In mlr3spatiotempcv: Spatiotemporal Resampling Methods for 'mlr3'

mlr3spatiotempcv 2.2.0

Features

• Add "knndm" method from package {CAST} (#229)
• Add label_size to "spcv_block" to make label size configurable (#227)
• Add show_omitted for "spcv_buffer" method (#228)

mlr3spatiotempcv 2.1.0

• Add support for {blockCV} v3 and bump requirement to >= 3.1.2 (#222)
• Replace {raster} dependency in favor of {terra}
• Remove CLUTO algorithm and method due to CLUTO being non-downloadable anymore (#224)

mlr3spatiotempcv 2.0.3

• add label support for built-in tasks
• adhere to CRAN "noSuggests" policy

mlr3spatiotempcv 2.0.2

• Add error message when trying to create a TaskClassifST or TaskRegrST from an sf object
• Synchronize TaskClassifST or TaskRegrST with {mlr3spatial}
• Add support for mlr_reflections changes in {mlr3} > 0.13.4
• Adjust "Getting Started" vignette to recent API changes
• autoplot.ResamplingSptCVCstf(): Add missing support for argument axis_label_fontsize for x and y axes

mlr3spatiotempcv 2.0.1

Bugfixes

• autoplot.ResamplingSptCVCstf: when multiple folds are requested, the subplots are now returned again (before, the return was empty)
• autoplot.ResamplingSptCVCstf: the legend item for the "omitted" observations now displays the correct color and label again

mlr3spatiotempcv 2.0.0

Breaking

• Rename task cookfarm to cookfarm_mlr3. This was done to distinguish the cookfarm task implementation in {mlr3} better from the original cookfarm dataset. cookfarm_mlr3 also now comes with all rows of the upstream cookfarm task and not with a random subset as before.
• Rewrite mlr_resampling_spctcv_cstf implementation. The method will produce different fold results compared to {mlr3spatiotempcv} <= 1.0.1. This is because of a change/fix in the sampling behavior: before, an (unwanted) stratified sampling was done on time and space variables. While this matched the upstream implementation in {CAST}, this did not match with the actual theoretical underpinning described in the literature.
• {mlr3} API adaptations: TaskClassifST$new() and TaskRegrST$new() only accepts DataBackendDataTable. Support for sf objects has moved to as_task_*_st() which accepts sf objects directly and creates the DataBackend behind the scenes.

Features

• Add support for DataBackendRaster (@be-marc, #191).
• mlr_resampling_spctcv_cstf: a log message returns the column roles from the Task which are used for partitioning
• The help pages for all methods now describe the methods manually rather than importing the upstream documentation of the respective method.
• Task*ST classes now print column roles space and time (if set) (#198)
• autoplot() gains plot_time_var argument for 3D visualizations of mlr_resamplings_sptcv_cstf resamplings with only 'space' used for partitioning (#197)
• Vignette updates

Bugfixes

• All {mlr3spatiotempcv} methods now comply with the {mlr3} man file declaration logic.

Misc

• Escape all examples and tests for non-installed packages.
• The cookfarm_mlr3 task now sets column roles "space" and "time" for variables SOURCEID and Date, respectively.
• Harden CLUTO tests (#182)
• Large update for the "spatiotemporal" section in the mlr3book

mlr3spatiotempcv 1.0.1

• Fixed a issue which caused coordinates to appear in the feature set when a data.frame was supplied (#166, @be-marc)
• Add autoplot() support for "groups" column role in rsmp("cv")

mlr3spatiotempcv 1.0.0

Breaking

• autoplot(): removed argument crs. The CRS is now inferred from the supplied Task. Setting a different CRS than the task might lead to spurious issues and the initial idea of changing the CRS for plotting to have proper axes labeling does not apply (anymore) (#144)

Features

• Added autoplot() support for ResamplingCustomCV (#140)

Bug fixes

• "spcv_block": Assert error if folds > 2 when selection = "checkerboard" (#150)
• Fixed row duplication when creating TaskRegrST tasks from sf objects (#152)

Miscellaneous

• Upgrade tests to {vdiffr} 1.0.0
• Add {rgdal} to suggests and required it in "spcv_block" since it is required in {blockCV} >= 2.1.4 and {sf} >= 1.0

mlr3spatiotempcv 0.4.0

Features

• Support clustering coords only for "sptcv_cluto"
• Add as_task_* S3 generics: as_task_classif_st.data.frame(), as_task_classif_st.DataBackend(), as_task_classif_st.sf(), as_task_regr_st.data.frame(), as_task_regr_st.DataBackend(), as_task_regr_st.sf(), as_task_classif.TaskClassifST(), as_task_regr.TaskRegrST() (#99)
• Add "spcv_tiles" and "repeated_spcv_tiles" (#121)
• Add "spcv_disc" (#115)

Bug Fixes

• Fixed train set issues for sptcv_cstf() with space and time var (#135)
• Fixed $folds() active binding returning wrong fold number (#120)
• Add missing man IDs (#122)

Misc

• Add example 2D spatial plots to spatiotemp-viz vignette
• Add {caret} to Suggests
• "Cstf" methods: remove arguments in favor of param set to align with other methods (#122)
• Inherit documentation from upstream functions (#117)
• Vignette: Update and categorize table listing all implemented methods

mlr3spatiotempcv 0.3.0

New Features

• autoplot.ResamplingSptCVCstf(): add 2D plotting method (#106)
• autoplot.ResamplingSptCVCstf(): add arguments show_omitted and static_image (#100)
• autoplot() (all methods): allow adjusting point size via ... (#98)

Maintenance

• Remove {GSIF} package due to CRAN archival and host the cookfarm dataset standalone
• Use Cstf method for spatiotemporal viz vignette
• Fix help page content of ResamplingRepeatedSptCVCstf (beforehand the Cluto method was referenced accidentally)
• Fix segfault in autoplot.ResamplingSpcvBlock example when rendering pkgdown site (unclear why this happens when show_labels = TRUE)
• Update autoplot() examples and related documentation
• Remove duplicate resources in Tasks "see also" fields
• Skip a test on Solaris and macOS 3.6
• Optimize "Spatiotemporal Visualization" vignette

mlr3spatiotempcv 0.2.1

• Add support for rasterLayer argument in blockCV::spatialBlock() (#94)
• Ensure that blockCV::spatialBlock() functions actually returns the same result when invoked via {mlr3spatiotempcv} (#93). Among other issues, blockCV::spatialBlock(selection = "checkerboard") was ignored.
• Get coordinates names from {sf} objects dynamically. Before some functions would have errored if the coordinate names were not named "x" and "y".

mlr3spatiotempcv 0.2.0

• Add support for {sf} objects for Task*ST creation (#90)
• "Getting Started" vignette: add example how to create a spatial task

mlr3spatiotempcv 0.1.1

• CRAN-related changes
• Support ordered factors in TaskClassifST creation (#84)

mlr3spatiotempcv 0.1.0

• Initial CRAN release
