Plot Dual-Pool Logistic Decomposition

Visualizes the rapid pool, slow pool, total predicted gas production, and observed gas production for a fitted dual-pool logistic model.

Usage

plot_dual_pools(fit, head = NULL, treatment = NULL)

Arguments

fit

A dual_logistic_fit object.

head

Optional bottle identifier. If supplied, only that bottle will be plotted.

treatment

Optional treatment name. If supplied, a representative bottle from that treatment will be plotted.

Value

A ggplot2 object.

Details

The plot helps interpret the relative contributions of rapidly and slowly fermentable fractions through time.

Components displayed include:

• Observed gas production

• Predicted total gas production

• Rapid fermentation pool

• Slow fermentation pool

This visualization is useful for understanding substrate heterogeneity and fermentation dynamics.
