1.6.2

  • Improvements on getGradients method for SpatRaster class inputs.

1.6.1

  • Minor corrections on documentation and demo files.

1.6.0

  • We are changing the name of the detectFronts function to getGradients. However, for backwards compatibility, detectFronts will still be available until v2.0.0.
  • Adding new methods for getGradients: Agenbag-1 and Agenbag-2.
  • Some minor improvements in documentation and code.

1.5.0

  • Compatibility with imagine >= 2.0.0.
  • New method for SpatRast objects (from terra package).
  • Improvements on all methods.
  • ConvolNormalization = FALSE by default now in detectFronts function.

1.3.5

  • Corrections in Belkin and O'Reilly method (GX and GY kernel orientation).
  • Adding methods for SpatRast (from terra package) objects.
  • Support for Raster- objects will be retired since next versions of grec.
  • Improving methods for array objects.
  • ConvolNormalization argument is now set as FALSE by default in detectFronts function.
  • Minor corrections and improvements in efficiency.

1.3.4

  • Improvements on the way to work with matrix, arrays, list and RasterLayer objects.
  • Correcting some bugs regarded with methods.
  • Include ConvolNormalization argument and enable normalization of convolutions as default.
  • Add documentation of methods.

1.2.2

  • Improvements on the way to extract matrix data from RasterLayer object.
  • Correcting a bug when RasterLayer has not in-memory loaded data (e.g. RasterLayer gotten from read a tiff file).
  • Add documentation for NW_USA_SST data.

1.2.1

  • Some corrections in demos.
  • Include a new example data set for SST: NW_USA_SST
  • Testing normalization inside B&O method.

1.2.0

  • Several changes and improvements on package structure.
  • finalSmooth and control arguments detectFronts were deleted.
  • extraParams function were deleted. Now, available advanced arguments will be showed in help.
  • Help document for detectFronts were updated.
  • Another little corrections and improvements.

1.1.2

  • Now, detectFronts function has the method argument, using by default the Belkin & O'Reilly (2009) algorithm.
  • Some little corrections.

1.1.1

  • Modifications on the title of package.
  • New set of exampling data (grecExData).
  • Changes how the detectFronts algorithm works internally.

1.1.0

  • Change function name: from fromDetection to detectFronts.
  • Change several argument names on detectFronts function.
  • thresholds argument has been replaced by qLimits. Check help of detectFronts function for details.
  • On detectFronts function, the final smooth application is optional now, controling by finalSmooth argument.
  • Now detectFronts is a method for classes: matrix, array and RasterLayer.
  • Bugs and corrections.

1.0.0
