If it does NOT have to be specifically Doulos SIL, some of the standard 
Windows fonts appear to include IPA characters, which means that you 
might just be able to use the PDF device provided by the Cairo package ...

library(Cairo)
CairoPDF()
barplot(c(1,2,3,4,5),
         names=c("\u{0251}","\u{0252}","\u{0253}","\u{0254}","\u{0255}"))
dev.off()

If it DOES have to be specifically Doulos SIL, PDF output is possible, 
but it's a bit more work (see 
http://www.stat.auckland.ac.nz/~paul/R/PDF/pdfEncoding.html).  If you 
want to follow this path, contact me directly and I can email you some 
code and files to show how it's done.
