packageURL = "../packages/", reposname = "CRAN")
check_ctv_packages(file, repos = TRUE, …)
repos_update_views(repos = ".", css = "../CRAN_web.css", reposname = "CRAN", …)

further arguments passed to available.packages
or
ctv2html
, respectively.
updateViews
returns an object of class "ctvlist"
containing

of the XML package.
ctv2html
generates a .html

a "ctv"

check_ctv_packages
checks whether the info and packagelist sections of the
.ctv

repos_update_views
reads all .ctv
files in a specified directory, generates
a .html
