Computation of the set of pivot logratios(PLRs) based on the specified ordering of parts
PLR(data, ordering=1:ncol(data), weight=TRUE)
data |
A compositional data frame or matrix |
ordering |
The ordering of the parts to be used in the PLRs (by default, the original ordering of the columns) |
weight |
Logical indicating if varying weights are returned (default: |
The function PLR
computes the set of pivot logratios according to the ordering of the parts.
LR |
The pivot logratios (PLRs) |
LR.wt |
