Hi all,
Is there a way to create a multilayer network from a group of data.frames?
This would make it very easy to import data to create multigraphs in
graph-tool. This is possible for example in igrap library and for MuxViz in
R( https://github.com/manlius/muxViz).
In Muxviz, for example, one can create a multilayer network using three
data.frames. I copy some of the explanation below from their documentation:
### Node list
One df with following columns :
- nodeID: [mandatory] numerical integer id to identify each node
- nodeLabel: [optional] string specifying the label attribute
- nodeX: [optional] float value specifying the Cartesian coordinate x
for the layout
- nodeY: [optional] float value specifying the Cartesian coordinate x
for the layout
- nodeLat: [optional] float value specifying the latitude for the
geographic layout
- nodeLong: [optional] float value specifying the longitude for the
geographic layout
### Edges list
One or more df with data on the edges. A typical edges list is expected to
be a file with at most three columns, giving the list of edges from a node
(first column) to other nodes (second column), possibly weighted by an
integer or floating number (third column). For instance:
1 2 0.5
1 3 1.4
...
18 124 0.1
### input df
Muxviz also uses a third data.frame that brings information on the list of
layers to be included in a multiplex, the corresponding labels and the
possible layout file to define node properties (e.g., ID, labels,
geographic coordinates, etc).
