This introductory vignette provides a brief, example-driven overview
of rtrek.
The rtrek package provides datasets related to the Star
Trek fictional universe and functions for working with those datasets.
It interfaces with the Star Trek API
(STAPI), Memory Alpha
and Memory
Beta to retrieve data, metadata and other information relating to
Star Trek.
The package also contains several local datasets covering a variety
of topics such as Star Trek timeline data, universe species data and
geopolitical data. Some of these are more information rich, while others
are toy examples useful for simple demonstrations. The bulk of Star Trek
data is accessed from external sources by API. A future version of
rtrek will also include summary datasets resulting from
text mining analyses of Star Trek novels.

included in the package in order to demonstrate some very basic examples
and they are not particularly useful or interesting beyond this purpose.
However, rtek now includes more sizable curated datasets
relating the compendium of licensed, published Star Trek literature and
multiple versions of Star Trek fictional universe historical
timelines.
Package datasets in rtrek are somewhat eclectic and
currently limited. They will expand with further package development. To
list all available package datasets with a short description, call
st_datasets.
A largely comprehensive Star Trek book metadata table is available as
stBooks, which is informed and curated from directly
parsing Star Trek e-book metadata rather than parsing third party
website content.

One thing to keep in mind is these tile sets use a simple/non-geographical coordinate reference system (CRS). Clearly, they are not Earth-based, though they are spatial in more ways than one!
Similar to game maps, there is a sense of space, but it is a simple Cartesian coordinate system and does not use geographic projections like you may be used to working with when analyzing spatial data or making Leaflet maps. This system is much simpler, but simple does not necessarily mean easy!

#> 18 galaxy2 Talar 1338 2368This is another small dataset containing locations of key planets in the Star Trek universe. Notice the coordinates do not appear meaningful. There is no latitude and longitude. Instead there are row and column entries defining cells in a matrix. The matrix dimensions are defined by the pixel dimensions of source map that was used to create each tile set.
The coordinates are also not consistent. Source maps differ significantly. Even if they had identical pixel dimensions, which they do not, each artist’s visual rendering of the fictional universe will place locations differently in space. In this sense, every tile set has a unique coordinate reference system. For each new tile set produced, all locations of interest must be georeferenced again.
This is not ideal, but it gets worse. Once you have locations’
coordinates defined that map onto a particular tile set, the
leaflet package does not work in these row and column
grids. The (col, row) pairs need to be transformed or
projected into Leaflet space. Fortunately, rtrek does this
part for you with tile_coords. It takes a data frame like
one returned by st_tiles_data with columns named
col and row, as well as the name of an
available Star Trek map tile set. It returns a data frame with new
columns x and y that will map properly in a
leaflet map built on that tile set.

leaflet. The st_tiles function is used to link
to the tile provider.
library(leaflet)
tiles <- st_tiles("galaxy1")
leaflet(d, options = leafletOptions(crs = leafletCRS("L.CRS.Simple"))) %>%
addTiles(tiles) %>% setView(108, -75, 2) %>%
addCircleMarkers(lng = ~x, lat = ~y, label = ~loc, color = "white", radius = 20)The stSpecies dataset is just a small table that pairs
species named with representative thumbnail avatars, mostly pulled from
the Memory Alpha website. There is nothing map-related here, but these
are used in this Stellar
Cartography example. It is similar to the Leaflet example above, but
a bit more interesting, with markers to click on and information
displays.
In the course of the above map-related examples, a few functions have
also been introduced. st_tiles takes an id
argument that is mapped to the available tile sets in
stTiles and returns the relevant URL.
st_tiles_data takes the same id argument and
returns a simple example data frame containing ancillary data related to
the available locations from stGeo. The result is always
the same except that the grid cells for locations change with respect to
the chosen tile set. Finally, tile_coords can be applied to
one of these data frames to add x and y
columns for a CRS that Leaflet will understand.
Fictional universe historical timeline data is an exciting type of in-universe Star Trek data to have at your fingertips to play around with and explore.
It is also difficult to compile. Many people have labored away intensely over the years compiling various attempts at integrated, internally consistent, accurate timelines of Star Trek universe lore. Some have turned out more successful than others.
As of rtrek v0.2.0 the rudimentary
beginnings of what will ideally eventually become an up to date and
comprehensive timeline dataset are now underway in the form of two
different flavors of timeline datasets.
One is based on published works, mostly consisting of novels, as well as television series and movies, all placed in chronological order.

One column these two timeline data frames share in common is the
footnote column, which you can see only contains ID values
for entries which have a footnote. The tlFootnotes dataset
can be referenced or joined by footnote to one of the other
tables. Footnotes tend to be long strings of text and not associated
with most timeline entries, so they are kept in a separate table.

