Earth map is usually presented flat. Geographical coordinates usually go from -180° to +180°. Spatial interpolations using coordinates may be tricky as -180° is equal to +180°. Here I propose a way to realize spatial interpolations on Earth as a sphere and then map the outputs in 3D using rgl. The …

SDMSelect: Cross-validation model selection and species distribution mapping
This library has originally been created for covariates selection to predict species distribution (biomass, density or presence/absence). Its final aim is thus to produce maps of predicted distributions (Look at vignette SDM_Selection). However, the core of the library is a N-times k-fold …
Mapping, spatial analyses and GIS with R
If you download the following presentation, you will find a presentation of different functions in the R-software useful for spatial data manipulations. Choosing the right libraries allows to create, import, modify, manipulate and map vector (shapefiles) or matrix (raster) spatial data. Your spatial …
