shift: Shift data to origin given by p
In jsilve24/philr: Phylogenetic partitioning based ILR transform for metagenomics data
shift R Documentation
Shift data to origin given by p
Description
Shift must be applied before transformation
Usage
shiftp(x, p)
shiftpInv(y, p)
Arguments
x
closed compositional data matrix (or vector)
p
weights (should not be closed)
y
the shifted composition output by shiftp
Value
shifted data matrix y (no closure is applied) rows are
samples, columns are parts

c <- t(rmultinom(10,100,c(.1,.6,.2,.3,.2))) + 0.65 # add a small pseudocount
x <- miniclo(c)
shiftp(x, p)
