You'll need a custom panel function. It would also help if you
provided a reproducible example:
xyplot (
SnowLineElevation ~ Year | Model,
data = data,
panel = function(x, y, col, ...) {
col <- ifelse(panel.number() == 1, "red", "green")
panel.xyplot(x, y, col = "blue", ...)
panel.loess(x, y, col = col)
},
ylim = c(0,1800),
pch = 21,
xlab = 'Year',
ylab = 'Snowline Elevation [m]'
)
Alternatively, you can use the group argument in conjunction with the panels:
xyplot(SnowLineElevation ~ Year | Model, data, groups = Model, type =
c("p", "smooth"))
if you want the points and the lines to be the same color.
