Were element nodes removed from clustering? #18

Closed mooreek closed 5 years ago

mooreek commented 5 years ago

The element nodes are colored according to element cluster, but when I look at the node clustering and centrality table elements are not included in the table. I'm guessing this does not affect the linear analyses?

That elements weren't appearing in the table was a bug; fixed now. That said, this is not relevant to linear models. By definition, elements are not part of any linear models - the purpose of models is to study the minerals only. Elements cannot be included for pretty straightforward reasons - they possess entirely different attributes from minerals, i.e. there is not a maximum age, a distribution of of electronegativities, number of localities, etc. In addition, generally each type of node is analyzed separately in bipartite networks, often for reasons like this.

Great, thanks for the clarification. I was worried that if the elements were left out the clusters would change somehow, but that is clearly not an issue.
