Rendering of code chunks in vignettes

[rstub]

Looking at the vignette of dqrng I see several things that are not working:

• The second code chunk gives:

  Error: there is no package called 'dqrng'

  What's the point of making the code in a package vignette executable if the package itself is not available?

• The Second code chunk gives this additional error:

  Error: could not find function "piR"

  That function is defined in the first code chunk. In R Markdown it is standard that such definitions are also available in subsequent code chunks. Is this possible in this interface, too.

• All the C++/Rcpp code chunks are interpreted as R code chunks. These are marked as {r, eval=FALSE, engine='Rcpp'} in the Rmd, which works for the normal vignette rendering. Could these be correctly interpreted as C++/Rcpp here as well?

The second code chunk does not give an error anymore. Closing this issue :)
