R help - Sep 2016 - Add annotation text outside of an xyplot (lattice package)

Dear list,

Just wonder if there is a way to add annotation text outside an xyplot,
(e.g. the bottom of the plot). the panel.text seems only add text within
the plot. Thanks.

Hi,

Yes, you can use "latticeExtra" package and use a text layer on top of
your
current chart.

Thanks,
Carlos Ortega

Hi,

one possible solution is to use ltext().

ltext(xcoord, ycoord, label="TEST", adj=c(0.5,0.5))

You have to know or to find out best fitting coordinates.

Via adj you can control, if the text should adjust left, center or right
to the coords, and above, center or bottom of them.

HTH,

No.

ltext/panel.text plots text *within* panels; IIUC, the  OP requested
text outside the plots. For that see the details for "main" and/or
"sub" in ?xyplot. I think it could also be done more flexibly via a
legend or a key with a title but no content -- again, see the Help
page -- but haven't tried it.

Cheers,
Bert

You can find an example of annotating lattice graphics with text anywhere
on the graphics device using the pagenum package.  See the vignette here:

https://cran.r-project.org/web/packages/pagenum/vignettes/pagenum.html

The pagenum package uses the grid package to add viewports for the
annotation.  The R code showing how this works is here:
