title: how do you use ftps in RCurl
body: <p>I need to get some files from the ftp servers. In my old instance I was using sftp and it was working. I found out that this instance dont support sftp. </p>
  
  <p>This was my syntax to get sftp using RCurl:</p>
  
  <pre><code>url&lt;-c("sftp://192.168.101.3/data/files.csv")
  x&lt;-getURL(url, userpwd="userid:passwd", connecttimeout=60)
  </code></pre>
  
  <p>I tried to replace sftp with ftps, did not work. Does anybody know the RCurl ftps syntax?</p>
  
  <p>I also did this:</p>
  
  <pre><code>url&lt;-c("ftps://userid:passwd@/192.168.101.3/data/files.csv")
  x&lt;-getURL(url, connecttimeout=60)
  Error in function (type, msg, asError = TRUE)  : couldn't connect to host
  </code></pre>
