 misc 

Set of tools for reading, writing and transforming spatial and seasonal data, model selection and specific statistical tests for ecologists. It includes functions to interpolate regular positions of points between landmarks, to discretize polylines into regular point positions, link distant observations to points, read subsets of big rasters, compute zonal statistics or table of categories from raster  within polygons or circular buffers. The package also provides miscellaneous functions for model selection, spatial statistics and inference on diversity indexes, geometries, writing data.frame with Chinese characters, and some other functions for field ecologists.
