AQS API QA Annual Performance Evaluations Transaction service

Description

A collection of functions to fetch pairs of data QA at several concentration levels in the submission (transaction) format for AQS.

Usage

aqs_transactionsqaannualperformanceevaluations(
  aqs_filter = c("bySite", "byCounty", "byState", "byPQAO", "byMA"),
  aqs_variables = NULL,
  header = FALSE,
  ...
)

transactionsqaannualperformanceevaluations_bysite(
  param,
  bdate,
  edate,
  state,
  county,
  site,
  email = get_aqs_email(),
  key = get_aqs_key(),
  header = FALSE,
  ...
)

transactionsqaannualperformanceevaluations_bycounty(
  param,
  bdate,
  edate,
  state,
  county,
  email = get_aqs_email(),
  key = get_aqs_key(),
  header = FALSE,
  ...
)

transactionsqaannualperformanceevaluations_bystate(
  param,
  bdate,
  edate,
  state,
  email = get_aqs_email(),
  key = get_aqs_key(),
  header = FALSE,
  ...
)

transactionsqaannualperformanceevaluations_bypqao(
  param,
  bdate,
  edate,
  pqao,
  email = get_aqs_email(),
  key = get_aqs_key(),
  header = FALSE,
  ...
)

transactionsqaannualperformanceevaluations_byma(
  param,
  bdate,
  edate,
  agency,
  email = get_aqs_email(),
  key = get_aqs_key(),
  header = FALSE,
  ...
)

Arguments

aqs_filter

A string specifying one of the service filters. NOT case-sensitive.

aqs_variables

A named list of variables to fetch data (e.g., state). Only necessary variables are passed to a specific endpoint (service/filter) to make a valid request.

header

A logical specifying whether the function returns additional information from the API header. Default is FALSE to return data only.

...

Reserved for future use.

param

A string or vector of strings specifying the 5-digit AQS parameter code for data selection. An integer will be coerced to a string. A maximum of 5 parameter codes may be listed in a single request. A list of the parameter codes can be obtained via list_parametersbyclass.

bdate

A string specifying the begin date of data selection in YYYYMMDD format. Only data on or after this date will be returned.

edate

A string specifying the end date of data selection in YYYYMMDD format. Only data on or before this date will be returned. If the end date is not in the same year as the begin date, the function will automatically split the date range into multiple chunks by year and send requests sequentially.

state

A string specifying the 2-digit state FIPS code. An integer will be coerced to a string with a leading zero if necessary (e.g., 1 -> "01"). A list of the state codes can be obtained via list_states.

county

A string specifying the 3-digit county FIPS code. An integer will be coerced to a string with leading zeros if necessary (e.g., 89 -> "089"). A list of the county codes within each state can be obtained via list_countiesbystate.

site

A string specifying the 4-digit AQS site number within the county. An integer will be coerced to a string with leading zeros if necessary (e.g., 14 -> "0014"). A list of the site codes within each county can be obtained via list_sitesbycounty.

email

A string specifying the email address of the requester. If you set your email and key with set_aqs_user, you don't have to specify this.

key

A string specifying the key matching the email address for the requester. If you set your email and key with set_aqs_user, you don't have to specify this.

pqao

A string specifying the AQS Primary Quality Assurance Organization (PQAO) code. A list of the PQAO codes can be obtained via list_pqaos.

agency

A string specifying the AQS Monitoring Agency (MA) code. A list of the MA codes can be obtained via list_mas. Here, we named this input as agency instead of "ma" because agency is actually used in the API endpoint URL.

Details

aqs_transactionsqaannualperformanceevaluations sends a request to the AQS API based on a user-provided filter using the following underlying functions:

Value

A data.frame containing parsed data or a named list containing header and data.

Examples

## Not run: 

## Set your API Key first using set_aqs_user to run the following codes

## Example from the AQS website
## Annual performance evaluation data for ozone in Alabama during 2017
aqs_variables <- list(
  param = "44201", bdate = "20170101", edate = "20171231",
  state = "01"
)
aqs_transactionsqaannualperformanceevaluations(
  aqs_filter = "byState", aqs_variables = aqs_variables
)

## Equivalent to above; used integers instead of strings
transactionsqaannualperformanceevaluations_bystate(
  param = 44201, bdate = "20170101", edate = "20171231",
  state = 1
)

## End(Not run)
