I believe the problem is caused by a recent update of WebKit, possibly the one coming with Safari 5.1
I have (at least for now) been able to construct a workaround.

In the file R.tmbundle/Support/tmR.rb there is a line

stdin.puts(%{formals(pdf)[c("file","onefile","width","height")] <- list("#{tmpDir}/Rplot%03d.pdf", FALSE, 8, 8)})

which I have replaced with

stdin.puts(%{formals(pdf)[c("file","onefile","width","height")] <- list(paste(tempfile(pattern="Rplot",tmpdir="#{tmpDir}"),"-%03d.pdf",sep=""), FALSE, 8, 8)})

generating file names with a random part.
This avoids the non refresh of the pdf files containing the plots.
