Retrieve of set of hex-binned polygons for the given xyz data

Description

Retrieve of set of hex-binned polygons for the given xyz data

Usage

st_hexbin(
  x,
  y,
  z,
  fun = c("mean", "count", "median")[2],
  crs = ifelse(use_wkt("sf"), "epsg:4326",
    "+proj=longlat +datum=WGS84 +ellps=WGS84 +towgs84=0,0,0"),
  na.rm = TRUE,
  ...
)

Arguments

x	a vector of x-locations
y	a vector of y-locations
z	a vector of values associated with each location
fun	character the function used to process the cell values currently only 'mean', 'median', or 'count' (default)
crs	the projection string
na.rm	logical passed through to user's selected function
...	further arguments for hexbin

Value

Examples

## Not run: 
xyz <- hexbin_points()
 hb <- st_hexbin(xyz$x, xyz$y, xyz$z)
 hb <- dplyr::rename(hb, count = value)
 pts <- sf::st_as_sf(xyz,
                     coords = c("x", "y"),
                     crs = "+init=epsg:4326",
                     agr = "identity")
 plot(hb, asp = 1, reset = FALSE, axes = TRUE)
 plot(pts, col = 'green', add = TRUE)
