[R] pdf files, change in content

[p.b.pynsent]

There seems to be something different about pdf files generated under 
RAqua (1.8.1).
I am losing text.
I am not sure when things changed but, on Carbon 1.7, when files were  
'drag and dropped'  onto another application they worked fine. Now the 
text is lost but the graphics are intact. However the text is there 
when viewed with Acrobat.
On the other hand, if I output to an eps file and then use the 
Perl/ghostscript function eps2pdf,  the pdf file generated works as I 
would expect.

The programme I have used as a test is:

oldpar <- par(no.readonly=TRUE)
postscript("test.eps", onefile=TRUE, bg = "white",
	family= "Times", paper = "A4", horizontal = TRUE)
par(omi=c(0.5,0.5,0.5,0.5))
plot(1:10,type = "p")
text (5, 5, labels = "Hello world", cex = 1.5)
par(oldpar)
dev.off()
#
oldpar <- par(no.readonly=TRUE)
par(omi=c(0.5,0.5,0.5,0.5)
pdf("test.pdf",width = 27/2.54, height = 18.4/2.54, bg = "white", 
onefile = TRUE,family = "Times")
plot(1:10,type = "p")
text (5, 5, labels = "Hello world", cex = 1.5)
par(oldpar)
dev.off()


I should be most grateful for any suggestions for a remedy.
