dtmapi

Introduction

The dtmapi package provides functions to interact with the Displacement Tracking Matrix (DTM) API. This vignette demonstrates how to use the package’s functions to fetch data from the API. The functions covered include:

get_all_countries()
get_all_operations()
get_idp_admin0_data()
get_idp_admin1_data()
get_idp_admin2_data()

Install Package

The dtmapi package is available on CRAN and can be installed using the following command: :

install.packages("dtmapi")

Load Package

After installation, load the package using library():

library(dtmapi)

Get All Countries

The get_all_countries() function retrieves a list of all countries from the DTM API.

# Fetch all countries
countries_df <- get_all_countries()

# Display the first few rows of the data frame
head(countries_df)
#>                         admin0Name admin0Pcode
