What's next in googleway: legends

Due: version 2.4

In a previous post I introduced colours to googleway. That's amazing, I hear you say! What's even more amazing is that now you can see what those colours represent through legends. 

## until v2.4 is released you'll need the development version
devtools::install_github("SymbolixAU/googleway")
library(googleway)

mapKey <- 'your_api_key'

## using the default legend
google_map(key = mapKey) %>%
  add_polygons(data = melbourne, polyline = "polyline", 
               fill_colour = "SA4_NAME", fill_opacity = 0.8,
               stroke_colour = "SA4_NAME", legend = T)

And you can specify various options through the legend_options argument.

## currently available options: position, css, title, reverse, prefix and suffix
legendOptions <- list(
  position = "RIGHT_TOP",
  css = "max-width: 200px; max-height: 300px",
  title = "Statistical Area 4"
)

google_map(key = mapKey) %>%
  add_polygons(data = melbourne, polyline = "polyline", 
               fill_colour = "SA4_NAME", fill_opacity = 0.8,
               stroke_colour = "SA4_NAME", legend = T, 
               legend_options = legendOptions)
