# fasterRaster 8.4.0.5 (2025-02-25)
o Added vignette "3-dimensional objects".  
o `[` is faster.  
o `%in%` and `match()` work when `faster(useDataTable = FALSE)` and `table` argument is a character.  
o `extract()` is faster.  
o `fast()` has better error catching for vectors.  
o `spatSample()` is faster when `values` or `cats` is `TRUE`.  
o Hopefully fixed some issues when linking to `rgrass` and `terra` documentation noted by R Bivand and R Hijmans.  

# fasterRaster 8.4.0.3 (2024-12-15)

### Bug and issue fixes
o Many minor fixes for CRAN submission!  
o Comparison between a string and a categorical `GRaster` using logical operators like `<` or `==` returns a categorical raster.  
o `as.factor()` is now properly exported.  
o `centroids()` has the option to exit gracefully if the `addons` check fails.  
o `crds()` now works for `GVector`s that lacked an internal **GRASS** database. Hidden function `.crds()` accepts a `cats` argument, making it potentially faster.   
o `fast()` correctly defines region on import of raster.  
o `mow()` example works.  
o `spatSample()` works when sampling by `stratum`.  
o `.rbind()` is a hidden function which accepts a `cats` argument that concatenates vectors faster than `rbind()`.   
o Issues with some examples were fixed.  

# fasterRaster 8.4.0.2 (2024-12-09)
o Fixed issues from CRAN R CMD precheck.  

# fasterRaster 8.4.0.0 (2024-11-20)

### Potentially code-breaking changes
o By default, **fasterRaster** now uses `data.frames`, not `data.table`s from the `data.table` package (see `?faster`).  
o Removed option `clean` from `faster()`. Files are now removed from the **GRASS** cache as needed.  
o `mow()` can delete a single `GRaster` or `GVector`, a list of rasters and/or vectors, or all objects in a particular environment.  

### Enhanced functionality and new functions
o `centroids()` locates the center of `GVector`s.  
o `coordRef()` returns information about an object's coordinate reference system.  
o `project()` is now much faster when projecting a `GRaster` using the `terra` or `fallback` values for `res`.  
o `spatSample()` is faster.  
o Support for **GRASS** addons and methods based on them!!!  

### Bug and issue fixes
o `GVector[i]` does not fail when all geometries are selected.  
o Comparison with categorical `GRaster`s (e.g., `<`, `==`, etc.) does not fail when `faster('useDataTable')` is `FALSE`.

o `levels()` does not fail when `faster('useDataTable')` is `FALSE`.  
o `segregate()` works when setting `useDataTable` is `FALSE`.  
o `subset()` no longer fails.  
o `subst()` does not fail when `faster('useDataTable')` is `FALSE`.  

# fasterRaster 8.4.0.7028 (2024-10-24)

### Enhanced functionality and new functions
o `grassHelp()` can show the **GRASS** manual "table of contents" (argument `"toc"`).  
o `longlat()` can now return rasters with cell values equal to their coordinates in map units (previously, only coordinates in degrees were returned).  
o For functions that are complicated or have extended references, added a note to the `@seealso` tag to see the respective **GRASS** manual page using `grassHelp()`.  

### Bug and issue fixes
o `project()` correctly restores the user's "location" to that of the newly projected `GRaster`.  

# fasterRaster 8.4.0.7027 (2024-10-15)

### Main task for this version

### Updates for **GRASS 8.4**
o `addLocationProject()` adds either a `project` or `location` argument to a `list` to be passed to `rgrass::execGRASS()`.  
o `project()` work with **GRASS** 8.4.  
o `.vAttachDatabase()` no longer has the `"o"` flag when calling `v.db.connect` when running **GRASS** >=8.4.  

### Potentially code-breaking changes
o `aggregate()` no longer has the `dissolve` argument for `GVector`s (polygons will always be dissolved).  
o `combineCats()` has been renamed `concats()` to align with **terra**.  
o `intercept()`, `slope()`, `r2()`, and `tvalue()` have been replaced by the single function `regress()` to align with **terra**.  
o `pca()` has been renamed `princomp()`.  

### Enhanced functionality and new functions
o `extract()` now automatically projects a `GVector` to match the CRS of a `GRaster` from which extraction is being made.  
o `grassGUI()` allows users to start the **GRASS** GUI.  
o `grassHelp()` shows the manual page for a **GRASS** module.  
o `layerIndex()` allows a `negate` argument to get the "opposite" indices of a `GRaster`.  
o `init()` assigns to `GRaster` cells the value of their coordinates, rows, columns, or values in a regular or chessboard-like pattern.  
o `regress()` replaces individual functions `intercept()`, `slope()`, `r2()`, and `tvalue()`.  
o `subset()` subsets layers of a `GRaster` or rows/geometries of a `GVector`.  
o `segregate()` creates one layer per unique value in an input `GRaster`, with values in the output coded 1 or 0 depending on whether cells in the input had the unique value or not.  

### Bug and issue fixes
o `appFuns()` succeeds in opening a **shiny** table with `app()` functions.  
o `categories()` correctly assigns active category column.  
o `crds()` correctly returns coordinates from a "points" `GVector`.  
o `distance()` correctly parses distance matrix.  
o `simplifyGeom()` works for 2-dimensional `GVector`s.  
o `flow()` creates a scratch folder when none is provided.

o `rasterize()` works when `by` is not `NULL`.  
o `.layerIndex()` (called by `categories()` and other functions related to categorical `GRaster`s) does not fail.  
o `.vHasDatabase()` correctly detects if a vector has a database attached to it.  
o Removed all instances of `sQuote()`.
