Functions to transform existing layers into new ones.
These functions merge multiple layers into one. The new layer is added to the network. If the input layers are no longer necessary, they must be explicitely erased.
flatten_ml
adds a new layer with the actors in the input layers and an edge between A and B if they are connected in any of the merged layers.
project_ml
adds a new layer with the actors in the first input layer and an edge between A and B if they are connected to the same actor in the second layer.
flatten_ml(n, new.layer = "flattening", layers = character(0), method = "weighted", force.directed = FALSE, all.actors = FALSE) project_ml(n, new.layer = "projection", layer1, layer2, method = "clique")
n |
A multilayer network. |
new.layer |
Name of the new layer. |
layers |
An array of layers belonging to the network. |
layer1 |
Name of a layer belonging to the network. |
layer2 |
Name of a layer belonging to the network. |
method |
This argument can take values "weighted" or "or" for |
force.directed |
The new layer is set as directed. If this is false, the new layer is set as directed if at least one of the merged layers is directed. |
all.actors |
If TRUE, then all the actors are included in the new layer, even if they are not present in any of the merged layers. |
