LandR 1.1.0

  • move LandWeb-specific functions to LandWebUtils package (#86)
  • Colors -- new function to help with terra migration.
  • prepInputsFireYear can now handle rasterToMatch that is a SpatRaster
  • drop support for R < 4.2 due to change in dependency package MuMIn (Sept 2022)
  • new functions to download a set of default biogeoclimatic variables used across several modules, and subset data layers from different time periods according to a year. These functions may only be here temporarily.
  • new raster/terra utility and plotting functions
  • new functions related to producing default permafrost input data for modules. These functions may only be here temporarily.

LandR 1.0.9

  • new function: nonForestedPixels used to detect pixels without species cover or a non-forested land-cover class;
  • new function: prepRawBiomassMap used to create rawBiomassMap;
  • new function: prepRasterToMatch used to create RasterToMatch and RasterToMatchLarge;

LandR 1.0.8

  • drop support for R 3.6
  • prepInputsStandAgeMapcan now accept firePerimeters layer, avoiding inner download if layer is present;
  • new assertion (assertSppVectors) to check that species match between vectors (e.g. tables, colours and species list vector);
  • new function sppHarmonize that deals with the 3 potential ways for a user to input the sim$sppEquiv, P(sim)$sppEquivCol, and sim$sppNameVector;
  • update Eliot's email address;
  • new functions: speciesInStudyArea and `species;
  • remove undeclared dependency package Require;
  • age imputation in makeAndCleanInitialCohortData can now be turned off;
  • fix bug in LANDISDisp(): skip dispersal when src or rcv data.tables are empty;
  • initial cohort biomass (calculated in .initiateNewCohorts) can now be a fixed integer or, as before, calculated using the LANDIS-II Biomass Succession Extension v3.2.1 approach (Scheller & Miranda 2015);
  • fix bug in prepInputsFireYear();
  • drop single-level factor terms in statsModel;

LandR 1.0.7

  • Several changes to accommodate the tracking and optional removal of pixels; data suffered data imputation in Biomass_borealDataPrep;
  • assertColumns gives better message for which columns are incorrect/missing;
  • minRelativeBDefaults is now a function so they are more easily accessible ;
  • statsModel was pulling along with it all the data, 5x. Now it does not. The Caching of this should be fast and small now.

LandR 1.0.5

  • Support for refitting modelBiomass (see Biomass_boreaDataPrep) with scaled data or different optimizer;
  • Changes to loadkNNSpeciesLayers and prepSpeciesLayers_KNN prevent issues when default URL is down, or working offline (but layers are present locally);
  • Several changes to accommodate LCC 2010 dataset;
  • New columns to sppEquivalenciesCA (PSP, BC_Forestry and FuelClass);
  • Lowered values of dummy rawBiomassMap;
  • passing fireURL = NULL to prepStandAgeMap() bypasses age imputation;

LandR 1.0.4

  • New assertion for validation data;
  • New function sppEquivCheck;
  • loadKNNSpeciesLayers can accept a sppEquiv table with one column
  • Improved documentation for speciesEquivalencies_CA data;

LandR 1.0.3

  • new function to calculate fire severity as biomass loss;
  • bug fixes and improvements to to speciesTableUpdate;

LandR 1.0.2

  • Fixes and further speed improvements to seed dispersal functions and general code cleaning;

LandR 1.0.1

  • Complete rewrite of LANDISDisp now (back to) native R. It is about 15x faster than the Rcpp implementation, and much simpler, with about 30% of the number of lines of code. It was inspired by the "spiral" approach as was used in the Rcpp in the pre-1.0.0 version of LandR, but much more efficiently as it is now correctly identifies every pixel outward from a centre pixel using raster::focalWeight, with the maximum of the seeddispersal_max across all species. RAM use appears under control, even for large problems (tested on 50M pixel Raster with 8M potential Source pixels and 500,000 Receiving pixels, with a peak additional RAM of 3 GB during LANDISDisp); LANDISDisp now accommodates sub-cellSize dispersal distances, using the original Ward Dispersal equation. Previously, the sub-pixel dispersal was treated as if it was starting from the centre of the pixel. So, if less than a full pixel, then very little horizontal transfer. This has the effect that there will be a large increase in horizontal transfer for the species that have small seeddistance_max (i.e., less than cell size);
  • add new function prepSpeciesLayers_ONFRI;

Bugfixes

  • LANDISDisp did not correctly handle speciesCode when it is a factor. This is a common possibility. It now handles these correctly.

LandR 0.0.5

  • new function updateSpeciesTable (moved from LandWebUtils) to allow user to update species parameters by passing a named list.

LandR 0.0.4

  • assignLightProb now allows interpolating germination probability between species shade tolerance levels for any given stand shade value. This allows for for decimal values in species shade tolerance traits and greater fine tuning of shade-related germination probabilities.

LandR 0.0.3

  • rounding of age classes and biomass now occurs only inside makeCohortDataFiles, as it is the last thing to do before making cohortData
  • rounding of age and biomass has been taken out of 3 other functions -- .createCohortData, makeAndCleanInitialCohortData , and a hard coded bit in Biomass_borealDataPrep
  • updated source for kNN databases (now using v1, instead of v0) - this involved changes in the URLs and how the data is downloaded;
  • statsModel function has a new argument to improve caching with reproducible::Cache (i.e. not used internally);
  • function arguments that where previously called time, are now called currentTime - these changes are matched in LandR Biomass modules
  • minor code clean-ups/bugfixes and improved clarity

LandR 0.0.2

  • Bug fixes in imports (DESCRIPTION)
  • new function overlayLCCs which will help with overlaying more than one land cover classification raster.
  • major revisions to convertUnwantedLCC to accommodate more cases and eliminate redundant arguments.
  • prepInputsLCC() now works with "LCC10"
