Generating a downloadable Quarto document from a shiny app on shinyapps.io
Generating a downloadable Quarto document from a shiny app on shinyapps.io
The following shiny app is intended pass user inputs from the app into a parameterized html quarto document that, when rendered, is downloaded via downloadHandler() and downloadButton(). This reproducible example works perfectly when deployed locally, but not when hosted on shinyapps.io. My understanding is that the quarto::quarto_render() call should have permission to write a file on shinyapps.io (it wouldn't be persistent from instance to instance, but that's fine). Does shinyapps.io not supp...

Zoom levels - Leaflet - a JavaScript library for interactive maps
Zoom levels - Leaflet - a JavaScript library for interactive maps
To understand how zoom levels work, first we need a basic introduction to geodesy.
When we represent the world at zoom level zero, it’s 256 pixels wide and high. When we go into zoom level one, it doubles its width and height, and can be represented by four 256-pixel-by-256-pixel images:
At each zoom level, each tile is divided in four, and its size (length of the edge, given by the tileSize option) doubles, quadrupling the area. (in other words, the width and height of the world is 256·2zoomlevel pixels):
In technical terms, the cylindrical projection that Leaflet uses is conformal (preserves shapes), but not equidistant (does not preserve distances), and not equal-area (does not preserve areas, as things near the equator appear smaller than they are).
setView(center, zoom), which also sets the map center flyTo(center, zoom), like setView but with a smooth animation zoomIn() / zoomIn(delta), zooms in delta zoom levels, 1 by default zoomOut() / zoomOut(delta), zooms out delta zoom levels, 1 by default setZoomAround(fixedPoint, zoom), sets the zoom level while keeping a point fixed (what scrollwheel zooming does) fitBounds(bounds), automatically calculates the zoom to fit a rectangular area on the map
