As I wrote above, each gray box with "Chunk n" inside has a unique number visible. I see this unnamed-chunk as the name for the first figure. It's in the /figure subdirectory as unnamed-chunk-7.1.pdf Because that figure is in what LyX shows as Chunk 8 I have no idea where knitr comes up with unnamed.
It turns out that the unnamed-chunks were remnants left after I epxlicity named the chunks. Deleting the unnamed ones did not affect the document becaues it is the named chunks that are used. Thanks for all the guidance, Rich
