I am trying to start my graph from Rstudio on Mac OSx, installed RNeo4j via devtools on (for R version 3.1.2)
and i received the following error:
"Error in function (type, msg, asError = TRUE) : Failed connect to
localhost:7474; Connection refused"
Are you using Neo4j 2.2? If so, you might need to specify the username and password (which you can set by going to
localhost:7474 in your browser if you haven't already).
