title: Failed connect to localhost:7474; Connection refused. Where is the neo4j-server.properties file?
body: <p>I am trying to start my graph from Rstudio on Mac OSx, installed RNeo4j via devtools on (for R version 3.1.2)
  "startGraph("<a href="http://localhost:7474/db/data/" rel="nofollow">http://localhost:7474/db/data/</a>")"
  and i received the following error:</p>
  
  <blockquote>
    <p>"Error in function (type, msg, asError = TRUE)  :    Failed connect to
    localhost:7474; Connection refused"</p>
  </blockquote>
  
  <p>It looks like it is an Error code: <code>ERR_CONNECTION_REFUSED</code>
  searching online, they recommend to modify conf/neo4j-server.properties file.
  But cannot seem to find the file to correct it.</p>
