mapview 0.5.0

I have put some more effort into mapview.
The current version 0.5.0 has some new features which make the whole experience much more user-friendly.

In a nutshell, changes/additions are as follows:

  • mapView() is now also defined for SpatialPixelsDataFrame
  • all Spatial * DataFrame methods have gained argument zcol to select specific columns from the attribute table
  • SpatialPointsDataFrame method has gained argument radius to scale the circles according to another variable
  • added viewRGB() to render true-/false-color images of RatserStacks/Bricks (like raster::plotRGB)
  • added viewExtent() to view the extent/bbox of Raster/Spatial objects. This is useful for large objects as only the four corners of the extent need to be reprojected (using raster::projectExtent)
  • defined '+'-method to easily add layers to a leaflet/mapview map or combine existing maps
  • defined class 'mapview' which has two slots
    • @object – a list with all objects that are shown on the map
    • @map – the map
  • Raster* methods have gained argument maxpixels to avoid long rendering times (by default set to 500000 pixels which produces acceptable times on my machine)
  • enhanced leaflet integration so that you can use leaflet maps and add features using mapview (e.g. +) or use mapview to create maps and add functionality provided by leaflet (using e.g. %>%)

As an example, this means that you can now do things like

mapView(meuse.grid, zcol = "soil") + viewExtent(meuse) + meuse

to view all points of meuse plus their extent on top of a raster layer of meuse.grid$soil

All new functionality is highlighted in detail in the demo at
