Produce an interactive html map

Description

Produce an interactive html map.

Usage

interactive_map(
  ras,
  layer_name = NULL,
  palette = "inferno",
  transparency = 0.8,
  legend = TRUE,
  set_value_range = NULL,
  discrete = FALSE,
  scale_type = "none",
  outfile = NULL,
  surveillance_locs = NULL,
  pt_col = "red",
  cleanup = FALSE
)

Arguments

`ras`	A `RasterLayer` or file path to a raster file.
`layer_name`	Character. An optional name to assign to `ras`.
`palette`	Either a vector of 2 or more colours (e.g. as hex codes or colour names) or the name of a palette function supported by `tmap` (see `tmaptools::palette_explorer()` and `tmap::tm_raster()`).
`transparency`	Numeric. Value between 0 and 1 defining the opacity of the plotted raster data (1 = fully opaque; 0 = fully transparent).
`legend`	Logical. Should a legend be plotted?
`set_value_range`	A numeric vector giving upper and lower limits for raster values. Values outside this range (including the limits) will be set to NA.
`discrete`	Logical. Are the values of `ras` discrete (categorical)?
`scale_type`	Character. Can be one of: `"none"` (raw data, no rescaling), `"log10"`, `"max normalize"` (proportional to maximum value), `"minmax normalize"` (rescale values to be between 0 and 1 based on min and max) or `"logit"`. Note that if `"log10"` or `"logit"` is used, 0 or 1 values must be masked ( using `set_value_range`) or rescaled before passing to this function. `scale_type` is ignored if `discrete` is `TRUE`.
`outfile`	Character. If `NULL`, map will be returned to R and not saved. Otherwise, map will be exported as a html file. Full path address must be used. If pandoc is available, a standalone html file is created (see details).
`surveillance_locs`	A spatial object or a path to a .csv file containing columns named "Latitude" and "Longitude".
`pt_col`	Character. The plotting colour for surveillance points.
`cleanup`	Logical. If a standalone html file is created, should accessory files be removed after the standalone file is generated? This will be a folder created within `tempdir()`.

Details

To create a standalone html file, the pandoc software must be installed and available to R. If pandoc is unavailable, the html file will be accompanied by a folder of accessory files.
