+   cql='MERGE (n:TestNode {name:row.name, value:toFloat(row.value)})',
+   toImport=nodes
+ )

Note

I set all of the environment variables this way:

Sys.setenv(HOME="C:/Users/balter")

Sys.setenv(
  CONTAINER=neo4j_cont,
  NJ_VERSION="4.3.4",
  NJ_HTTP_PORT=7474,
  NJ_BOLT_PORT=7687,
  ### Authorization
  ### ---set to 'none' if you want to disable authorization
  NJ_AUTH="neo4j/n4jpw",  
  ### APOC download
  ### --- should already be installed in the docker image
  # export NJ_APOC=https://github.com/neo4j-contrib/neo4j-apoc-procedures/releases/download/4.0.0.2/apoc-4.0.0.2-all.jar
  # export NJ_APOC=https://github.com/neo4j-contrib/neo4j-apoc-procedures/releases/download/3.5.0.7/apoc-3.5.0.7-all.jar
)

Sys.setenv(
  ### Change the location of the Neo4j directory
  NJ_HOME=file.path(Sys.getenv("HOME"), "neo4j_home"),
  NJ_IMPORT=file.path(Sys.getenv("HOME"), "neo4jImport"),
  NJ_PLUGINS=file.path(Sys.getenv("HOME"), "neo4j_home", "neo4jPlugins"),
