title: Why am I getting a syntax error with RSelenium in Docker?
body: <p>I am trying to follow this tutorial <a href="https://cimentadaj.github.io/blog/2018-03-22-rselenium-and-scraping-catalan-educational-data/rselenium-and-scraping-catalan-educational-data/" rel="nofollow noreferrer">RSelenium and scraping</a> as it seems to be just what I am trying to do. Use RSelenium to scrape a Javascript website.</p>
  
  <p>I have installed Docker and all seems good, but I run into problems with the following command:</p>
  
  <pre><code>remDr &lt;- remoteDriver(remoteServerAddr = "localhost", port = 4445L, browserName = "firefox'")
  </code></pre>
  
  <p>which I think is intended to be:</p>
  
  <pre><code>remDr &lt;- remoteDriver(remoteServerAddr = "localhost", port = 4445L, browserName = "firefox")
  </code></pre>
  
  <p>However, both versions return this error:</p>
  
  <pre><code>bash: syntax error near unexpected token `('
  </code></pre>
  
  <p>What am I doing wrong?</p>
  
  <p>Here is the full log:</p>
