I'm trying to create a dotplot with some grouping.
I've been able to create what I want using dotchart (basic graphics), but can't
quite get it using dotplot (lattice). I prefer to use lattice (or ggplot2)
because I think it's a bit easier to control some other aspects of the plot
appearance.
Basically, w/ lattice I've not been able to get the y-axis label to include the
group variable.
I'd like...
A
1
2
B
1
2
3
4
C
1
2
3
I'm getting...
1
2
1
2
3
4
1
2
3
The following example code illustrates....
set.seed(18)
dta <- data.frame(var1=factor(c("A", "A", "B", "B", "B", "B", "C", "C", "C")),
var2=c(1,2,1,2,3,4,1,2,3),
var3=round(runif(9,1,10),1),
plotorder=9:1)
dta
windows(3,3)
dotchart(dta$var3[order(dta$var1, -dta$var2)], groups=dta$var1,
labels=dta$var2[order(dta$var1, -dta$var2)], cex=.75,
gcolor=c("blue", "red", "dark green"),
col=c(rep("blue",2), rep("red",4), rep("dark green",3)),
axes=NULL)
windows(3,3)
dotplot(data=dta, plotorder~var3, groups=var1, col=c("blue", "red", "dark
green"),
scales=list(y=list(labels=dta$var2[order(dta$plotorder)])))
Thanks.
