“…Moreover, the R programming language (R Core Team 2017) has various packages devoted to geostatistics, such as the gstat package for geostatistical modeling, prediction and simulation (Pebesma and Wesseling 1998;Pebesma 2004;Pebesma and Bivand 2005), geoR (Ribeiro Jr. and Diggle 2001;Diggle and Ribeiro Jr. 2007), which contains functions for model-based geostatistics, as well as the geospt (Melo, Santacruz, and Melo 2015), RandomFields (Schlather, Malinowski, Menck, Oesting, and Strokorb 2015) and RGeostats (Renard, Desassis, Beucher, Ors, and Laporte 2014) packages, or ad-hoc routines for graphical interface in the ecological modeling software Bio7 (Austenfeld and Beyschlag 2012) or for exploratory spatial data analysis (Laurent, Ruiz-Gazen, and Thomas-Agnan 2012). Other contributions concern specialized routines and packages for spatio-temporal analysis (De Cesare, Myers, and Posa 2002;De Iaco, Myers, Palma, and Posa 2010;Pebesma 2012;Gabriel, Rowlingson, and Diggle 2013).…”
