Spatial Designs for Ecological and Environmental Surveys R package MBHdesign version 2.3.15 CRAN Task View: ExperimentalDesign (https://CRAN.R-project.org/view=ExperimentalDesign) CRAN Task View: OfficialStatistics (https://CRAN.R-project.org/view=OfficialStatistics) CRAN Task View: Spatial (https://CRAN.R-project.org/view=Spatial) Provides spatially survey balanced designs using the quasi-random number method described Robinson et al. (2013) <doi:10.1111/biom.12059> and adjusted in Robinson et al. (2017) <doi:10.1016/j.spl.2017.05.004>. Designs using MBHdesign can: 1) accommodate, without substantial detrimental effects on spatial balance, legacy sites (Foster et al., 2017 <doi:10.1111/2041-210X.12782>); 2) be based on points or transects (foster et al. 2020 <doi:10.1111/2041-210X.13321> and produce clustered samples (Foster et al. (in press). Additional information about the package use itself is given in Foster (2021) <doi:10.1111/2041-210X.13535>.
