Arguments

countryIds

Specify a comma separated list of country ids to filter by. For a list of countries use dhs_countries(returnFields=c("CountryName","DHS_CountryCode"))

indicatorIds

Specify a comma separated list of indicators ids to filter by. For a list of indicators use dhs_indicators(returnFields=c("IndicatorId","Label","Definition"))

selectSurveys

Specify to filter data from the latest survey by including 'selectSurveys=TRUE' in your request. Note: Please use this parameter in conjunction with countryCode, surveyType, or indicatorIds for best results.

surveyIds

Specify a comma separated list of survey ids to filter by. For a list of surveys use dhs_surveys(returnFields=c("SurveyId","SurveyYearLabel", "SurveyType","CountryName"))

surveyYear

Specify a comma separated list of survey years to filter by.

surveyYearStart

Specify a range of Survey Years to filter Surveys on. surveyYearStart is an inclusive value. Can be used alone or in conjunction with surveyYearEnd.

surveyYearEnd

Specify a range of Survey Years to filter Surveys on. surveyYearEnd is an inclusive value. Can be used alone or in conjunction with surveyYearStart.

surveyType

Specify a survey type to filter by.

surveyStatus

Every survey is assigned a surveys status and can be queried based on the surveyStatus parameter. 'surveyStatus="available"' (default) provides a list of all surveys for which the DHS API contains Indicator Data. 'surveyStatus="Completed"' provides a list of all completed surveys. NOTE: Data may not be available for every completed survey. 'surveyStatus="Ongoing"' provides a list of all ongoing surveys. 'surveyStatus="all"' provides a list of all surveys.

surveyCharacteristicIds

Specify a survey characteristic id to filter surveys with the specified survey characteristic. For a list of survey characteristics use dhs_surveys(returnFields=c("SurveyId", "SurveyYearLabel","SurveyType","CountryName"))

tagIds

Specify a tag id to filter surveys containing indicators with the specified tag. For a list of tags use dhs_tags()

f

You can specify the format of the data returned from the query as HTML, JSON, PJSON, geoJSON, JSONP, XML or CSV. The default data format is JSON.

returnFields

Specify a list of attributes to be returned.

perPage

Specify the number of results to be returned per page. By default the API will return 100 results.

page

Allows specifying a page number to obtain for the API request. By default the API will return page 1.

client

If the API request should be cached, then provide a client object created by client_dhs

force

Should we force fetching the API results, and ignore any cached results we have. Default = FALSE

all_results

Boolean for if all results should be returned. If FALSE then the specified page only will be returned. Default = TRUE.

Examples


## Not run: 
# A common use for the surveys API endpoint is to query which countries
# have conducted surveys since a given year, e.g. since 2010

dat <- dhs_surveys(surveyYearStart="2010")

# Additionally, some countries conduct non DHS surveys, but the data for
# thse is also available within the DHS website/API. To query these:

dat <- dhs_surveys(surveyType="MIS")

# Lastly, you may be interested to know about anything peculiar about a
# particular survey's implementation. This can be found by looking within
# the footnotes variable within the data frame returned. For example, the
# Madagascar 2013 MIS:

dat$Footnotes[dat$SurveyId == "MD2013MIS"]

# A complete list of examples for how each argument to the surveys 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-surveys.cfm
