Try this:

 plot(1:10)

 # par("usr") defines the x/y coordinates of the plot region
 usr <- par("usr")

 # Upper Left Hand Corner
 text(usr[1], usr[4], "test", adj = c(0, 1))

 # Lower Left Hand Corner
 text(usr[1], usr[3], "test", adj = c(0, 0))

 # Lower Right Hand Corner
 text(usr[2], usr[3], "test", adj = c(1, 0))

 # Upper Right Hand Corner
 text(usr[2], usr[4], "test", adj = c(1, 1))



See ?par and ?text for more information including the 'adj' argument to
text().
