Re: [R] Replacing plot symbols w/ subject IDs in xyplot()

For plot():
plot(x,y, type = "n")
text(x,y, lab= junk.frm$ID)

This accomplishes the goal of using subject IDs as plot symbols, but I can't seem to get the same result below w/ xyplot(). Is there something different I have to do for xyplot()?

xyplot(y ~ x, type = "n")
text(x,y , lab=junk.frm$ID)
# doesn't work
