Dear Kristi,
You could do something like this.
ggplot(dat1, aes(x = factor(site), y = Present)) +
geom_boxplot(aes(colour = layer)) +
geom_line(data = dat2, aes(group = 1, y = present)) +
geom_point(data = dat2, aes(y = present))
Note that
- ggplot provides no second axis
- the boxplots di
Hi Kristi
Jim has given you 1 non ggplot2 solution here is one from lattice
panel.average is a line so added a line for points
# convert site to a factor
dat1$Site = factor(dat1$Site)
datav <- aggregate(Present ~ Site, dat1,mean)
datav
diff(datav[,2]) # test
bw1 <-
bwplot(Present~Site,dat
