Occurrence points Leaflet map

Create a Leaflet map with the presence or presence/absence locations. Good for spotting problematic points.

pts_leaflet(pts, cols = NULL, cluster = FALSE, popinfo = NULL)

Arguments

pts

A data frame containing the presence or presence/absence points. The first column should be longitude (x) and the sencond latitude (y). In the case of presence/absence data, an additional collumn should be provided, coded as 0 (absence) and 1 (presence).
cols

Character string indicating the color for the points or a character vector of length 2 indicating the colors for the presence and absence, respectively. If not supplied, the default will be used.
cluster

Should the points be clustered (i.e., aggregated)? Only valid if `pts` is supplied. Default is FALSE.
popinfo

An optional vector of values to be used in the popup box when clicking in a point. Can be either a number indicating the column of the data.frame (this may be useful for e.g. showing value for a certain variable) or a character vector of length = number of points. If not supplied, the number of the row will be used (this may be useful for spotting points with problems).

Value

A Leaflet map with the points.

Examples

library(sdmvis)
# Load data
