maplamina

GPU-accelerated interactive maps for R (MapLibre GL + deck.gl via htmlwidgets).

Status: early / MVP. APIs may change.

• Fast: WebGL rendering with binary (typed-array) attributes for smooth interaction with millions of features.
• R-native syntax: pipe-friendly add_*() verbs plus formula mappings like radius = ~value.
• First-class components: views, filters, and summaries are built in - no more layer-control workarounds.
• Composable UI: bind components into shared controls, and mount them in an optional panel UI.
• sf-friendly: works naturally with sf objects for points, lines, and polygons.
• Quarto/R Markdown ready: designed to drop into reports and dashboards.

Installation

CRAN submission is pending. Install the development version from GitHub:

# install.packages("devtools")
devtools::install_github("jhumbl/maplamina")

Quick start (views)

A minimal example showing views switching the radius mapping:

set.seed(1)
n <- 2000
d <- data.frame(
  lon   = runif(n, -60, 60),
  lat   = runif(n, -60, 60),
  value = runif(n, 1, 10)
)

maplamina() |>
  add_circles(d, stroke = FALSE, fill_color = "darkblue") |>
  add_views(
    view("Value",         radius = ~value),
    view("Inverse Value", radius = ~(max(value) - value + 1))
  )

Other components

• add_filters()
  • filter_range() numeric slider
  • filter_select() categorical selector
• add_summaries()
  • summary_count(), summary_mean(), summary_min(), summary_max(), summary_sum()
• Tooltips/popups: tmpl()
• Optional UI: add_panel() + section() / sections()
• Legends: add_legend()

Layers

• add_circles() points/circles
• add_lines() paths/lines
• add_polygons() filled polygons (+ stroke)
• add_icons() / add_markers() point icons/markers
