array_lr_transforms: Log-Ratios Transforms for Arrays

In jsilve24/driver: Utility Functions from Justin Silverman

Description

Extension of base_lr_transforms to arrays over arbitrary margins.

Usage

glr_array(x, V, parts, dimname = colnames(V))

glrInv_array(y, V, coords, dimname = rownames(V))

alr_array(x, d = dim(x)[parts], parts)

alrInv_array(y, d = dim(y)[coords] + 1, coords)

ilr_array(x, V = NULL, parts)

ilrInv_array(y, V = NULL, coords)

clr_array(x, parts)

clrInv_array(y, coords)

Arguments

x	multidimensional array in simplex
V	transformation matrix (defines transform)
parts	index of dimension of x that represents parts (e.g., compositional variables)
dimname	character vector of dimension name for resulting dimension after transformation
y	multidimensional array in transformed space
coords	index of dimension of x that represents coords (e.g., transformed variables)
d	for ALR, which component (integer position) to take as reference (default is ncol(x)) for alrInv corresponds to column position in untransformed matrix.

Details

accelerated for parts OR coords == 1

Value

array

Examples

a <- array(1:100, dim=c(10, 5, 2))
a <- miniclo_array(a, parts=2)
clr_array(a, parts=2)
