spacemodR 0.3.0

New Features & Improvements

  • Soil interpolation (kriging): new functions to build soil contamination rasters from sampling points, without additional dependency: soil_variogram(), fit_soil_variogram(), soil_vgm(), krige_soil() (ordinary kriging or kriging with external drift), cv_soil() (random or spatial-block cross-validation), kernel_smooth_soil() (Gaussian smoothing reusing compute_kernel()), soil_grid() and source_covariates() (distance / wind covariates around a point source). New dataset soil_metaleurop (595 soil Cd, Pb, Zn samples) and new article “Soil contamination maps by kriging”.
  • EUNIS land cover: new function get_eunis_data() to download EUNIS Level 1 / Level 2 land cover rasters for a region of interest from the EEA Ecosystem Type Map v3.1 service, and new lookup dataset ref_eunis.
  • Trophic graph plots: plot() for trophic objects gains link weights and custom colors.
  • Dispersal: cleaned up the kernel dispersal code.

Packaging

  • Installable directly from GitHub with remotes::install_github("Qonfluens/spacemodR").
  • Source and binary packages are attached to each GitHub release.

spacemodR 0.2.0

Breaking Changes

  • Refactored trophic fluxes interface: The intake() function has been completely redesigned and renamed to flux() to better reflect the mathematical and ecological concept of transfer rates.
  • New pipe-friendly syntax: The definition of transfer parameters no longer uses multiple named arguments. Users must now initialize the table with flux() and chain specific rules using the new add_flux() function.
  • Namespace conflict resolution: The internal utility function previously named flux() (used within the transfer() function) has been renamed to avoid conflicts with the new main API.

New Features & Improvements

  • New add_flux() function: Allows for adding transfer rules in a readable, sequential manner (e.g., add_flux(from = "soil", to = "plant", value = ~ 10^x / 32)).
  • Global target rules: In add_flux(), if the source compartment (from) is not specified, the rule (value) is automatically applied to all links pointing to the target compartment (to).
  • Safe default values: The flux() function now features an explicit default parameter. It is highly recommended to use 1 (full transfer) or 0 (no transfer) instead of NA to prevent the propagation of missing values during subsequent model calculations.

spacemodR 0.1.3

CRAN release: 2026-02-20

  • Bug Fixes:
    • Fixed an rlang_error (replacement has length zero) in spacemodel raster layer sub-assignment within the Tutorial vignette.
    • Removed non-ASCII characters (smart quotes) from the DBFunc_BirdFuncDat dataset to pass CRAN checks.
    • Resolved R CMD Check notes regarding no visible binding for global variable (weight_global, weight_foraging, resistance).
  • Documentation & Data:
    • Added complete roxygen2 documentation for internal datasets: FmrBT, DBFunc_MamFuncDat, and DBFunc_BirdFuncDat.
    • Translated and enhanced the Food_Intake vignette into professional scientific English.
    • Updated the pkgdown website structure to use a clean 3-tier navigation system (Quick Start, Core Guides, Example Zoo).

spacemodR 0.1.2

  • New Features:
    • Added the Food_Intake module and dataset integration (FmrBT, EltonTraits) to compute Daily Food Intake (DFI).
    • Included the Eco-SSL (Ecological Soil Screening Levels) risk index assessment example.
  • Enhancements:
    • Improved the Omniscape_Connectivity tutorial with real-world spatial data for the Wood Mouse (Apodemus sylvaticus).

spacemodR 0.1.0

  • Initial Release:
    • Introduced the core spacemodel class for merging raster stacks and trophic networks.
    • Added transfer and dispersal modeling functions.
    • Integrated external Julia Omniscape connectivity algorithms.
