df2neo4j: df2neo4j

In brendan-newlon/df2neo4j: What the Package Does (One Line, Title Case)

Description

Write a data.frame directly to nodes in Neo4j.

Usage

load_df_to_neo4j(
  df,
  label,
  Unique_ID_col,
  other_constrain_col = "NONE",
  neo.import.dir
)

Arguments

df	The data.frame with data about your nodes and their properties
label	Use label to indicate what type of node is represented in your df. You can assign one or more labels. For example, if one df contains data about your individual clients while another holds data about your corporate clients, you can label both as clients while also labeling one set as people and the other as organizations: load_df_to_neo4j( individual_clients, label = c("Person", "Client"), Unique_ID_col = "Client_ID", other_constrain_col = c("Email", "Phone") ) load_df_to_neo4j( corporate_clients, label = c("Organization", "Client"), Unique_ID_col = "Client_ID", other_constrain_col = c("Client_Contact_Email", "Client_Contact_Phone") )
Unique_ID_col	Indicate one column that provides a unique ID for each unique node. This could be an ID number or something else that should be unique, such as a personal email address or phone number.
other_constrain_col	Identify any other columns that contain values that should be unique to one node, such as a personal email address. NOTE: If you've accidentally assigned two different IDs where the person's email address is the same, this will throw an error so you can locate the problem row.
neo.import.dir	The directory location of the Neo4j import folder.

Details

Helpful R functions for working with Neo4j graph databases

This function allows you to write a data.frame directly to nodes in Neo4j.

Note: The column names of the df will be used to name the properties. Eg. "Name", "Phone", "Email", "Client_ID"

Value

The function writes a .csv file in your Neo4j database import directory, then loads the data to Neo4j. Once done, the .csv file is no longer needed, and it will be overwritten the next time the function is used.

Examples

load_df_to_neo4j(
   df,
   label = c("Person", "Client"),
   Unique_ID_col = "Client_ID",
   other_constrain_col = c("Email", "Phone")
)
