graph_coerce_list: Coercion of graphs represented as lists

In gRbase: A Package for Graphical Modelling in R

Coercion of graphs represented as lists

Description

Coercion of graphs represented as lists to various graph formats.

Usage

g_ugl2ig_(zz, vn = NULL)

g_ugl2dm_(zz, vn = NULL)

g_ugl2sm_(zz, vn = NULL)

g_ugl2XX_(zz, outtype, vn = NULL)

g_dagl2ig_(zz, vn = NULL)

g_dagl2dm_(zz, vn = NULL)

g_dagl2sm_(zz, vn = NULL)

g_dagl2XX_(zz, outtype, vn = NULL)

g_adl2ig_(zz)

g_adl2dm_(zz)

g_adl2sm_(zz)

g_adl2XX_(zz, outtype)

g_M2adl_(amat)

g_M2ugl_(amat)

g_M2dagl_(amat)

g_ugl2M_(glist, vn = NULL, result = "matrix")

g_dagl2M_(glist, vn = NULL, result = "matrix")

g_adl2M_(alist, result = "matrix")

Arguments

zz	An object representing a graph.
vn	The names of the vertices in the graphs. These will be the row and column names of the matrix.
outtype	What should a list be coerced to.
amat	Adjacency matrix (dense or sparse dgCMatrix).
glist	A list of generators where a generator is a character vector. If interpreted as generators of an undirected graph, a generator is a complete set of vertices in the graph. If interpreted as generators of a dag, a generator (v1,...,vn) means that there will be arrows from v2,...,vn to v1.
result	A graph object.
alist	An adjacency list.

Examples

## Sparse and dense adjacency matrices converted to adjacency list 
g1 <- ug(~a:b + b:c + c:d, result="matrix")
g2 <- ug(~a:b + b:c + c:d, result="dgCMatrix")
g_M2adl_( g1 )

## Sparse and dense adjacency matrices converted to cliques
g_M2ugl_( g1 )

## Sparse and dense adjacency matrices converted to cliques
g_M2dagl_( g1 )

## g_M2adl_( g2 ) ## FIXME FAILS for sparse matrix
## g_M2ugl_( g2 ) ## FIXME Is there an issue here??
## g_M2dagList( g2 ) ## Fails for sparse matrix
