Thanks very much Deepayan for your helpful replies.
The line in the plot is exactly how I want now (black and on top of the
points [by default, as you say -- I just couldn't see it because it was
same the colour as the points before])
Best wishes

Actually, this is already what you want, so you shouldn't need to do anything.

The order is hard-coded in the panel function:
> plot(augPred(fit))$panel
function (x, y, subscripts, groups, ...)
{
if (grid)
panel.grid()
orig <- groups[subscripts] == "original"
panel.xyplot(x[orig], y[orig], ...)
panel.xyplot(x[!orig], y[!orig], ..., type = "l")
}
You can change it by supplying your own panel function, e.g.
plot(augPred(fit), col.line = "black",
panel =
function (x, y, subscripts, groups, ...) {
panel.grid()
orig <- groups[subscripts] == "original"
panel.xyplot(x[orig], y[orig], ...)
panel.xyplot(x[!orig], y[!orig], ..., type = "l")
})

[R] change fitted line colour in lme() trellis plot?
If I used a groupedData object, if I do fit<-lme(blah) then plot(augPred(fit)) produces a nice trellis plot of the data along with the fitted lines However I find that the lines and the data points are in the same colour (light blue against a medium grey background). Is there a way to make the lines in a different colour (e.g. black)? It would also be nice if the line were plotted after the points so it is visible (I have a lot of points and the line is obscured). I have looked at par(). Thanks very much for any help.
