xConverter: Function to convert an object between graph classes

Description

xConverter is supposed to convert an object between classes "igraph", "dgCMatrix", "dtree", "lol", and "json".

Usage

xConverter(obj, from = c("igraph", "dgCMatrix", "dtree", "lol",
"json"),
to = c("dgCMatrix", "igraph", "dtree", "lol", "json", "igraph_tree"),
verbose = TRUE)

Arguments

obj

an object of class "igraph", "dgCMatrix", "dtree", "lol", and "json"

from

a character specifying the class converted from. It can be one of "igraph", "dgCMatrix", "dtree", "lol", "json"

to

a character specifying the class converted to. It can be one of "igraph", "dgCMatrix", "dtree", "lol", "json" and "igraph_tree"

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", "dgCMatrix", "dtree", "lol", or "json".

Examples

# NOT RUN {
# generate a ring graph
g <- make_ring(10, directed=TRUE)

# convert the object from 'igraph' to 'dgCMatrix' class
xConverter(g, from='igraph', to='dgCMatrix')

# }
# NOT RUN {
# Conversion between 'dgCMatrix' and 'igraph'
# ig.EF (an object of class "igraph" storing as a directed graph)
g <- xRDataLoader('ig.EF')
g

# convert the object from 'igraph' to 'dgCMatrix' class
s <- xConverter(g, from='igraph', to='dgCMatrix')
s[1:10,1:10]

# convert the object from 'dgCMatrix' to 'igraph' class
ig <- xConverter(s, from="dgCMatrix", to="igraph")
