vertex.id not being recognized as numeric in vertex.spells

[tedmoorman]

I'm trying to replicate the results here. For some reason, when using the networkDynamic function, I receive the following error:

Error in networkDynamic(thenetwork, edge.spells = PHDynamicEdges, vertex.spells = PHDynamicNodes) : 
  vertex.spells requires the vertex.id column to be numeric

I explicitly import vertex.id as a numeric column. So, it's not clear why I'm getting this message.

Here is the output from my console, including the output from sessionInfo():
console-output-from-temporal-network-analysis-with-r.txt

Here is the R code I'm using:
temporal-network-analysis-with-r.R.txt

Here are the csv files downloaded from the aforementioned website:
TNAWR_DynamicNodes.csv
TNAWR_DynamicEdges.csv
TNAWR_StaticEdgelist.csv
TNAWR_VertexAttributes.csv

Update: I had to go the route of a network list to get everything to work for me. The example here was very helpful. I'm not sure if this is ideal though ...
