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

when I launch
kblDB = startGraph("http://localhost:7474/db/data/", username="neo4j", password="1")

it gives me this:
curl::curl_fetch_memory(url, handle = handle) : Failed to connect to localhost port 7474: Connection refused

what is the value for url? Also what is the value of handle?

If we don't know what you are passing to the function there's no way we can ever help you diagnose your error. Some sort of reproducible example (reprex) would allow you to get more meaningful answers. Here's a blog post about creating a reprex:
