obs_complex_species_pie.Rdobs_complex_species_pie(data, threshold_prop_other = 0.05, plot_dir = NULL)A list containing the following named elements: - `data.req`: A data frame with observation data. Must contain a column named after the pattern `"<varname>.den"` (e.g., `"psrous_rate.den"`), which stores the observation counts per species. - `varname`: A character string indicating the base name of the observation variable (used to identify the column `<varname>.den` in the data). - `nice_varname`: A character string used for naming the saved output file.
A numeric threshold (between 0 and 1) indicating the minimum proportion of total observations required for a species or complex to appear as its own slice in the pie chart. Species below this threshold are grouped under "Other". Default is `0.05` (1
plot_dirOptional. A character string giving the directory path where the HTML version of the pie chart should be saved. If `NULL`, the chart is not saved. Default is a specific folder on the user's system.
An interactive pie chart (`plotly` object) showing the distribution of observations by species or species complex. If `plot_dir` is provided, the chart is also saved as an HTML file. This function creates an interactive pie chart that shows the distribution of observations by species or species complexes, based on a specified observation variable from a pre-processed dataset. It optionally groups species with a small proportion of observations into a single "Other" category, and can save the plot as an HTML file for sharing or embedding. - Species names starting with `"unlabel_"` are treated as complexes and labeled accordingly. - The observation variable used in the calculation must match the pattern `<varname>.den`. - The pie chart uses `plotly` for interactive visualization and `htmlwidgets` to export.
