Overview

aelab is an R package for aquatic ecology data analysis. It provides tools for:

1. GHG flux calculation — process raw data from LI-COR and LGR gas analyzers, calculate chamber flux, convert units, compute Minimum Detectable Flux (MDF), and aggregate to CO₂-equivalents.
2. Net ecosystem metabolism (NEM) — calculate gross primary production (GPP), ecosystem respiration (ER), and net ecosystem production (NEP) from high-frequency dissolved oxygen data.
3. Statistical analysis — descriptive statistics, outlier detection, normality testing, data transformation, one-way ANOVA (Tukey HSD), and Kruskal-Wallis (Dunn post-hoc) with compact letter display.
4. Visualization — ggplot2-based plot wrappers (point, line, box, bar) with a consistent theme and custom colour palettes.
