Hi Ivo
If you want to add lines, text etc you can do that by a lattice panel
function included in it would be panel.contour
something like (untested)
contourplot(...
panel = function(x,y, etc,...){
panel.countorplot(x,y, etc)
panel.lines(x,y,...)
panel.text(....)
}
)
and see also
library(lattice)
names(trellis.par.get())
and delve into the names that come up that are applicable
See the help page
? panel.lines which should cover most of what you need.
Remember that you may have to look at
? grid::gpar for fine tuning of the arguments
Just finished a plot with panel.segments
panel.segments(xlocs - medsbar.len, meds,
xlocs + medsbar.len, meds,
lineend = 1, # grid gpar call for line ending
lwd = 5,
col = 2)

Subject: [R] combine trellis lattice contour plot with simple plot()
points() and text() commands?
can I add ordinary graphics commands to a contourplot? my naive
attempts are telling me that plot.new() has not yet been called when I
try to add text(1,1,"hi") or points( c(0,1), c(1,0) )?
[or do I need to rewrite another contourplot with the old graphics
system. the basics are probably looking at adjacent points,
pretending that they are linear, and mark where a line between them
intercepts the level, and then hope that some sanity prevents me from
connecting disconnected levels. not my plan...]
