isocat 0.2.3

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• Replaced references to superseded snow package with calls to parallel.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.

isocat 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).

isocat 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.

isocat 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.
