, 244,
428, 527, 670), Failed = c(183, 199, 257, 503, 99, 139, 273,

  xyplot(Eggs.p + Fail.p + Mean ~ Year , data = eggs, cex = 0.8, pch = c(2,
5),
         panel = panel.superpose.2, main = "Alligator Nest Fate",

Flooded Eggs",
         legend = list(right = list(fun = grid::textGrob("Mean HSI",
rot=90))), col=(1:3),  type = c("b", "b", "h"),
         key = list(text = list(c("Proportion Hatched R^2 = 0.13,
Proportion Flooded R^2 = -0.23, Mean HSI")),
         col = c("black","red", "green")), columns = 3)


Thanks for the assistance.
