list_dec: Create Decoration's Graphs and Store them in a List
In iconr: Graphical and Spatial Analysis for Prehistoric Iconography

Description Usage Arguments Value See Also Examples

Create undirected graphs for each decoration from nodes, edges and imgs dataframes and store the graphs in a list. The join between these dataframes is done on the two fields site and decor. Graph names refer to imgs$idf.
