CRAN Version

Major changes:

• sf and sp objects are allowed as input and output (use returnclass = "sf" for sf output).
• functions use sf for spatial computation.
• rasterToContourPoly() (based on rgeos & sp) is deprecated in favor of isopoly() (based on isoband and sf).
• bug fix in smoothy for some computations with NAs.
• addition of a dataset hospital, with hospital points and capacity and Paris polygon.
• suppression of the QGIS vignette, irrelevant in regard to QGIS v3, and not really specific to SpatialPosition

CRAN Version

Major changes:

• Introduce mcStewart to compute stewart potentiels using parallel processing
• Introduce smoothy to compute distance weighted mean.
• Introduce a vignette on how to SpatialPosition with QGIS.

Minor changes:

• (Re)introduce a longlat param in stewart, mcStewart, huff and reilly to select between eucliean and great circles distances.
• Add a bypassctrl param in stewart, huff and reilly to allow computations on large datasets
• More points in the default mask of raster poly
• Rewrite of CreateGrid and rasterToContourPoly functions

CRAN Version

Minor changes:

• Check mask size and validity in ratserToContourPoly
• Better SpatialPolygonsDataFrame output in rasterToContourPoly
• Default distance computation is in meters using the Great Circle distance (WGS84 ellipsoid) method.

CRAN Version

Major changes:

• Introduce the quickStewart function that outputs stewart contour polygons easily. Ratio of potentials are allowed.
• Introduce rasterToContourPoly to replace contourStewart.
• contourStewart is now deprecated. Use rasterToContour from raster to output contour lines and rasterToContourPoly from SpatialPosition to output polygons.

Minor changes:

• A resolution is set by default in CreateGrid.
• Vignettes are updated to reflect major changes.

CRAN Version

Major changes:

• Better code for contourStewart.
• Better legend for plotStewart
• New vignette 'Stewart Potentials: a Use Case'.

Minor changes:

• Minor changes in documentation and vignette.
• Add 'cartography' in suggested packages.
