Tor Browser with RSelenium in Linux/Windows
<p>Looking to use RSelenium and Tor using my Linux machine to return the Tor IP (w/Firefox as Tor Browser). This is doable with Python, but having trouble with it in R. Can anybody get this to work? Perhaps you can share your solution in either Windows / Linux.</p>

<pre><code># library(devtools)
# devtools::install_github("ropensci/RSelenium")
library(RSelenium)

RSelenium::checkForServer()
RSelenium::startServer() 

binaryExtension &lt;- paste0(Sys.getenv('HOME'),"/Desktop/tor-browser_en-US/Browser/firefox")
remDr &lt;- remoteDriver(dir = binaryExtention)

remDr$open()
remDr$navigate("http://myexternalip.com/raw")
remDr$quit()
</code></pre>

<p>The error <code>Error in callSuper(...) : object 'binaryExtention' not found</code> is being returned.</p>

<p>For community reference, this Selenium code works in Windows using Python3:</p>

<pre><code>from bs4 import BeautifulSoup
from selenium import webdriver
from selenium.webdriver.firefox.firefox_profile import FirefoxProfile
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary

from os.path import expanduser # Finds user's user name on Windows

# Substring inserted to overcome r requirement in FirefoxBinary 
binary = FirefoxBinary(r"%s\\Desktop\\Tor Browser\\Browser\\firefox.exe"  % (expanduser("~")))
profile = FirefoxProfile(r"%s\\Desktop\\Tor Browser\\Browser\\TorBrowser\\Data\\Browser\\profile.default" % (expanduser("~")))

driver = webdriver.Firefox(profile, binary)
driver.get('http://myexternalip.com/raw')   
html = driver.page_source
soup = BeautifulSoup(html, "lxml") # lxml needed

# driver.close()

# line.strip('\n')
"Current Tor IP: " + soup.text.strip('\n')
