Creates an interactive map (based on latlon) from a genlight object

Description

Creates an interactive map (based on latlon) from a genlight object

Usage

gl.map.interactive(
  x,
  matrix = NULL,
  standard = TRUE,
  symmetric = TRUE,
  pop.labels = TRUE,
  pop.labels.cex = 12,
  ind.circles = TRUE,
  ind.circle.cols = NULL,
  ind.circle.cex = 10,
  ind.circle.transparency = 0.8,
  palette_links = NULL,
  leg_title = NULL,
  provider = "Esri.NatGeoWorldMap",
  verbose = NULL
)

Arguments

x	A genlight object (including coordinates within the latlon slot) [required].
matrix	A distance matrix between populations or individuals. The matrix is visualised as lines between individuals/populations. If matrix is asymmetric two lines with arrows are plotted [default NULL].
standard	If a matrix is provided line width will be standardised to be between 1 to 10, if set to true, otherwise taken as given [default TRUE].
symmetric	If a symmetric matrix is provided only one line is drawn based on the lower triangle of the matrix. If set to false arrows indicating the direction are used instead [default TRUE].
pop.labels	Population labels at the center of the individuals of populations [default TRUE].
pop.labels.cex	Size of population labels [default 12].
ind.circles	Should individuals plotted as circles [default TRUE].
ind.circle.cols	Colors of circles. Colors can be provided as usual by names (e.g. "black") and are re-cycled. So a color c("blue","red") colors individuals alternatively between blue and red using the genlight object order of individuals. For transparency see parameter ind.circle.transparency. Defaults to rainbow colors by population if not provided. If you want to have your own colors for each population, check the platypus.gl example below.
ind.circle.cex	(size or circles in pixels ) [default 10].
ind.circle.transparency	Transparency of circles between 0=invisible and 1=no transparency. Defaults to 0.8.
palette_links	Color palette for the links in case a matrix is provided [default NULL].
leg_title	Legend's title for the links in case a matrix is provided [default NULL].
provider	Passed to leaflet [default "Esri.NatGeoWorldMap"].
verbose	Verbosity: 0, silent or fatal errors; 1, begin and end; 2, progress log; 3, progress and results summary; 5, full report [default 2, unless specified using gl.set.verbosity].

Details

A wrapper around the leaflet package. For possible background maps check as specified via the provider: http://leaflet-extras.github.io/leaflet-providers/preview/index.html

The palette_links argument can be any of the following: A character vector of RGB or named colors. Examples: palette(), c("#000000", "#0000FF", "#FFFFFF"), topo.colors(10)

The name of an RColorBrewer palette, e.g. "BuPu" or "Greens".

The full name of a viridis palette: "viridis", "magma", "inferno", or "plasma".

A function that receives a single value between 0 and 1 and returns a color. Examples: colorRamp(c("#000000", "#FFFFFF"), interpolate = "spline").

Value

plots a map
