extractVignettes: Extract pdf vignettes from local package repository
In biocViews: Categorized views of R package repositories

These functions extract pdf or HTML files from the inst/doc subdirectory of R source packages archives (.tar.gz) found in a local package repository.

All pdf files found in inst/doc will be extracted. With extractHTMLDocuments, all HTML files except index.html will be extracted. Only source package archives will be processed. The extracted pdf or HTML files will be extracted under destDir and will be found in PKGNAME/inst/doc/.

Prior to extraction, all pdf files in destDir/PKGNAME/inst/doc will be removed.
