CAST 1.0.0

  • new features:
    • calculate local point density within AOA

    • geodist allows calculating temporal distances
    • ffs now can be run in parallel (Linux only)
    • vignette "Cross-validation methods in CAST"
    • knndm in feature space (experimental)
    • nndm in feature space (experimental)
  • modifications:
    • function DItoErrormetric renamed to errorProfiles and allows for other dissimilarity measures
    • Improvement and homogenization of plotting methods for nndm, knndm and geodist objects
    • aoa and trainDI weight now allows list input
    • vignette on Introduction to CAST updated

CAST 0.9.0

  • new features:
    • CAST functions now return classes with generic plotting and printing
    • new dataset for examples, tutorials and testing: data(splotdata)
  • modifications:
    • calibrate_aoa is now DItoErrormetric and returns a model (see function documentation)
    • plot_geodist is now geodist. The result can be visualized with plot()
    • plot_ffs is now plot(ffs)
  • bug fix:
    • fix issue #65 (threshold)

    • failed checks on Fedora 34 fixed

CAST 0.8.0

  • new features:
    • knndm as an alternative to nndm for large training data
  • modifications:
    • transition from raster to terra

CAST 0.7.1

  • new features:
    • Mahalanobis distance for AOA assessment as option
  • modifications:
    • faster estimation of the AOA
    • parallel option for AOA deprecated (see vignette)
      • delineation of the default threshold fixed as suggested in github.com//issues/46
  • bugfix:

CAST 0.7.0

  • new feature:
    • nndm cross-validation as suggested by Milà et al. (2022)
  • modifications
    • plot_geodist works with NNDM
    • trainDI works with NNDM
    • rename of parameter folds in AOA and trainDI

CAST 0.6.0

  • new feature:
    • trainDI allows to calculate the DI of the training dataset separately from the aoa function
    • plot and print functions for the AOA
    • function to plot nearest neighbor distance distributions in geographic and feature space
    • function global_validation added
  • modifications
    • extensive restructuring of the AOA function
    • ffs and bss can be used with global_validation
  • bugfix:
    • error in manual assignment of weights fixed

CAST 0.5.1

  • resolved dependence on package "GSIF" which was removed from the CRAN repository

CAST 0.5.0

  • new feature:
    • AOA can run in parallel
    • calibration of the DI (calibrate_aoa)
  • bugfix:
    • aoa will work now with large training sets
  • modifications:
    • default threshold of AOA changed

CAST 0.4.2

  • new feature:
    • aoa now working with categorical variables
  • bugfix:
    • fixed error in ffs when >170 variables are used
  • minor changes:
    • changed order of parameters in aoa
    • tutorial "Introduction to CAST" improved

CAST 0.4.1

  • new feature:
    • vignette: tutorial introducing the "area of applicability"
    • variable threshold for aoa
    • various modifications in aoa in line with submitted paper

CAST 0.4.0

  • new feature:
    • new function "aoa": quantify and visualize the area of applicability of spatial prediction models
    • "minVar" in ffs: Instead of always starting with 2-pair combinations, ffs can now also be started with combinations of more variables (e.g starting with all combinations of 3)
  • bugfix:
    • ffs failed for "svmLinear" in previous version because of S4 class issues. Fixed now.

CAST 0.3.1

  • bugfix:
    • CreateSpaceTimeFolds accepts tibbles
    • CreateSpaceTimeFolds automatically reduces k if necessary
    • ffs accepts further arguments taken by caret::train
  • new feature: plot_ffs has option to plot selected variables only

CAST 0.3.0

  • new feature: Best subset selection (bss) with target-oriented validation as (very slow but very reliable) alternative to ffs

  • minor adaptations: verbose option included, improved examples for ffs

  • bugfix: minor adaptations done for usage with plsr

CAST 0.2.1

  • new feature: Introduction to CAST is included as a vignette.

  • bugfix: minor error fixed in using user defined metrics for model selection.

CAST 0.2.0

  • bugfix: ffs with option withinSE=TRUE did not choose a model as "best model" if it was within the SE of a model that was trained in an earlier run but had the same number of variables. This bug is fixed and if withinSE=TRUE ffs now only compares the performance to models that use less variables (e.g. if a model using 5 variables is better than a model using 4 variables but still in the SE of the 4-variable model, then the 4-variable model is rated as the better model).

  • new feature: plot_ffs plots the results of ffs to visualize how the performance changes according to model run and the number of variables being used.

CAST 0.1.0

Initial public version on CRAN
