Graph: Graph

In shazhe/mvst0: Multi-variate ST modelling on globe

Description

A graph is a collection of links (collected using link_list) and blocks (collected using block_list).

Usage

Graph(e = new("link_list"), v = new("block_list"))

Arguments

e	an object of class link_list containing all the edges in the graph.
v	an object of class block_list containing all the blocks in the graph.

Value

Object of class Graph

Examples

## Not run: 
require(Matrix)
data(icesat)
data(surf_fe)

## First create observation object
icesat_obs <- Obs(df=icesat,
                 abs_lim = 5,
                 avr_method = "median",
                 box_size=100,
                 name="icesat")

## Now create GMRF defined over some FE basis
Mesh <- initFEbasis(p=surf_fe$p,
                    t=surf_fe$t,
                    M=surf_fe$M,
                    K=surf_fe$K)

mu <- matrix(0,nrow(Mesh),1)
Q <- sparseMatrix(i=1:nrow(surf_fe$p), j = 1:nrow(surf_fe$p), x = 1)

my_GMRF <- GMRF(mu = mu, Q = Q,name="SURF",t_axis = 0:6)
SURF <-GMRF_basis(G = my_GMRF, Basis = Mesh)

L1 <- link(SURF,icesat_obs)
e <- link_list(list(L1))
v <- block_list(list(O = icesat_obs, G = SURF))
G <- new("Graph",e=e,v=v)
