Examples

## Not run: 
# A common use for the countries API endpoint is to query which countries
# ask questions about a given topic. For example to find all countries that
# record data on malaria prevalence by RDT:

dat <- dhs_countries(indicatorIds = "ML_PMAL_C_RDT")

# Additionally you may want to know all the countries that have conducted
# MIS (malaria indicator surveys):

dat <- dhs_countries(surveyType="MIS")

# A complete list of examples for how each argument to the countries API
# endpoint can be provided is given below, which is a copy of each of
# the examples listed in the API at:

# https://api.dhsprogram.com/#/api-countries.cfm
