In grec: Gradient-Based Recognition of Spatial Patterns in Environmental Data

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 tif 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 improvments 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• thresholds argument has been replaced by qLimits.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.
