[R] Specifying relative position of text in a plot

[Bill.Venables at csiro.au]

Here is one way.

...
usr <- par("usr")  		# get user coordinates
par(usr = c(0, 1, 0, 1)) # new relative user coordinates

text(0.1, 0.5, "Some text", adj = 0)  # if that's what you want

par(usr = usr)			# restore original user coordinates

...

If you were going to be doing this a lot, you could write a simple
wrapper function to text(...) to incorporate this change to relative
coordinates and back again.

Subject: [R] Specifying relative position of text in a plot


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
up
from the x axis? Thanks.
