algo

The algo package allows you to implement the Algolia Places Address Search Auto Completion Menu on shiny Text Inputs.

Setup

In order to use the Algolia Places JavaScript library, you’ll need create a free Places application in which you can get an ID and an API KEY. The library is free up to 1,000 requests / day which is quite cool for most users.

After that, set your credentials within the .Renviron file which can be opened with:


# install.packages("usethis")

usethis::edit_r_environ()

Then, store the value of your credentials as follows:

# These credentials are fakes and used  to give you an idea

ALGOLIA_ID= LSKDFNSFSD  

ALGOLIA_KEY= 29453SKVNEV43T3G3KVEEV

Finally, save your .Renviron file, close it and restart your R session.

Installation

You can install the development version of algo from Github with:


# install.packages("remotes")

remotes::install_github("feddelegrand7/algo")

How to use the algo package

The algo package has two functions:

use_algolia(): you must put the use_algolia() function at the beginning of your shiny UI. It doesn’t take any argument. It only allows you to activate the Algolia Places JavaScript library.
algo(): you’ll implement an address search auto completion menu on any shiny text input using this function.

Example

Run the following shiny app to get an idea about the package’s features:


library(shiny)
library(algo)


ui <- fluidPage(
  
  use_algolia(), 
  
  
  textInput(inputId = "inp1", label = "Please introduce your address", width = "800px"), 
  
  
  algo(element = "#inp1", type = "address") # Don't forget to add the # to your ID
  
)


server <- function(input, output) {




}

shinyApp(ui, server)
