View mode options — tm

View mode options. These options are specific to the view mode.

Usage

tm_view(
  use_browser,
  use_WebGL,
  control.position,
  control.bases,
  control.overlays,
  set_bounds,
  set_view,
  set_zoom_limits,
  use_circle_markers,
  leaflet.options,
  ...
)

Arguments

use_browser: If TRUE it opens an external browser, and FALSE (default) it opens the internal IDEs (e.g. RStudio) browser.
use_WebGL: use webGL for points, lines, and polygons. This is much faster than the standard leaflet layer functions, but the number of visual variables are limited; only fill, size, and color (for lines) are supported. By default TRUE if no other visual variables are used.
control.position: position of the control attribute
control.bases: base layers
control.overlays: overlay layers
set_bounds: logical that determines whether maximum bounds are set, or a bounding box. Not applicable in plot mode. In view mode, this is passed on to setMaxBounds()
set_view: numeric vector that determines the view. Either a vector of three: lng, lat, and zoom, or a single value: zoom. See setView(). Only applicable if bbox is not specified
set_zoom_limits: numeric vector of two that set the minimum and maximum zoom levels (see tileOptions()).
use_circle_markers: If TRUE (default) circle shaped symbols (e.g. tm_dots and tm_symbols) will be rendered as addCircleMarkers() instead of addMarkers(). The former is faster, the latter can support any symbol since it is based on icons
leaflet.options: options passed on to leafletOptions()
...: to catch deprecated arguments
