Error in initialize(...) : unused argument (is_V4 = TRUE) ==> "neo4j_api$new()" don't understand the argument

[medseddik1999]

Hello , I have a issue , when I run :

`install_github("davidlrosenblum/neo4r@4.x")
library(neo4r)
packageVersion('neo4r')

0.2.0

con2neo4j <- neo4j_api$new(url = "server http url",
user = "neo4j",password = "my_paasword" ,db="graph.db",isV4 = TRUE) `
or

con2neo4j <- neo4j_api$new(url = "server http url",
user = "neo4j",password = "my_paasword" ,db="graph.db",is_V4 = TRUE)

or

con2neo4j <- neo4j_api$new(url = "server http url",
user = "neo4j",password = "my_paasword" ,db="graph.db",isv4 = TRUE)

I have this error :
>Error in initialize(...) : unused argument (is_V4 = TRUE)

and the only way to have a connection I run
con2neo4j <- neo4j_api$new(url = "server http url",
user = "neo4j",password = "my_paasword" ,db="graph.db") without is_V4=TRUE
but a lot of important method don't work as get_labels , get_relationship and I have this error :

Error in if (con$is_V4 == TRUE) { : argument is of length zero.

I have a MacBook and I tried the code in Rstudio cloud and is always a same problem

You can always run the cypher statement behind those things. Some of the function have been deprecated. E.g. call db.indexes is now show constraints. Is_V4 is not needed and was removed over a year ago.

library(devtools)

Loading required package: usethis

install_github("davidlrosenblum/neo4r")

Skipping install of 'neo4r' from a github remote, the SHA1 (4de7ea2) has not changed since last install. Use `force = TRUE` to force installation

library(neo4r) con1 <- neo4j_api$new(url = "http://localhost:7474",user="neo4j",password=“xxxx",db="hcanalytics")

[1] "Found Neo4j 4.x"

con1$ping()

[1] TRUE
