plot_delta_comp {codaredistlm}

Plot redistributed time-use predictions from compositional ilr multiple linear regression model fit

Description

Plot redistributed time-use predictions from compositional ilr multiple linear regression model fit by predict_delta_comps()

Usage

plot_delta_comp(dc_obj, comp_total = NULL, units_lab = NULL)

Arguments

dc_obj

A deltacomp_obj object returned from the function predict_delta_comps

comp_total

A numeric scalar that is the original units of the composition to make the x-axis the original scale instead of in the range [min(delta), max(delta)] in (-1, 1).

units_lab

Character string of the units of the compositions relating to comp_total to add to the x-axis label

Value

Returns a plot object from the ggplot2 package (that is, class of gg and ggplot).
