Why do you expect this to be vectorized when the help page clearly says 
otherwise?  See

      adj: one or two values in [0,1] which specify the x (and
           optionally y) adjustment of the labels.  On most devices
           values outside that interval will also work.

What is wrong with two or more text() calls?

NB: library(fortunes); fortune("WTFM") applies.
