Installed Rneo4j. it gives me and error when I use it. Can anybody help?

Hi,

Welcome to the community. First off, if you could change your question title to be slightly more informative, it will help ensure that you get the eyes you need to help you out!

From our Writing r coding questions guide;

For many, your title will be the only thing they see before deciding whether or not to move on. Your title should summarize your query, while being as short, clear, and compelling as possible.
If you are unclear about this, here’s a nice SO discussion with examples of good and bad titles .

Are you using Neo4j by chance?
