R Shiny reactive environment error when building Apps using Neo4j graph data

Asked 2019-Mar-12 at 08:44

I am building an interactive Shiny app using Neo4j graph data by using RNeo4j package to connect Neo4j with R.

The app contains a table showing properties of graph data pulled from Neo4j, users can view and change table content (properties of graph data). The changes can be written back to Neo4j as an update of graph data properties. This function can be completed using updateProp & getOrCreateNode functiona in RNeo4j package.

However, I have a reactive error.

Below is my code:

As you said the last part of your code caused the problem. The reason behind is that you use reactives in this code chunk. That is you use input$category_rows_selected, input$category_status and input$status which do not have a fixed value but depend on your interaction with the app.

Depending on what you want to do you have basically 2 options:

Include the code chunk in isolate. In this case, however, your code will never be updated when you change the respective inputs.
Include the code chunk in observe. In this case whenever either of the inputs (as listed above) change its value, this code will be executed. If you want your code chunk to run only if some of the inputs change you can isolate the inputs you do not want to take a dependency on.

For instance this code will be executed whenever input$category_rows_selected or input$category_status change but not if input$status change because it is wrapped in isolate:

QUESTION

Generating a list of edges in neo4j from a variable length path

Asked 2018-May-31 at 21:29

I am trying to generate a list of edges to read into an R dataframe for use in the vizNetwork package. This has to be, in its most simple format, as a table with 2 columns, "from" and "to".

In the neo4j console, the default query that pops up pretty much illustrates the type of query I am trying to run in that a starting point is specified then the resulting chain is the graph I'm interested in.

The query that is run is match (n:Crew)-[r:KNOWS*]-(m) where n.name='Neo' return n as Neo,r,m and this returns a graph showing the chain of relationships and also a table that I have included below.

Each row you want to return is 1 edge. So to get the return you want, just match on the edge and Neo4j will create a row for every valid occurrence of that pattern.

Your error can happen if you accidentally leave some information out of your startGraph() call. Make sure you have /db/data/ on the end of your graph's url. (If this isnt the case then please post your startGraph command you used).

QUESTION

I want to return the edge list of a a path using cypher and neo4j - how to do it?

Asked 2017-May-01 at 05:46

I have a Neo4J db that I query e.g. to obtain the shortest path between E and F (but it could be any sub graph of the database). I do this using the RNeo4J driver in R.

I would like to return the path(s) as an edge list to R using Cypher so that I can use use the edge list directly to create an Igraph object and plot it or analyze it.

I'm new to Cypher, but have been trying something in the line of the query below using the browser:

This should get the names of the start and end nodes of every relationship in the shortest path, in path order:
