gridgraph

Create or instantiate an graph class graph from the faces of an icosahedral grid

Description

The function can be applied to both grids and to facelayer-class object of logical values. The resulting graph will have the characteristics of the original grid (directed/undirected etc.).

Usage

gridgraph(x, ...)

## S4 method for signature 'trigrid'
gridgraph(x, directed = FALSE, distances = FALSE)

## S4 method for signature 'hexagrid'
gridgraph(x, directed = FALSE, distances = FALSE)

## S4 method for signature 'facelayer'
gridgraph(x)

Arguments

`x`	(`trigrid`, `hexagrid` or `facelayer`) The icosahedral grid or `facelayer`.
`...`	Arguments passed to the class specific methods.
`directed`	`logical` Defaults to `FALSE`, creating an undirected graph. If `TRUE`, then the graph will be directed.
`distances`	`logical` Defaults to `FALSE`. If `TRUE`, then the distances between the linked faces will be calculated and will be rendered to the edges as `"dist"`.

Value

The function returns an undirected igraph graph.
