I had no problem withe your example. The PDF came out just like
the graphic plot, with DELTA follow by D, whether I view it
using acroread or gv. My sessionInfo:

sessionInfo()
R version 2.11.0 (2010-04-22) 
i486-pc-linux-gnu 

locale:
 [1] LC_CTYPE=en_GB.UTF-8       LC_NUMERIC=C              
 [3] LC_TIME=en_GB.UTF-8        LC_COLLATE=en_GB.UTF-8    
 [5] LC_MONETARY=C              LC_MESSAGES=en_GB.UTF-8   
 [7] LC_PAPER=en_GB.UTF-8       LC_NAME=C                 
 [9] LC_ADDRESS=C               LC_TELEPHONE=C            
[11] LC_MEASUREMENT=en_GB.UTF-8 LC_IDENTIFICATION=C       

attached base packages:
[1] stats     graphics  grDevices utils     datasets  methods   base

which is the same as yours (except that I'm using a slightly
earlier version of R, and on i486 rather than x86_64. Debian
Etch by the way).
