title: RSelenium couldn't connect to host
body: <p>I wrote a web-scraping program using RSelenium.  It works perfectly on my computer.  When I try to send it to my co-workers, it gives me a "couldn't connect to host" error message. Here is the code I have them run, prior to navigating to the url.  </p>
  
  <p>The error occurs after executing the remDr$open() command, but I'm sure the error is rooted in a earlier line.  When executing this code on my computer, the Java command console pops up after executing the RSelenium::startServer() command.</p>
  
  <pre><code>install.packages("devtools")
  install.packages("stringr")
  install.packages("XML")
  install.packages("RCurl")
  install.packages("RSelenium")
  
  require(devtools)
  require(stringr)
  require(RSelenium) 
  require(XML)
  require(RCurl)
  
  RSelenium::checkForServer(update=TRUE)
  RSelenium::startServer()
  remDr=remoteDriver()
  remDr$open() 
  </code></pre>
  
  <p>Here is the R sessionInfo on the computer that is having trouble running it:</p>
