Summarize the transformations in a CoDa model (internal)

Extract from a CoDa model estimated by lm() all information related to the log-ratio transformations of the variables and the parameters.

Usage

transformationSummary(lm_res)

Arguments

lm_res

class "lm"

Value

data.frame, with list columns

Details

The structure of the return value resembles a data.frame where most columns are lists instead of vectors. The rows in this data.frame correspond to the variables used for fitting the model. The columns store information on the log-ratio transformations and their associated bases (K and F). Additionally the clr parameters and the covariance matrices are retained.
