Overview

About

Maintained by George ArthurCRAN page ↗GitHub ↗Website ↗Issues ↗

Creates interactive draggable plots from grouped projected 'sf' geometry. The primary deliverable is a browser-based 'D3' helper where regions and labels can be moved freely; users drag, then copy or download the resulting offset tables. Labels can be derived automatically with make_region_labels(), supplied directly with as_drag_labels(), and their moved positions saved and restored with read_label_state() and apply_label_state(). Hierarchical spatial datasets are supported via hierarchy detection, upload profiling, make_hierarchy_key(), and inherit_layout(), which recommend parent-child groupings and propagate parent-level drag offsets to finer child groupings. Automatic starting layouts are provided by suggest_offsets() using radial, grid, or directional algorithms. Spatial file diagnostics are available through dragmapr_diagnostics(). When a reproducible static image is also needed, render_dragged_map() reconstructs the layout as a 'ggplot2' plot from the source geometry plus the exported offset tables. Project bundles can be written with write_dragmapr_project() and rendered with render_dragmapr_project(). The interactive layer is built on the 'D3' library: Bostock, Ogievetsky and Heer (2011) doi:10.1109/TVCG.2011.185. Spatial data handling uses the 'sf' package: Pebesma (2018) doi:10.32614/RJ-2018-009.

Changes in 0.2.0

drag_map_prototype() gains an optional transition argument: the browser helper runs one client-side leaf-flip branch animation for parent-to-child bloom and child-to-parent unbloom, and draws a dotted group-drag boundary per expanded group. Clicking a boundary posts a dragmapr-collapse-branch message to the embedding page, or resets the branch when the helper runs standalone; a plain click on a region posts dragmapr-region-click.
New inst/examples/branch-bloom-tester.R Shiny example isolates the branch-bloom helper so clean bloom and leaf-flip behavior can be tested without the full Spatial Studio shell.
New packaged cheatsheet in inst/cheatsheets/ covers the core workflow, labels, static rendering, Spatial Studio, hierarchy/bloom helpers, CRS diagnostics, layout snapshots, and transition utilities.

New upload intelligence helpers: detect_hierarchy_columns(), recommend_dragmapr_hierarchy(), validate_bloom_hierarchy(), build_branch_transition_data(), make_branch_bloom_labels(), summarise_spatial_crs(), and profile_spatial_upload() move parent/child detection, CRS meaning, branch-bloom data prep, and safe parent-first label setup into reusable package functions.
Spatial Studio: new **Bloom** sidebar section. Pick a child column ("bloom into"), then click a parent region on the map (or choose parents in the panel) to expand just that parent into its children with a leaf flip - the rest of the map keeps the parent grouping. At most two parents can be expanded at a time (expanding another replaces the oldest), the dotted reset boundary can be toggled off, and clicking the boundary or the children compresses the branch and restores the parent's saved position. The bloom target must genuinely nest inside the current grouping (data-driven check with a clear error otherwise). Arming bloom embeds both parent and child keys in the helper once; expanding and collapsing then run fully client-side over postMessage, so there is no iframe rebuild, no loading overlay, and the animation always plays. The dotted frame is also the group's drag handle: dragging it moves the whole expanded branch (children, labels, and frame together), and collapsing places the parent at the mean of its children's positions. With "Dissolve to parent shells when collapsed" (on by default), child-level uploads display as clean dissolved parent outlines until a parent blooms, which both sharpens the reveal and reduces the number of drawn shapes.
Spatial Studio: the Bloom panel now includes an animation selector so users can switch between the leaf-flip proxy animation and the clean branch-bloom animation. The selected mode is sent to the live helper without rebuilding the iframe.
Spatial Studio: one unified full-app busy veil replaces the previous mix of map overlay, sidebar freeze, and full veil. Two modes share the same blocker - "Loading spatial data" (uploads, project opens) and "Processing changes" (helper rebuilds) - with lock counting so overlapping tasks never hide the veil early, a short show delay so fast rebuilds don't flash, and safety timers so a missed release can never freeze the app. The Shiny busy state only drives the slim top progress bar; client-side bloom interactions never show a veil.
Spatial Studio fixes for files with arbitrary column names: hierarchy detection on column switches is data-driven (the child column must actually nest inside the parent grouping), and the default group/region column detection no longer assumes specific column names or excludes one-row-per-region files (e.g. COUNTY_NAM instead of COUNTY).

Install

R (CRAN)pak (dev)Ubuntu (r2u)Fedora (COPR)openSUSE (OBS)

install.packages("dragmapr", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("PrigasG/dragmapr")

Development version from PrigasG/dragmapr. Installs pak first if it is not already available.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-dragmapr

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled. We list this channel from recorded r2u download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.

bspm (used by r2u) also needs make: sudo apt install make

# enable the iucar/cran COPR if it is not already present, then install
ls /etc/yum.repos.d/*iucar*cran*.repo >/dev/null 2>&1 \
  || sudo dnf copr enable -y iucar/cran
sudo dnf install -y R-CRAN-dragmapr

RPMs from the iucar/cran COPR, rebuilt from CRAN.

For install.packages() integration in R, also: sudo dnf install R-CoprManager

# add the autoCRAN OBS repo (Tumbleweed) if it is missing, then install
zypper -q lr | grep -qi autoCRAN \
  || sudo zypper addrepo https://download.opensuse.org/repositories/devel:/languages:/R:/autoCRAN/openSUSE_Tumbleweed/devel:languages:R:autoCRAN.repo
sudo zypper install -y R-dragmapr

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed). We list this channel from recorded autoCRAN download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.
