R help - Dec 2007 - odfWeave error

hello all,
I trying to use the package 'odfWeave'
and I get the follow error:



###  error message
#############################################################
...
  Removing content.xml

  Post-processing the contents
Error in .Call("RS_XML_Parse", file, handlers, as.logical(addContext),
:
  Error in the XML event driven parser for content_1.xml: error parsing 
attribute name



The piece of the code is:

###  code
############################################################
...

<<makeGraph, echo=T,
results=xml>>fileplot='C:\\DADOS\\tmp\\plotx.emf'
win.metafile(fileplot)
plot( rnorm(300), col='red', t='l', lwd=2 ); grid()
dev.off()
@

<<insertGraph, echo=T, results=xml>>odfInsertPlot(file=fileplot,
height=5, width=5 )
@

???? This chunk is pure R code and shouldn't output anything directly in
the output file. Since you are telling "echo=T', whatever is output by
your code is sent to your output file, and since you assert
"results=xml",this output is interpreted as xml ; since this isn't
XML,
your're getting guff from the XML interpreter.

I'd rather do :
<<makeGraph, echo=FALSE>>invisible({
# Whatever you did ...
})
@
instead. Your second chunk :
> <<insertGraph, echo=T, results=xml>>>
odfInsertPlot(file=fileplot, height=5, width=5 )
> @
should insert your plot in the output file.

BTW : Windows (enhanced) metafile are Windows-specific. As far as I can
tell, recent versions of Office and OpenOffice.org correctly render
Encapsulated Postcript files, thus freeing you from another Windows
demendency. Unless you *have* to have an EMF output (it happens, I know
...), youd'better use use this format directly.
