Quickstart

Obtain an API key in your dashboard and initialize the client:

library(altadata)
aldatata.api_key('YOUR_API_KEY')

Retrieving Data

You can get the entire data with the code below.

altadata.get_data(product_code = 'PRODUCT_CODE')
data <- altadata.load()

Retrieving Subscription Info

You can get your subscription info with the code below.

subscription_info <- altadata.list_subscription()

Retrieving Data Header Info

You can get your data header with the code below.

header_info <- altadata.get_header(product_code = 'PRODUCT_CODE')

Retrieving Data with Conditions

You can get data with using various conditions.

The columns you can apply these filter operations to are limited to the filtered columns.

You can find the filtered columns in the data section of the data product page.

equal condition

PRODUCT_CODE <- 'co_10_jhucs_03'
altadata.get_data(product_code = PRODUCT_CODE)
altadata.equal(condition_column = "province_state", condition_value = "Alabama")
data <- altadata.load()

in condition

PRODUCT_CODE <- 'co_10_jhucs_03'
altadata.get_data(product_code = PRODUCT_CODE)
altadata.condition_in(condition_column = "province_state", condition_value = c("Utah", "Alabama"))
data <- altadata.load()

condition_value parameter of condition_in method must be Array

not in condition

PRODUCT_CODE <- 'co_10_jhucs_03'
altadata.get_data(product_code = PRODUCT_CODE)
altadata.condition_not_in(condition_column = "province_state", condition_value = c("Montana", "Utah", "Alabama"))
data <- altadata.load()

condition_value parameter of condition_not_in method must be Array

sort operation

PRODUCT_CODE <- 'co_10_jhucs_03'
altadata.get_data(product_code = PRODUCT_CODE)
altadata.sort(order_column = "reported_date", order_method = "asc")
data <- altadata.load()

Default value of order_method parameter is 'asc' and order_method parameter must be 'asc' or 'desc'

select specific columns

PRODUCT_CODE <- 'co_10_jhucs_03'
altadata.get_data(product_code = PRODUCT_CODE)
altadata.select(selected_columns = c("reported_date", "province_state", "population"))
data <- altadata.load()

selected_column parameter of select method must be Array

get the specified amount of data

PRODUCT_CODE <- 'co_10_jhucs_03'
altadata.get_data(product_code = PRODUCT_CODE, limit = 50)
data <- altadata.load()

Retrieving Data with Multiple Conditions

You can use multiple condition at same time.

PRODUCT_CODE <- 'co_10_jhucs_03'
altadata.get_data(product_code = PRODUCT_CODE)
altadata.condition_in(condition_column = "province_state", condition_value = c("Utah", "Alabama"))
altadata.select(selected_columns = c("reported_date", "province_state", "population"))
data <- altadata.load()
