Not sure since you have not provided a reproducible example and not
really defined what "annotations" means.
By annotations, I mean that I want to draw an object (set of
poiygon() elements that make up a genomic sequence logo), anchored
at points along the y-axis of the levelplot, on the left side of the
levelplot.
I can't provide a "reproducible" example without adding a large set
of files to this email, which will not get through the list. The
graph itself is mostly fine; the code I provided in the previous
email renders like so:
http://www.flickr.com/photos/alexreynolds/3496072932/sizes/o/
On that graph, I would like to draw polygon() elements at various
points along the left edge of the levelplot. Does this make more
sense?
Yes. Unfortunately, I have no experiences with sticking polygons on
axes. If you could live with the labels of your particular items, then
this example was modified from the ones on the help page for
latticeExtra::dendrogramGrob.
levelplot(x[, col.ord],
aspect = "iso",xlab="",ylab="",
scales = list(x=list(draw=F), y= list(at=c(1,10,15))),
colorkey = FALSE,
legend =
list(right =
list(fun = dendrogramGrob,
args =
list(x = dd.col, ord = col.ord,
side = "right",
size = 10))))
There is a panel.polygon function but my reading of Sarkar's Lattice
book suggests that it would only draw within a plotting region. I
don't have Murrell's Grid Graphics, which I suspect may contain the
answers.
Unfortunately, it's not clear from the example or help description
how I would go about that.
The example to which I used after some guesswork, or another?
