                Introduction to the ICON R package, allowing access to 1,075 complex networks.
              
          
    Setup

To prepare for the vignette, we load the necessary R packages and
associated datasets.
# load R packages (both on CRAN)
library(ICON)
library(network)   # for network analysis

library(ggplot2) # for network visualization

                A short tutorial on conducting topological data analysis in R.
              
          
    Topological data analysis (TDA) in R

Purpose

Topological data analysis (or TDA) is a growing discipline with great potential.
Unfortunately, the difficulty of learning the software used to perform TDA on real datasets is a nontrivial task adds an oft intimidating barrier to entry.
This Gist provides a straightforward tutorial to using the TDAstats package to conduct topological data analysis (specifically, persistent homology using Vietoris-Rips simplicial complexes) in R.
N.B. this Gist largely assumes the reader is familiar with a Vietoris-Rips simplicial complex, persistent homology, topological barcodes, and persistence diagrams.
Please make sure you have at least a basic understanding of these terms prior to proceeding.
