I recently learned about the R package,
pkgdown, an R package that provides functions that make it easy to build a website from an R package on Github.
I decided to build a site for my package
qtl2pleio. The site is here. It features a documentation page for each function in the package.
pkgdown is extremely easy.
devtools::install_github("r-lib/pkgdown") library(pkgdown) build_site()
pkgdown is used by more than 1300 packages, according to its README file.
