get.l: Generate a vector of weight transformation values from l.min...

In EMMAgeo: End-Member Modelling of Grain-Size Data

Generate a vector of weight transformation values from l.min to l.max.

Description

This function generates a sequence of weight transformation values that range from l_min (by default zero) to l_max (by default 95 % of the maximum possible value). It uses the function test.l.max().

Usage

get.l(X, n = 10, max = 0.95, min = 0)

Arguments

X	Numeric matrix, input data set with m samples (rows) and n variables (columns).
n	Numeric scalar, length of the output vector (by default 10).
max	Numeric scalar, fraction of the maximum value (by default 0.95).
min	Numeric scalar, minimum value (by default zero).

Value

Numeric vector of class "EMMAgeo_l", weight transformation values.

Examples

## load example data set
data(example_X)

## truncate data set to save computation time, not needed in real life
X <- X[1:10, 1:10]

## infer l-vector
l <- get.l(X = X, 
           n = 5, 
           max = 0.8, 
           min = 0.02)
