EIA data

Source: R/data.R
eia_data.Rd

Obtain data from the EIA.

Usage

eia_data(
  dir,
  data = NULL,
  facets = NULL,
  freq = NULL,
  start = NULL,
  end = NULL,
  sort = NULL,
  length = NULL,
  offset = NULL,
  tidy = TRUE,
  check_metadata = FALSE,
  cache = TRUE,
  key = eia_get_key()
)

Arguments

dir

character, directory path.

data

character or NULL,

  • note: if NULL, eia_data() will only return column headings; must input a character value as provided by eia_metadata() for data to be returned.

  • see details.

facets

character list or NULL, see details.

freq

character or NULL, see details.

start, end

character or NULL, see details.

sort

named list of two.

  • cols: list column names on which to sort.

  • order: "asc" or "desc" for ascending or descending, respectively.

length

numeric or NULL, number of rows to return.

offset

numeric or NULL, number of rows to skip before return.

tidy

logical or NULL, return a tidier result. See details.

check_metadata

logical, if TRUE checks input values against metadata endpoint.

cache

logical, cache result for duration of R session using memoization. See details.

key

API key: character if set explicitly; not needed if key is set globally. See eia_set_key().

Value

data frame

Details

By default, data, facets, and freq are set to NULL. To obtain valid input values for each of these arguments, use the specific ID labels as provided by eia_metadata().

The use of start and end require some input to freq. By default (check_metadata = FALSE), the resulting data will match the temporal resolution provided to freq, however, check_metadata = TRUE applies further restrictions such that the format of values provided to start/end must match that of freq. Furthermore, regardless of the input format provided to start/end, the resulting data will always match the specification of freq. And lastly, regardless of chosen format, end must be strictly greater than start to return data.

By default, additional processing is done to return a list containing tibble data frames. Set tidy = FALSE to return only the initial list result of jsonlite::fromJSON. Set tidy = NA to return the original JSON as a character string.

Set to cache = FALSE to force a new API call for updated data. Using FALSE always makes a new API call and returns the result from the server. TRUE uses memoization on a per R session basis, caching the result of the function call in memory for the duration of the R session. You can reset the entire cache by calling eia_clear_cache().

Examples

if (FALSE) {
eia_data(
  dir = "electricity/retail-sales",
  data = "price",
  facets = list(sectorid = c("COM", "RES"), stateid = "OH")
)
}
