The goal of leaflethex is to create hexbin layers that can be added to plots made with the leaflet package.
This is a work in progress and is not yet a functional R package. Stay tuned!
You can install the released version of leaflethex from CRAN with:
And the development version from GitHub with:
# install.packages("devtools") devtools::install_github("rpruim/leaflethex")
This is a basic example which shows you how to add the hexbin layer to your leaflet map:
library(leaflethex) df = tibble( lat = rnorm(100), lng = rnorm(100) ) map <- leaflet::leaflet(df) %>% leaflet::addTiles() %>% leaflethex::add_hexbin( radius = 19, lowEndColor = "yellow", highEndColor="red") map
Parameters for add_hexbin
data- data frame or tibble - alternate data to use for this hexbin instead of default map data
radius- numeric - choose the base size for the hexagons
opacity- decimal - between 0.0 and 1.0 - choose the percent of opacity for the hexagons
duration- numeric - positive milliseconds taken by the renderer to draw the hexagons
lowEndColor- string - choose the color for the smaller hexagons
highEndColor- string - choose the color for the larger hexagons
Note About Coloring - For best readable results, use colors that have high contrast in hue and shade such as red and yellow. White is generally a safe option for the
lowEndColor, but the eye is better at picking up changes in hue than changes in shade.
uniformSize- boolean - choose if the size of the hexagons should be uniform or variable
uniformColor- string - choose a color to be uniform across the different sizes of hexagons instead of variable color
sizeSummaryFunction- string - choose a function from ‘count’, ‘sum’, ‘max’, ‘min’, ‘mean’, or ‘median’ or give a valid JS function (in development)
sizevar- string - the name of the variable used to calculate the size of the hex using the
colorSummaryFunction- string - choose a function from ‘count’, ‘sum’, ‘max’, ‘min’, ‘mean’, or ‘median’ or give a valid JS function (in development)
colorvar- string - the name of the variable used to calculate the color of the hex using the
