build_composition_df R Documentation
Build a body-composition data frame from a list of composition results
Description
Internal helper shared by analyze_composition_by_size() and
analyze_composition_changes(). Converts a list of
calculate_body_composition() outputs into a tidy data frame,
avoiding duplication of the identical sapply + data.frame
block.
Usage
build_composition_df(compositions, weights)
Arguments
compositions
List of results from calculate_body_composition(),
one element per weight point or time step.
weights
Numeric vector of fish weights corresponding to each element.
Value
Data frame with columns Weight, Water_g,
Protein_g, Ash_g, Fat_g, and the corresponding
*_fraction and Energy_density columns.
