I have been trying to use this question and this tutorial to get the table and links for the list of available rpackages in cran
Getting the html table
I got that right doing this:
library(rvest)
page <- read_html("http://cran.r-project.org/web/packages/available_packages_by_name.html") %>% html_node("table") %>% html_table(fill = TRUE, header = FALSE)
trying to get the links
When I try to get the links is where I get in trouble, I tried using the selector gadget for the first column of the table (Packages links) and I got the node td a
, so I tried this:
test2 <- read_html("http://cran.r-project.org/web/packages/available_packages_by_name.html") %>% html_node("td a") %>% html_attr("href")
But I only get the first link, then I thought I could get all the href
from the tables and tried the following:
test3 <- read_html("http://cran.r-project.org/web/packages/available_packages_by_name.html") %>% html_node("table") %>% html_attr("href")
but got nothing, what am I doing wrong?
