Package index
Core workflow
Main entry points for generating two-level exploded-view maps from projected sf data or state-level TIGER/Line inputs.
-
explode_sf() - Explode any sf object with an existing grouping column
-
explode_sf_with_lookup() - Explode any sf object using an external lookup table
-
explode_state() - Explode a US state from TIGER/Line data
Interactive focus maps
htmlwidgets and Shiny helpers for selected-feature focus, labels, and non-blocking information cards.
-
focus_map()focusmapOutput()renderFocusmap() - Interactive focus-map viewer
Grouped layouts
Functions for three-level grouped layouts with anchor placement and optional collision-aware refinement.
-
explode_grouped() - Create a three-level grouped exploded map
-
layout_regions() - Compute region anchor positions for grouped layouts
-
estimate_block_radii() - Estimate block radius for each region
Statistics and calibration
Tools for computing geometry statistics, deriving parameters, and building calibration summaries across datasets.
-
compute_stats() - Compute geometry statistics for parameter derivation
-
derive_params() - Derive displacement parameters from geometry statistics
-
calibration_row() - Extract calibration row from an exploded_map
-
export_topojson() - Export an exploded map as TopoJSON
-
cache_list() - List cached datasets
-
cache_clear() - Clear explodemap download cache
