How to retrieve hyperlinks in google search using rvest

I am using rvest to get the hyperlinks in a Google search. User @AllanCameron helped me in the past to sketch this code but now I do not know how to change the xpath or what I need to do in order to get the links. Here my code:

library(rvest)
library(tidyverse)
#Code
#url
url <- 'https://www.google.com/search?q=Mario+Torres+Mexico'
#Get data
first_page <- read_html(url)
links <- html_nodes(first_page, xpath = "//div/div/a/h3") %>% 
  html_attr('href')

Which entirely returns NA.

I would like to get the links for each item that appears like next (sorry for the quality of images):

Is possible to get that stored in a dataframe? Many thanks!

Look at the parents a of the h3 nodes and find their href attribute. This ensures you have the same number of links as the main titles, to allow for easy arrangement in a dataframe.

titles <- html_nodes(first_page, xpath = "//div/div/a/h3")

titles %>%
  html_elements(xpath = "./parent::a") %>%
  html_attr("href") %>%
  str_extract("https.*?(?=&)")
