## Function to combine networks from a list of igraph objects

### Description

`xCombineNet` is supposed to combine networks from a list of igraph objects.

### Usage

    xCombineNet(list_ig, combineBy = c("union", "intersect"),
    attrBy = c("intersect", "union"), keep.all.vertices = FALSE,
    verbose = TRUE)

### Arguments

`list_ig` | a list of "igraph" objects or a "igraph" object
`combineBy` | how to resolve edges from a list of "igraph" objects. It can be "intersect" for intersecting edges and "union" for unionising edges (by default)
`attrBy` | the method used to extract node attributes. It can be "intersect" for intersecting node attributes (by default) and "union" for unionising node attributes
`keep.all.vertices` | logical to indicate whether all nodes are kept when intersecting edges. By default, it sets to false
`verbose` | logical to indicate whether the messages will be displayed in the screen. By default, it sets to true for display

### Value

an object of class "igraph"

none
