How can I determine the currency code for the IP address location using R?

To determine the currency code for an IP address using IP2Location.io in R, you can use the IP2Location.io API to retrieve geolocation and related data.

  1. We'll assume that you have already installed R & RStudio and we won't cover that here. You will also need a paid subscription to the Plus plan or higher. Subscribe now!
  2. In the R Console, run the command below to install the dependencies if you don't have them installed.
    R 
    
install.packages(c("httr", "jsonlite"))
  3. Save the below code into a file called test.R on your computer.
    R 
    
library(httr)
library(jsonlite)

ip = "8.8.8.8"
key = "YOUR_API_KEY"
res <- GET("https://api.ip2location.io/",
           query = list(format = "json", ip = ip, key = key))

if (res$status_code == 200) {
  raw <- rawToChar(res$content)
  data <- fromJSON(raw)
  if (!is.null(data$country)) {
    print(paste0("The currency code for IP ", ip, " is ", data$country$currency$code, "."))
  } else{
    print("ERROR: The currency code field requires a paid subscription to the Plus plan or higher.")
  }
} else if ((res$status_code == 400) || (res$status_code == 401)) {
  raw <- rawToChar(res$content)
  data <- fromJSON(raw)
  if (!is.null(data$error)) {
    print(paste0("ERROR: ", data$error$error_message))
  } else {
    print(data)
  }
} else {
  print(paste0("ERROR: ", res$status_code))
}
  4. In the RStudio, open the test.R, select all of the codes and run them.

This script will output the currency code of specified IP address. Make sure to replace 8.8.8.8 with the IP address you want and replace YOUR_API_KEY to your own API key.
