Inline graphics with Rweave/Sweave, OS X

[Kevin Middleton]

LyXers -

This may be more of an R question than a LyX question, but I thought  
I would try lyx-users first.

Following the instructions on the wiki (http://wiki.lyx.org/LyX/ 
LyxWithRThroughSweave), I successfully setup Rweave (with an small OS  
X caveat, see below). Including R graphics as floats works fine, but  
I can't figure out how to get graphics included inline. I don't even  
know if this is possible. Using the Insert -> Graphics dropdown  
brings up a dialog box -- so nowhere to put the Rweave code.

I also tried putting \includegraphics in an ERT box with the sweave  
code inside the {}, but it goes looking for a file called  
<<label=fig1,fig=T,echo=F>>=plot(1:10)@. Is there some way to wrap  
the Rweave code?

On a separate note, I'm running LyX 1.4.4 in OS X. Starting LyX from  
the LyX.app bundle and then trying to view PDF generates the  
following error: "an error occurred whilst running Rweave  
'testfile.nw'". However, if LyX is started from the command line with  
"/Applications/LyX.app/Contents/MacOS/lyx", then Rweave works fine. I  
was going to add this to the LyxWithRThroughSweave wiki page as a  
note. But could another OS X user confirm this behavior for me?

Thanks,
Kevin
