Get possible data types for a particular dataset

Source: R/ncdc_datatypes.r
ncdc_datatypes.Rd

From the NOAA API docs: Describes the type of data, acts as a label. For example: If it's 64 degrees out right now, then the data type is Air Temperature and the data is 64.

Usage

ncdc_datatypes(
  datasetid = NULL,
  datatypeid = NULL,
  datacategoryid = NULL,
  stationid = NULL,
  locationid = NULL,
  startdate = NULL,
  enddate = NULL,
  sortfield = NULL,
  sortorder = NULL,
  limit = 25,
  offset = NULL,
  token = NULL,
  ...
)

Arguments

datasetid

(optional) Accepts a valid dataset id or a vector or list of them. Data returned will be from the dataset specified.

datatypeid

Accepts a valid data type id or a vector or list of data type ids. (optional)

datacategoryid

Optional. Accepts a valid data category id or a vector or list of data category ids (although it is rare to have a data type with more than one data category)

stationid

Accepts a valid station id or a vector or list of station ids

locationid

Accepts a valid location id or a vector or list of location ids (optional)

startdate

(optional) Accepts valid ISO formated date (yyyy-mm-dd) or date time (YYYY-MM-DDThh:mm:ss). Data returned will have data after the specified date. The date range must be less than 1 year.

enddate

(optional) Accepts valid ISO formated date (yyyy-mm-dd) or date time (YYYY-MM-DDThh:mm:ss). Data returned will have data before the specified date. The date range must be less than 1 year.

sortfield

The field to sort results by. Supports id, name, mindate, maxdate, and datacoverage fields (optional)

sortorder

Which order to sort by, asc or desc. Defaults to asc (optional)

limit

Defaults to 25, limits the number of results in the response. Maximum is 1000 (optional)

offset

Defaults to 0, used to offset the resultlist (optional)

token

This must be a valid token token supplied to you by NCDC's Climate Data Online access token generator. (required) See Authentication section below for more details.

...

Curl options passed on to HttpClient (optional)

Value

A data.frame for all datasets, or a list of length two, each with a data.frame

Authentication

Get an API key (aka, token) at https://www.ncdc.noaa.gov/cdo-web/token You can pass your token in as an argument or store it one of two places:

  • your .Rprofile file with the entry options(noaakey = "your-noaa-token")

  • your .Renviron file with the entry NOAA_KEY=your-noaa-token

See Startup for information on how to create/find your .Rrofile and .Renviron files
