[R] how to specify point symbols in the key on a lattice dotplot
I am making a dotplot with lattice, as follows:
dd %>% dotplot( segment ~ transit_time, groups = impact, data = .,
as.table = TRUE,
pch = 16:17,
cex = 1.8,
scales = list(cex = 1.4),
auto.key = TRUE)
impact is a factor with two levels.
They key shows 2 open circles, one of each color of my two
plotting symbols, one for each group. I would like the
symbols in the key to match the plotting characters in the graph: 16
(filled circle) for one group and 17 (filled triangle) for the second
group. How would I do that? I have not had any success with supplying
arguments to auto.key, simpleKey, or key. Guess I'm not understanding
the syntax.
Thanks.

Add: key = list(points=16:17) Into the dotplot section possibly without the autokey On Fri, 13 Sep 2024, 08:19 Christopher W.

Guess I'm not understanding > the syntax.Specifying key = list(...) will work, but the shortcut is to add par.settings = simpleTheme(pch = 16:17, cex = 1.8) That way, you don't need to specify the parameters anywhere else. -Deepayan> Thanks. > > --Chris Ryan > > -- > Agency Statistical Consulting, LLC > Helping those in public service get the most from their data. > www.agencystatistical.com > > Public GnuPG email encryption key at > https://keys.openpgp.org > 9E53101D261BEC070CFF1A0DC8BC50E715A672A0 > > ______________________________________________ > R-help at r-project.org mailing list -- To UNSUBSCRIBE and more, see > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide https://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code.
