I am looking for a R code for Gaussian Mixture Models to infer group membership using a clustering of spatio-temporal data stream such as used by Psorakis et al. 2012 originally written in Matlab: Psorakis, I., Roberts, S. J., Rezek, I., & Sheldon, B. C. (2012). Inferring social network structure in ecological systems from spatio-temporal data streams.
