calculate_density_matrix_grain_hardness: calculate_density_matrix_grain_hardness

In bridachristian/SnowProfileProcessing:

Description

calculate_density_matrix_grain_hardness() is a function that combine grain shapes and hardness to estimate density. The method following paper Valt e Cagnati, "Stima della densita della neve conoscendo la forma dei grani e la durezza", 2005 Neve e Valanghe,55 pag. 40-45

Usage

calculate_density_matrix_grain_hardness (merged_table, grain_shape1_colnames, grain_shape2_colnames, density_colnames, hardness_colnames)

Arguments

merged_table	A table containing stratigraphy and density information for each layer
grain_shape1_colnames	The name of column associated to grain shape 1
density_colnames	The name of column associated to Density
hardness_colnames	The name of column associated to Hardness
grain_shape1_colnames	The name of column associated to grain shape 2

Value

A list of 3 elements. The first element is a dataframe of estimated density for each pairing of grain shape and density, The second element is a dataframe of number of observation for each pairing of grain shape and density The third element is a dataframe of standard deviation of density for each pairing of grain shape and density
