## MakeNetworkGeneric.Rmd

This R Markdown document presents code to build a network of datasets from a DataONE member node.  It takes as input a `.csv` file with two columns (a list of users in one column, and a list of datasets in the other), works on the `.csv` table to build a network describing the relationships among datasets in the member node, then calculates statistics of interest for that network. The `.Rmd` file produces two outputs: 

1. A table of networks statistics, saved as a `data.frame` and a `.csv` file.  

2. A `.csv` file with three node characteristics: 

    - Node degree

    - Node modularity class for two different community detection algorithms 

Details about how to run the code are included in the `.Rmd` file.  The `MakeNetworkGeneric.Rmd` file will run as-is, but the analyst will probably want to customize it for the particular network being built.
