Plot Time Series of Coral Cover by Group and Depth

plot_group.Rd

Plot Coral Cover Time Series by Group

Usage

plot_group(df)

Arguments

df

A data frame containing at least the following variables:

  • year – survey year (numeric)

  • COVER – coral cover proportion (0–1)

  • reef – reef identifier

  • site – site identifier

  • survey_depth – depth category (character or numeric)

  • point_machine_classification – benthic classification label

Value

A ggplot object showing coral cover over time, faceted by reef and coloured by site.

Details

Generates a faceted time‐series plot of coral cover (%) for a given subset of the dataset. The plot shows temporal dynamics across sites, grouped by machine classification (e.g., HCC, SC, MA) and survey depth. A dynamic colour palette is used so that site colours adjust automatically to the number of unique sites present in the data slice.

This function:

  • creates a dynamic site-level colour palette using scales::hue_pal()

  • plots coral cover time series at the site level

  • facets results across reefs for visual comparison

  • automatically labels panels with depth and classification group
