orthus_lr_transforms {fido}

Log-Ratio transforms for orthus objects

Description

Log-Ratio transforms for orthus objects

Usage

oglr(x, s, V)

oglrInv(x, s, V)

oalr(x, s, d = NULL)

oalrInv(y, s, d = NULL)

oilr(x, s, V = NULL)

oilrInv(y, s, V = NULL)

oclr(x, s)

oclrInv(x, s)

Arguments

x

orthus data array (e.g., first s rows are multinomial parameters or log-ratios)

s

first s rows of x are transformed

V

transformation matrix (defines transform)

d

for ALR, which component (integer position) to take as reference (default is ncol(x)) for alrInv corresponds to column position in untransformed matrix.

y

orthus data array (e.g., first s rows are multinomial parameters or log-ratios)

Value

A matrix
