occCite (version 0.5.1)

occCiteMap: Generating a map of downloaded points

Description

Makes maps for each individual species in an occCiteData object.

Usage

occCiteMap(
  occCiteData,
  species_map = "all",
  species_colors = NULL,
  ds_map = c("GBIF", "BIEN"),
  map_limit = 1000,
  awesomeMarkers = TRUE,
  cluster = FALSE
)

Arguments

occCiteData

An object of class occCiteData to map

species_map

Character; either the default "all" to map all species in occCiteData, or a subset of these specified as a character or character vector.

species_colors

Character; the default NULL will choose random colors from those available (see Details), or those specified by the user as a character or character vector (the number of colors must match the number of species mapped).

ds_map

Character; specifies which data service records will be mapped, with the default being GBIF, BIEN, and GBIF_BIEN (records with the same coordinates in both databases).

map_limit

Numeric; the number of points to map per species, set at a default of 1000 randomly selected records; users can specify a higher number, but be aware that leaflet can lag or crash when too many points are plotted.

awesomeMarkers

Logical; if TRUE (default), mapped points will be awesomeMarkers attributed with an icon for a globe for GBIF, a leaf for BIEN, or a database if records from both databases have the same coordinates; if FALSE, mapped points will be leaflet circleMarkers

cluster

Logical; if TRUE (default is FALSE) turns on marker clustering, which does not preserve color differences between species

Value

A leaflet map

Details

When mapping using awesomeMarkers (default), the parameter species_colors must match those in a specified color library, currently: c("red", "lightred", "orange", "beige", "green", "lightgreen", "blue", "lightblue", "purple", "pink", "cadetblue", "white", "gray", "lightgray"). When awesomeMarkers is FALSE and species_colors are not specified, random colors from the RColorBrewer Set1 palette are used.

Examples

# NOT RUN {
data(myOccCiteObject)
occCiteMap(myOccCiteObject, cluster = FALSE)
# }
