[R-pkg-devel] Vignette title problem

Dear CRAN

I have made a vignette and followed the instructions for adding a title and
name at the top of the vignette, the title and name appears locally when I
build it from RStudio. However, whenever it gets uploaded to CRAN, it is
not there in the online vignette. The rest of the vignette is fine, just
the title is missing.

Code (works locally to make header in RStudio):
https://github.com/cran/clusterlab/blob/master/vignettes/introduction.Rmd

Vignette (without header):
https://cran.r-project.org/web/packages/clusterlab/vignettes/introduction.html

Hopefully some one can help with this problem.

If you do a local install from the tar.gz file, do you get the title?  I 
think CRAN doesn't normally rebuild vignettes for storage, only for 
checking.

When I try to build the vignette from the source in your link, I get 
this error:

Quitting from lines 40-42 (Untitled.Rmd)
Error: `x` must be a string or a R connection
Execution halted

This comes from the code chunk

library(clusterlab)
synthetic <- clusterlab(centers=1,numbervec=100)

which generates that error on its own.
