SocialMediaLab is an R package that provides a suite of tools for collecting and constructing networks from social media data. It provides easy-to-use functions for collecting data across popular platforms (Instagram, Facebook, Twitter, and YouTube) and generating different types of networks for analysis. SocialMediaLab also collects the associated text data from social media platforms (e.g. Tweets, Facebook fan page posts and comments, YouTube video comments). SocialMediaLab was created by Timothy Graham from the University of Queensland (who is also the maintainer of the package) and Robert Ackland from the Australian National University. The latest 'official' version of the package can be found here: https://cran.r-project.org/web/packages/SocialMediaLab/index.html The development version, support and further information can be found here: https://github.com/voson-lab/SocialMediaLab Also, see the SocialMediaLab page on the VOSON Lab website: http://voson.anu.edu.au/SocialMediaLab - this has several "how to" guides, including an "Absolute Beginners Guide to SocialMediaLab" tutorial aimed at people with little or no programming experience. The following 5-day course (Canberra, 18-22 January 2016) will have a strong focus on SocialMediaLab: https://www.acspri.org.au/summerprogram2016/big-data-analysis-social-scienti... We are also available for in-house/customised training sessions! SocialMediaLab would not be possible without key packages by other authors in the R community, particularly: igraph, Rfacebook, instaR, twitteR, data.table, tm, and httr. Please feel free to send us suggestions and report bugs (via github page), and we welcome contributions to SocialMediaLab! -- Dr Robert Ackland Associate Professor, School of Sociology and Centre for Social Research and Methods Leader, Virtual Observatory for the Study of Online Networks (VOSON) Lab <http://voson.anu.edu.au> Australian National University
