grainSimilarity_align: Grain Type similarity matrix for DTW alignments

Description Usage Arguments Value Author(s) See Also Examples

View source: R/grainSimilarityMatrices.R

Description

Get the relative similarity matrix of grain types as used for snow profile alignments. This similarity matrix considers the formation and metamorphosis of grain types, as well as quirks of the SNOWPACK model.
grainSimilarity_evaluate is an analogous matrix designed for assessing the similarity between two profiles, which requires considering the resulting avalanche hazard implications of grain types.
The domain is [0, 1]1 representing identical grain types. The column 'NA' can be used for unknown grain types.

Usage

1

Arguments

triag

Return a triangular matrix (TRUE, default) or a symmetric matrix (FALSE)

Value

data.frame, either triangular or symmetric
