Client for the 'FieldClimate' API.

rfieldclimate

An R client for Fieldclimate API

Installation

remotes::install_github("basf/rfieldclimate")

Examples

library("rfieldclimate")

Authentication

rfieldclimate uses HMAC for authentication.

The public and private keys are read by default from environmental variables FC_PUBLIC_KEY and FC_PRIVATE_KEY, but you can provide them also in every function call using the public_key= and private_key= arguments.

Basic use

fc_request() is the workhorse of this package.

With it you can query every API endpoint, e.g.

fc_request(method = "GET", path = "/system/types") %>%
  head(2)

See the Routes tables API documentation for details. URL parameters must be included in the path= arguments, the request body in body=.

Wrappers

With fc_request() all the api functionality can be easily covered. Additionally, we provide some wrappers around endpoints.

E.g. the wrapper for station information (see below) is defined as

fc_get_station
#> function(station_id = NULL, ...) {
#>   stopifnot(!is.null(station_id))
#>   path <- file.path('/station', station_id)
#>   fc_request(method = "GET", path = path, ...)
#> }
#> <bytecode: 0x55b67f00f260>
#> <environment: namespace:rfieldclimate>

For a few other endpoints wrapper functions are provided:

• fc_get_user() to list user information
• fc_get_user_stations() to list available stations
• fc_get_station() to get station information
• fc_get_data() to get data range of a station
• fc_get_data_range() to get data in range

Feel free to add more wrappers (as described above).

Parsers

We provide also convenience wrappers for objects, like

• fc_parse_data() to parse the object returned by fc_get_data_range() into a long format data.frame
• fc_parse_stations() to parse the object returned by fc_get_user_stations() into a data.frame

Unit tests

To run the full test suite with 100% coverage set valid environmental variables FC_PUBLIC_KEY and FC_PRIVATE_KEY and run devtools::test().
