Downloading files from ftp with R
<p>I am trying to get files from this FTP</p>

<p><a href="ftp://ftp.pride.ebi.ac.uk/pride/data/archive/2015/11/PXD000299/" rel="noreferrer">ftp://ftp.pride.ebi.ac.uk/pride/data/archive/2015/11/PXD000299/</a></p>

<p>From there, I need only the files starting with the .dat extension. But there are other files that I am not interested in.</p>

<p>I want to avoid downloading each one at a time, so I thought in creating a vector with the names and loop over them. </p>

<p>How can I download only the files I want?</p>

<p>Thanks</p>

<p>EDIT:
I have tried doing the following</p>

<pre><code>downloadURL &lt;- "ftp://ftp.pride.ebi.ac.uk/pride/data/archive/2015/11/PXD000299/F010439.dat"
download.file(downloadURL, "F010439.dat") #this is a trial using one file
</code></pre>

<p>And after a few seconds I get the following error:</p>

<pre><code>trying URL 

    'ftp://ftp.pride.ebi.ac.uk/pride/data/archive/2015/11/PXD000299/F010439.dat'
