I am using RStudio to create and run the Neo4j graph, and it suddenly started the client error: (400) Bad Request when I try to clear the graph.

clear(graph)
You are about to delete all nodes, relationships, indexes, and constraints from the graph database. Are you sure? Y/N
1: Y
Error: client error: (400) Bad Request

Graph version is
< Graph >
$version
[1] "2.3.0"

RStudio is Version 0.99.489

Please help.

What version of RNeo4j are you on? You can check with:

packageDescription("RNeo4j")["Version"]

There was a breaking change introduced in Neo4j 2.3; it's been fixed in RNeo4j 1.6.1. I don't have 1.6.1 on CRAN yet but you can get it through GitHub. First uninstall RNeo4j, restart R, and then use install_github:

devtools::install_github("nicolewhite/RNeo4j")

Thanks. I have 1.6.1 RNeo4j now, but when do install_github, it gives me 401 error:

devtools::install_github("nicolewhite/RNeo4j")
Downloading GitHub repo nicolewhite/RNeo4j@master
Error in download(dest, src, auth) : client error: (401) Unauthorized

What am I doing incorrect?

I just got it on CRAN. Can you try with install.packages?

install.packages("RNeo4j")

Sorry for the late reply. I could not get it working, so I am now working directly with Neo4j-shell writing Cypher queries. Thank you for your help, Nicole.
