Error in initialize(...) : unused argument (is_V4 = TRUE)

[cassiodorus]

Well, I suppose this is something I have screwed up, but I am using R 4.2.1 (2022-06-23 ucrt), Rstudio 2022.07.1, Neo4j 4.4.5, Windows 11 Pro. Installing the neo4r from the "official" CRAN I cannot get it to behave reasonably.

con <- neo4j_api$new(
url = "http://localhost:7687",
user = "neo4j",
password = ""
)
con$ping()
[1] 200
con$get_version()
NULL
con$get_relationships()

A tibble: 1 x 1

labels

1 list(oidc_providers = list())

Return code 200 sounds good, but nothing further works. So I installed your fork (I have Rtools installed) and get:

library(neo4r)
con <- neo4j_api$new(

• url = "http://localhost:7687", 
  

• user = "neo4j", 
  

• password = "<real password>",is_V4 = TRUE
  

• )
  Error in initialize(...) : unused argument (is_V4 = TRUE)

It looks to me as though the installation worked, but I'm not a developer. I do not understand how is_V4 can be an unused argument when ?neo4j_new returns with Method new() Usage neo4j_api$new(url, user, password, db = "neo4j", is_V4 = TRUE)

I would greatly appreciate your help. This is part of an open source project focusing on the NLM MeSH codes.
