Can't install a package with an error: "Currently it is not possible to install binary packages from a remote repository as root"
<p>I was unable to install a R package through GUI <code>R.app</code> on macOS, using a package installer GUI. In the past, I was able to install it without any problems.</p>

<p>The problem is when I tried to install a package, an error <code>Currently it is not possible to install binary packages from a remote repository as root.</code> occurred. I might not be good at the system-level knowledge, so want to use GUI as I have used it. But what is preventing the GUI from working any longer? Maybe from Yosemite it is no longer working?</p>

<p>And finally, is it still possible to use GUI package installer in this situation?</p>

<h3>UPDATE</h3>

<p>Hmmm... It seems that after updating to 3.3.1 (I used 3.3), the problem has gone away. I can install packages both at User Level and System Level without any problems. I don't know why, but someone can clarify it in case I would face the same problem in the future?</p>
