plot_hex: Visualizing Point pattern

In wenlab501/EpiTrans: R package for estimation of epidemic transmissibility in time and space

Visualizing Point pattern

Description

Plot the spatial pattern of cases by hexagon-bining; aggregate the point into specified hexagon grids

Usage

plot_hex(
  x,
  y,
  Rj = NULL,
  grid.n = 50,
  crs = NULL,
  bnd = NULL,
  basemap = NULL,
  interact = TRUE,
  gridLonLat = TRUE,
  title = ""
)

Arguments

x	Vector of x coordinates of data points.
y	Vector of y coordinates of data points.
Rj	Vector of individual reproductive numbers of data points.
grid.n	Number of grid cells in one direction (shorter side).
crs	Coordinate reference system of data points: numeric (EPSG code), object of class 'crs', or input string for st_crs; if NULL, using CRS of basemap, or using WGS84 (EPSG:4326).
bnd	A 4-length numerical vector of the form c(xmin, ymin, xmax, ymax) which gives the number of x and y coordinates' ranges of the map.
basemap	Object of class 'sf'; basemap plotting on map.
interact	Logical; if TRUE, plot thematic interactive map; if FALSE, static plotting non-interactive thematic map.
gridLonLat	Logical; draw latitude and longitude grid on non-interactive map.
title	Main title of plot.

Examples

data("EpiTrans")

plot_hex(x = dengue$long, y= dengue$lat, grid.n=30, basemap = Taiwan)