#> # ℹ 595 more rowstlBooks is novel-driven, meaning that the timeline
entries (rows) provide a chronologically ordered list of licensed Star
Trek novels. This timeline is helpful for figuring out when stories are
set and the relative order in which they occur, but it does not provide
any description of events transpiring in the universe.
While this data is very informative, it is many years out of date, being last updated in October of 2006. It is also necessarily speculative. Settings are determined based in part on what is interpreted to be the intention of a given author for a given story.
Nevertheless, it still represents possibly the highest quality representation of the chronological ordering of Star Trek fiction that combines episodes and movies with written works. The concurrent timeline of Star Trek TV episodes and movies are interleaved with the novels and other stories, anthologies and other written fiction. This provides fuller context resulting in a much richer timeline.
tlEvents is event-driven, meaning that the timeline
entries (rows) provide chronologically ordered historical events from
the Star Trek universe. As with tlBooks, this timeline is
quite out of date. In fact it is at least somewhat more out of date than
tlBooks, its last content update appearing to be no later
than 2005. This timeline is also more problematic than the other, and
less relevant moving forward. Its updating essentially ceased as the
other began.
However, it is included because unlike tlBooks, which is
a timeline of production titles, this timeline dataset is event-driven.
While it may now be erroneous in places even independent from being out
of date, it is useful for its informative textual entries referencing
historically significant events in Star Trek lore.
In summary, these datasets have much value, but they should be used
with the awareness that they are necessarily imperfect ans speculative,
notably outdated, and tlEvents in particular is less able
to stand the test of time as the Star Trek universe moves forward with
new publications and productions.
It should also be noted that while it may be tempting to merge these two data frames, this is not advisable if it is important to maintain chronological order. It is generally safe to assume that multiple entries within a single year are listed in a sensible order in cases where it may matter, within-year entries do not have specific, unique within-year dates. They are ordinal only. It is not possible to merge entries from both tables for a specific year and know how the combined set of entries should be ordered- unless you already know everything about Star Trek, in which case please craft the ultimate timeline in a universal file format that can be easily digested by a computer.
Now that you have seen an overview of available rtrek
datasets and some associated functions, it is time to turn attention to
external datasets. The Star Trek API
(STAPI) is a particularly useful data source.
Keep in mind that STAPI focuses more on providing real world data associated with Star Trek (e.g., when did episode X first air on television?) than on fictional universe data, but it contains both and the database holdings will grow with time.
To use the words of the developers, the STAPI is
the first public Star Trek API, accessible via REST and SOAP. It’s an open source project, that anyone can contribute to.
The API is highly functional. Please do not abuse the API with
constant requests. Their pages suggest no more than one request per
second, but I would suggest ten seconds between successive requests. The
default anti-DOS measures in rtrek limit requests to one
per second. You can update this global rtrek setting with
options, e.g. options(rtrek_antidos = 10) for
a minimum ten second wait between API calls to be an even better
neighbor. rtrek will not permit faster requests. If set
below one second, the option is ignored and a warning thrown when making
any API call.
There a many fields, or entities, available in the API. The available IDs can be found in this table:
stapiEntities

#> 10 comicStrip tbl_df 12 <chr [12]>
#> # ℹ 30 more rowsThese ID values are passed to stapi to perform a search
using the API. The other columns provide some information about the
object returned from a search. All entity searches return tibble data
frames. You can inspect or unnest the column names of each table
returned from every available entity search so you can see beforehand
what variables are associated with each entity.
Using stapi should be thought of as a three part
process:
stapi one more time referencing the specific
observation.To determine how many pages of results exist for a given search, set
page_count = TRUE. The impact on the API will be equivalent
to only searching a single page of results. One page contains metadata
including the total number of pages. Nothing is returned in this “safe
mode”, but the total number of search results available is printed to
the console.
Searching movies only returns one page of results. However, there are a lot of characters in the Star Trek universe. Check the total pages available for character search.
stapi("character", page_count = TRUE)
#> Total pages to retrieve all results: 76And that is with 100 results per page!
The default page = 1 only returns the first page.
page can be a vector, e.g. page = 1:62.
Results from multi-page searches are automatically combined into a
single, constant data frame output. For the second call to
stapi, return only page two here, which contains the
character, Q (currently, pending future character database updates that
may shift the indexing). In case that does change and Q is not always
near the top of page two of the search results, the example further
below hard-codes his unique/universal ID.
stapi("character", page = 2)

Even for more popular characters about whom much more universe lore has been uncovered, it still takes dedicated nerds to enter all the data in a database.
When a dataset contains a uid column, this can be used
subsequently to extract a satellite dataset about that particular
observation that was returned in the original search. First you used
safe mode, then search mode, and now switch from search mode to
extraction mode to obtain data about Q, specifically. All that is
required to do this is pass Q’s uid to stapi
and call the function one last time. When uid is no longer
NULL, stapi knows not to bother with a search
and makes a different type of API call requesting information about the
uniquely identified entry.

Some functions in rtrek provide an API-like
interface to online Star Trek-related data. Specifically, parsing data
from the Memory Alpha
and Memory
Beta websites. These sites do not provide APIs. Therefore the only
option is to read pages into R and parse the html. Behind the scenes
this is done using the xml2 and rvest
packages, but from the user perspective it is presented as passing an
API endpoint string to a function.
memory_alpha and memory_beta, as well as
several other related functions, are available in rtrek.
These functions access data from Memory Alpha and Memory Beta. For
details and examples on these functions, see the Memory Alpha vignette
and the Memory Beta vignette.
This section will be continued in a future version of
rtrek. For now what is available is a dataset
stBooks. This dataset represents metadata parsed,
imperfectly but painstakingly and thoroughly, from actual Star Trek
books. stBooks contains several different fields, including
useful fields for analysts such as the number of words and chapters in a
book.
