Walking in Facebook: A Case Study of Unbiased Sampling of OSNs
TLDR
The goal in this paper is to obtain a representative (unbiased) sample of Facebook users by crawling its social graph using several candidate techniques, and introduces online formal convergence diagnostics to assess sample quality during the data collection process.

ergm: A Package to Fit, Simulate and Diagnose Exponential-Family Models for Networks.
TLDR
Ergm has the capability of approximating a maximum likelihood estimator for an ERGM given a network data set; simulating new network data sets from a fitted ERGM using Markov chain Monte Carlo; and assessing how well a fittedERGM does at capturing characteristics of a particular networkData set.

network: A Package for Managing Relational Data in R
TLDR
The network package provides an class which may be used for encoding complex relational structures composed a vertex set together with any combination of undirected/directed, valued/unvalued, dyadic/hyper, and single/multiple edges; storage requirements are on the order of the number of edges involved.

Practical Recommendations on Crawling Online Social Networks
TLDR
This paper develops a practical framework for obtaining a uniform sample of users in an online social network by crawling its social graph by considering and comparing several candidate crawling techniques and introduces online formal convergence diagnostics to assess sample quality during the data collection process.
