Hi JC and Bill,

Thanks a lot for your help. 

I found that Office 2007 and 2010 both have this problem when I choose to save as PDF file in Word program.  If I copy a graph as bitmap file, then everything is ok, but not look as nice as metafile.  I have tried to use other two tools (CutePDF and PDFcomplete), and the PDF files created from these two tools are both fine.  So, it sounds this is due to the PDF conversion within Word program.

Jim,
I have seen this outcome as well with graphs from time to time and
agree with Jean-Christophe that the bug seems to creep in at the
Windows / Office level.  You do not mention your version of Word, but
I have seen this with Word 2000 and Word 2007 (doc and docx) software
and formats, for example.

One other workaround is to *Print* the whole document to PDF, rather
than "Save As".  This would require an (Adobe) PDF driver installed on
your system.

Or as Jean-Christophe suggests, use another output format for pasting
or inserting the picture into Word. I have not had much luck with
graphs in PDF format for insertion, since I have never seen PDF as an
accepted graph format. PNG or BMP (e.g. copy file as bitmap from an R
graphics window) and others work well if you can live without
vector-based flexibility to resize the graph within the document.

Hope that helps.

Bill
