dragmapr 0.1.0

Initial CRAN release.

  • drag_map_prototype() writes a self-contained D3 browser helper where grouped sf regions, labels, and annotation boxes can be dragged freely. It exports region and label offset CSVs.
  • render_dragged_map() reconstructs the dragged layout as a ggplot2 image from the source geometry plus offset tables.
  • render_dragmapr_project() renders a complete Spatial Studio project bundle (ZIP) in one call.
  • make_region_labels(), as_drag_labels(), and as_drag_annotations() build label tables; read_label_state() and apply_label_state() restore saved label positions.
  • read_offsets() and apply_offsets() handle region offset I/O.
  • read_dragmapr_sf_upload(), read_dragmapr_sf_url(), and prepare_dragmapr_sf() read and normalise spatial files for Shiny workflows.
  • dragmapr_iframe_bridge() provides the JavaScript bridge for relaying drag state from the helper iframe back to Shiny inputs.
  • dragmapr_addin() registers an RStudio gadget under Addins > Launch dragmapr that embeds the prototype in the viewer pane and assigns region_offsets and label_offsets to the target environment on completion (.GlobalEnv when launched from the RStudio Addins menu).
  • Interactive and static outputs support selective legend and label rendering with legend_values and label_values, preserving stored offsets for hidden labels.
  • Label connector lines can be styled by color, width, line pattern, and arrow endpoint in both the browser helper and static exports.
  • Movement context controls can show origin outlines, movement connector lines, and browser-only drag preview trails. Movement connectors support configurable color, opacity, width, line pattern, and open/closed endpoints.
  • Spatial Studio demonstrates legend and label multiselect filters, connector styling, movement context controls, project persistence, and static bundle export.
  • Release hardening: package-internal %||% is defined for the RStudio addin, prototype output defaults to a temporary HTML file unless file is supplied, connector linetypes are validated in static exports, the Shiny iframe bridge stops polling on disconnect/unload, CRS-less inputs warn before assuming the target CRS, legacy label helper aliases emit deprecation warnings, and the bundled D3 license is included under inst/prototype/.
