We can see the plotting options using trellis.par.get(). For example, one
listed parameter is $superpose.line for which we can set col, lty, and lwd.
Load the mlmRev package to obtain the Gcsemv data (used in Lattice book).
One way to set the parameters is
data(Gcsemv, package = "mlmRev")
my.fonts <- list(font = 2,cex = 2)
my.theme <- list(
superpose.symbol = list(col=c(1,3)),
superpose.line=list(col=c(1,3),lwd=c(1,2)),
par.xlab.text = my.fonts,
par.ylab.text = my.fonts
)
xyplot(written ~ course , data = Gcsemv, groups = gender, type = c("p","r"),
par.settings = my.theme,
auto.key = list(lines = TRUE, points = FALSE))
