title: How to open Google Chrome with RSelenium?
body: <p>I am using RSelenium and I want to open and navigate Google Chrome. However, I always get an error when I want to open the browser from R. The following code is used:</p>
  
  <pre><code>library("RSelenium")
  startServer()
  mybrowser &lt;- remoteDriver(browserName = "chrome")
  mybrowser$open()
  
  [1] "Connecting to remote server"
  Error:   Summary: UnknownError
   Detail: An unknown server-side error occurred while processing the command.
   class: java.lang.IllegalStateException
  </code></pre>
  
  <p>The same code works for Firefox. What can I do about it?</p>
