[R-pkg-devel] No reference output from knitr vignettes

Hi,

After having converted a couple of package vignettes from Sweave to 
knitr, I discovered that the reference output generated by R CMD check, 
i.e., <vignette>.Rnw.log in the check directory, is now empty except for 
the timings.

When doing the conversion I added knitr to DESCRIPTION's Suggests and 
VignetteBuilder fields.  I also added %\VignetteEngine(knitr::knitr) to 
the LaTeX preamble in <vignette>.Rnw.  The vignettes are built OK.

Am I doing something wrong here?
