Utility functions for adding growth standard bands to ggplot2/lattice plots

Description

Utility functions for adding growth standard bands to ggplot2/lattice plots

Usage

panel.zband(x, z = -3:0, color = "green", alpha = 0.25)

geom_zband(obj, x, z = -3:0, color = "green", alpha = 0.25)

Arguments

x	range on x axis that should be covered by bands
z	z-scores at which to draw bands (only need to specify on one side of zero)
color	color to use for bands
alpha	transparency of the bands
obj	ggplot2 object to add z bands to

Examples

## Not run: 
library(ggplot2)
p <- ggplot(data = cpp, aes(x = jitter(agedays), y = haz))
geom_zband(p, x = seq(0, 2600, by = 10)) +
  geom_point()

library(lattice)
xyplot(haz ~ jitter(agedays), data = cpp,
  panel = function(x, y, ...) {
    panel.zband(x)
    panel.xyplot(x, y, ...)
  },
  col = "black", alpha = 0.5
)

## End(Not run)
