title: R - error installing package - Error in curl::curl_fetch_memory(url, handle = handle) : Couldn't connect to server
body: <p>I am trying to install the BTYplus package in R.</p>
  
  <pre><code>devtools::install_github("mplatzer/BTYDplus", dependencies=TRUE)
  library(BTYDplus)
  demo(package="BTYDplus")
  </code></pre>
  
  <p>But it gives me the following error:</p>
  
  <blockquote>
    <p>Downloading github repo mplatzer/BTYDplus@master

  <p>Did anyone had a similar issue when installing packages on R?</p>
