Dear R Lists,
Can anyone help me add site IDs (site: 1~50) directly to my xyplot. I have 50
sites and collected observations from the sites at 13 different time points. I
want to look at the change of my observations in each site. I was able to make
a graph using xyplot, however, I can't find how to add site IDs within the
graph not adding them in the legend. Overall, I would like to be able to
recognize lines matching respective site IDs.
Here is the code (source: MASS) I used below:
library(lattice)
sps <- trellis.par.get("superpose.symbol")
sps$pch <- 1:13
trellis.par.set("superpose.symbol", sps)
xyplot(CADapt~Date, data= omni.sb08, groups=Plot2,
panel = panel.superpose, type="b"
)
Thank you very much in advance!
Steve Hong
