Dear R-helpers,
How do I tell panel.polygon what greoup and panel it applies to whithin
xyplot(y ~ x | c, groups = g
panel = function(x, y, groups, ...){
panel.polygon(x = xpol[c, g], y = ypol[c, g], default.units
= 'native')
panel.xYplot(x, y, groups, ...)
llines(x = c(1, 6), y = c(-24.283333, 35.941667), lwd = 2, lty
=
3, col = 4)
}
x[c, g] and y[c, g] describe the polygon I want plotted for group g
in panel c.
