[R-pkg-devel] Warning Message on Vignettes

Hi,

I am getting following two warnings when I submit my R package (perfectphyloR) to CRAN.

Warning 1: * checking files in 'vignettes' ... WARNING
              Files in the 'vignettes' directory but no files in 'inst/doc':
              'perfectphyloR.html', 'perfectphyloR.html.asis'

Warning 2: * checking package vignettes in 'inst/doc' ... WARNING
              dir.exists(dir) is not TRUE
              Package vignette without corresponding single PDF/HTML:
              'perfectphyloR.html.asis'

I want to make my vignette as a static html vignette (not the PDF). Therefore, I followed this documentation, https://cran.r-project.org/web/packages/R.rsp/vignettes/R_packages-Static_PDF_and_HTML_vignettes.pdf

After including my html vignette (perfectphyloR.html) into the directory 'vignette', I created a file called "perfectphyloR.html.asis" and that file includes following lines:

%\VignetteIndexEntry{R packages: perfectphyloR}
%\VignetteEngine{R.rsp::asis}
%\VignetteKeyword{HTML}
%\VignetteKeyword{vignette}
%\VignetteKeyword{package}

So, I am wondering something is wrong with my .asis file or I am doing any other mistake. Could you help me fix this issue?
