Hey @Ali, You can use the rvest package to do the same.

You can try this:

library(purrr)
library(rvest)
library(xml2)
url_base <- "https://cran.r-project.org/web/packages/available_packages_by_name.html"
map_df(1:1, function(i){
page <- read_html(sprintf(url_base,i))
data.frame(IssueID = html_text(html_nodes(page,"a")))
    }) -> packages
