title: R Pull From FTP Starts Failing
body: <p>Recently had this issue crop up. I pull from an FTP on a bi-monthly schedule into R using a URL string as such:</p>
  
  <p><code>url &lt;- "ftp://User:Pass@ftp.myftp.com/"</code></p>
  
  <p>I use RCurl syntax to pull fill names and then loop through each name, pulling with <code>read.csv</code> with a URL as such:</p>
  
  <p><code>myData &lt;- read.csv("ftp://User:Pass@ftp.myftp.com/mycsv.csv")</code></p>
  
  <p>This worked two months ago, but has started failing today. It <em>could</em> potentially be something has changed in my FTP, but if I drop the above URL in an internet browser, it prompts me to download the file.</p>
  
  <p>Python is able to pull the file, so I feel like I am left with something has changed in R, which I have since updated to 3.4.2 and update RStudio to the current version.</p>
  
  <p>The specific error I get is:</p>
  
  <pre><code>Error in file(file, "rt") : cannot open the connection
  In addition: Warning message:
  In file(file, "rt") : InternetOpenUrl failed: ''
  </code></pre>
  
  <p>I'm going to attempt to install a downgraded version of RStudio and R to what was 2 months ago to see if this solves it. But in the mean time, any ideas? Is this happening for anyone else? It could even by my IT department potentially putting up some kind of firewall. Really scratching my head here.</p>
  
  <p>Thanks in advance.</p>
  
  <p>EDIT: Looks like <code>fread</code> from <code>data.table</code> succeeds. I don't have a clue why <code>read.csv</code> has started failing, however.</p>
