I have the following output from pretty():
[1] -2.000000e-01 -2.775558e-17  2.000000e-01  4.000000e-01  6.000000e-01
[6]  8.000000e-01  1.000000e+00
[1] "-0.2"                  "-2.77555756156289e-17" "0.2"                  
[4] "0.4"                   "0.6"                   "0.8"                  
[7] "1"                    


The root cause seems to be here:
[1] -2.775558e-17


(It seems that this is not a problem in all installations.)

You can't expect exact arithmetic.  Using as.character is almost never a
good idea.  I don't think this is a bug, but you should be doing something
more complex if you want to make labels here.
