Visualize aggregated uncertain locations

Usage

plot_aggregation(
  dat_loc,
  cluster,
  is_uncertain,
  is_aggre,
  igraph_cluster = NULL,
  title = "Aggregation",
  color_mode = c("status", "cluster", "igraph"),
  palette = NULL,
  point_size = 1.5,
  aggre_size = 2.2,
  point_alpha = 1,
  legend_position = "bottom",
  strip_text_size = 16,
  legend_text_size = 12,
  legend_title_size = 12,
  background_color = "grey85",
  ...
)

Arguments

dat_loc: A numeric matrix of dimension \(n \times \rho\), where \(n\) is the number of observations and \(\rho = 2\) corresponds to two spatial coordinates.
cluster: A vector of length \(n\) giving cluster labels.
is_uncertain: A logical vector of length \(n\).
is_aggre: A logical vector of length \(n\), or a vector of indices of aggregated locations.
igraph_cluster: An optional vector of connected-component labels of length \(n\). Non-aggregated locations can be NA. If color_mode = "igraph", only aggregated locations are displayed.
title: A character string specifying the facet title.
color_mode: A character string specifying the coloring mode. Must be one of "status", "cluster", or "igraph".
palette: An optional character vector of colors for cluster or igraph labels.
point_size: A numeric value specifying the point size for background points.
aggre_size: A numeric value specifying the point size for aggregated points when highlighted.
point_alpha: A numeric value specifying the point alpha.
legend_position: A character string specifying the legend position.
strip_text_size: A numeric value specifying the facet strip text size.
legend_text_size: A numeric value specifying the legend text size.
legend_title_size: A numeric value specifying the legend title size.
...: Additional arguments passed to ggplot2::geom_point().

Value

A ggplot object.
