Graphi

Description

Simple script written in R to create adjacency matrix and print it as a graph. It uses the argparse library to get command line arguments.

Usage

You can create the matrix and use it to generate a graph. You can do operation to change the matrix information directly from your console. The graph will be printed in a pdf file.

To see the commands type ./graphi.R --help:

usage: ./graphi.R [-h] [-c] [-vm] [-ed] [-pg] [-i IMPORT] [-sn SEARCH_NODE]
                  [-sb SET_BOW] [-rb REMOVE_BOW] [-rn REMOVE_NODE]
                  [-an ADD_NODE] [-nv NODE_VALUE] [-cv CHANGE_VALUE]
                  [-nc NODE_CONNECTION] [-bv BOW_VALUE]

Library

You need these libraries:

• library("igraph") - to create graph from the adjacency matrix
• library("argparse") - to parse command line arguments
• library("cgwtools") - to save the environment
