Retrieve Star Trek data from STAPI

Description

Retrieve Star Trek data from the Star Trek API (STAPI).

Usage

stapi(id, page = 1, uid = NULL, page_count = FALSE)

Arguments

`id`	character, name of STAPI entity. See details.
`page`	integer vector, defaults to first page.
`uid`	`NULL` for search mode, character for extraction mode. See details.
`page_count`	logical, set to `TRUE` to do a preliminary check of the total number a pages of results available for a potential entity search. This will only have the impact of searching the first page.

Details

See stapiEntities() for all the currently available API entities. These are the IDs for dataset collections or categories passed to id.

The universal ID uid can be supplied to retrieve a more specific subset of data. By default, uid = NULL and stapi() operates in search mode. As part of a stepwise process, you can first use search mode. Then if the resulting data frame includes a uid column, you can make a second call to the function providing a specific uid. This puts stapi() into extraction mode and will return satellite data associated with the unique entry from the original general sweep of the entity id.

rtrek employs anti-DOS measures. It will not perform an API call to STAPI more than once per second. To be an even better neighbor, you can increase this wait time using options(), e.g. options(rtrek_antidos = 10) to increase the minimum time between API calls to ten seconds. Values less than one are ignored (defaulting back to one second) and a warning will be thrown when making any API call if this is the case.

Currently STAPI contains primarily real world data such as episode air dates, movie metadata, or production company information. Fictional world data is secondary and more limited.

Value

a data frame in search mode, a list in extraction mode, and nothing is returned in page count check mode but the result is printed to the console.

Examples


library(dplyr)
stapi("character", page_count = TRUE) # check first
stapi("character", page = 2) |> select(1:2)
Q <- stapi("character", uid = "CHMA0000025118")
Q$episodes |> select(uid, title, stardateFrom, stardateTo)
