digitize: Easy digitizing of vector features within your rstudio session (or any browser)

Description

digitize is based on the leaflet draw plugin. It provides a bunch of leaflet maps as base layers for digitizing vector features.

Usage

digitize(mapCenter = NULL, zoom = 15, line = TRUE,
  rectangle = TRUE, poly = TRUE, circle = TRUE, point = TRUE,
  remove = TRUE, position = "topright",
  maplayer = c("CartoDB.Positron", "OpenStreetMap", "Esri.WorldImagery",
  "Thunderforest.Landscape", "OpenTopoMap"), overlay = NULL,
  features = NULL, preset = "all", locPreset = "muf", cex = 10,
  lwd = 2, alpha = 0.6, opacity = 0.7)
