As far as I know R.rsp doesn't support Rmd vignettes.  I just took a 
quick look at the code, and it appears to support these formats:  .rsp, 
.pdf.asis, .html.asis, .tex, .ltx, .md, .md.rsp.

So you should rename the source file to one of those, or choose a 
different vignette engine.  knitr::rmarkdown is the usual engine to use 
with R Markdown files.
