Changes in version 2.0.0.9000                      

Updates to rely on terra and sf for long-term package stability

  - isotopeAssignmentModel now relies on terra instead of raster.
    Depreciated the parallel processing capability within this function
  - schoenersD now expects inputs of SpatRasters, will automatically
    convert raster-class objects.
  - New function schoenersDsimmatrix generates a similarity matrix
    comprising Schoener's D values for all layers in a SpatRaster.
    Function simmatrixMaker retained as a legacy/depreciated function
    that still uses rasterStacks as input.

TODO -- make schoenersDsimmatrix that runs in parallel

                 Changes in version 0.3.0 (2024-02-15)                  

New function

  - New function makeMultiMonthIsoscape to combine multiple monthly
    isoscapes and error maps into one of each, for making month-specific
    isoscape assignments.

Tweaks

  - schoenersD function now automatically normalizes surfaces to sum
    to 1, rather than just advising it in the documentation.
  - corrected documentation parameter names in .assignmentMaker

                 Changes in version 0.2.6 (2020-07-03)                  

Publication update

  - Publication introducing some of isocat's functionalities is out.
  - Package citation is created, update. See citation("isocat").
  - Updated package description with links, typo fixes.

Vignette improvements

  - Added some additional text on transfer functions

                 Changes in version 0.2.5 (2020-03-28)                  

Rewrote function isotopeAssignmentModel

  - Function now checks for identical projections and resamples
    secondary models automatically.
  - Multiple secondary models can be incorporated as a rasterStack.
  - Replaced parallelization package with parallel::mcmapply.
  - Removes bug where secondary models not created when running in
    parallel.

Minor tweaks

  - Remove now-unnecessary import of package dplyr.
  - Resolved bug in vignette example by adding 'stringsAsFactors =
    FALSE' to example dataframe.
  - Removed defunct class test for individual IDs from
    meanAggregateClusterProbability function.

isocat 0.2.4

Optimize 'cumsumbelow' function

  - Function deals with NA values more efficiently.
  - When imported into makeCumSumSurface, function iterates faster over
    RasterLayers.
  - Removed dependency on purrr::map and pipe operators within function.
  - The purrr package removed from suggested packages.

Bug fix for R 4.0.0

  - Modified conditional class check within cumsumAtSamplingLocation and
    clusterSimmatrix functions, in anticipation of change to matrix
    objects inheriting from class "array" (which broke old class check
    code).

Vignette updated

  - Vignette updated, examples improved, enable stage-skipping with
    working examples.

Minor tweaks

  - Tweaked package title.
  - Added 'additionalModel_name' argument to isotopeAssignmentModel.
  - Added 'seealso' and 'alias' components to function documentation.
  - Fixed typo in examples for makeQuantileSimulationSurface function.
  - Clarified function description for schoenersD function.
  - Tweaked wording in example for cumsumAtSamplingLocation function.

                 Changes in version 0.2.3 (2019-06-07)                  

Bug fixes

  - Updated data file to realistic isoscape standard deviations.
  - Fixed dependency / import issues throughout.
  - Adjusted file names for cross-platform compatibility.
  - Replaced references to superseded snow package with calls to
    parallel.

Vignette updated

  - Vignette updated, TODO's resolved.

Minor Tweaks

  - Expanded DESCRIPTION metadata.
  - Resolved spelling errors and improved style throughout package.
  - Fixed broken/suspect email and IsoMAP links.
  - Corrected donttest wrappers on long analyses.
  - Added examples to several functions.
  - Switched from 'installed.packages' to '!requireNamespace' to check
    for package loading.

                        Changes in version 0.2.2                        

Vignette Included

  - Added vignette with descriptions and example applications of all
    functions.

New Functions

  - New suite of functions for working with cumulative sums:
    cumsumbelow, makeCumSumSurface, cumsumAtSamplingLocation.
  - Added a meanAggregateClusterProbability function to create mean
    probability-of-origin map based on cluster assignments (for
    individuals of similar origin).
  - Added projectSummarySurface function to show which RasterLayer in a
    stack has highest value at any given location.

Bug fixes

  - Fixed minor issue with running makeQuantileSimulationSurface on
    object of class RasterLayer.
  - Updated clusterSimmatrix function to match pvclust version 2.0-1
    with debug of r parameter.
  - Replaced buggy projectCluster function with alternative function
    (projectSummarySurface; see isocat vignette).

                        Changes in version 0.2.1                        

New Functions

  - Added a schoenersD function that compares the spatial similarity of
    two surfaces.
  - Added a makeQuantileSimulationSurface function that converts a
    surface to a quantile-simulation surface.

Minor Tweaks

  - Improved code readability within several functions.

                        Changes in version 0.2.0                        

  - Added a NEWS.md file to track changes to the package.
  - Renamed package from IsoModAT (Isotope Models of Animal Origin
    Analytical Toolset) to isocat (Isotope Clustering and Assignment
    Tools).
  - Specified CC0 license.

New Functions

  - Added a makeQuantileSurface function to converts normalized
    probability surfaces to quantile surface. Matches makeOddsSurface.
  - Added a oddsAtSamplingLocation function that finds odds ratios of
    origin probability at a set of coordinates within a normalized
    probability surface. Matches quantileAtSamplingLocation.
