How about this?
library(lattice) xyplot(y ~ x, panel = function(x, y, ...){ panel.xyplot(x, y, ...) panel.lmline(x, y, type="l") })

I am trying to use the Lattice package to produce the same result as I can with the base graphics.
With base graphics I can type:
x <- 1:100 y <- x+rnorm(length(x)) g <- lm( y ~ x ) model.y <- g$coef[1]+g$coef[2]*x
plot(x,y) # a plot of the data lines( x, model.y ) # a plot of the model, superimposed on the first plot
With Lattice graphics I've got this far:
library(lattice) plot1 <- xyplot(y ~ x) plot2 <- xyplot(model.y ~ x, panel = function(x, y) { llines(x=x, y=y) }) print(plot1, more=TRUE, position=c(0,0.5,1,1)) print(plot2, position=c(0,0,1,0.5))
But this just produces two graphs, one above the other. How do I overlay them? What should I be doing in order to get the same result as with the base graphics?
