Thanks for all of the suggestions. The key key here seems to be using the
"par" function to change the coordinate system like so
plot(rnorm(100), rnorm(100))
op <- par("usr")
par(usr = c(0, 1, 0, 1))
text(0.5,0.5,"TEST")
par(usr = op)

See ?par, entry "usr". Either set a new coordinate system and use it, or
convert 1/10 to user coordinates.
In R-devel (2.7.0 to be) this is easier:
text(grconvertX(0.1,"npc"), grconvertY(0.5, "npc"), "some text")
cnvrt.coords() in package TeachingDemos does something similar (although
it d
Try this:
plot(rnorm(100))
text(diff(par("usr")[1:2])/10, sum(par("usr")[3:4])/2, labels="Test")

What is the simplest way to specify the location of text in a scatter plot
(created using the plot function) in relative terms rather than specific x-y
coordinates? For example, rather than putting text at (300,49) on a plot,
how do I put it 1/10 of the way over from the y axis and 1/2 of the way
11 matches
