Built-in datasets
Package "sdam" comes with a suite of datasets and external data to execute different functions available in the package and to perform analysis.
For a list of built-in datasets in "sdam" use the "utils" function data() or utils::data() with the 'package' argument.
The CRAN distribution has four built-in datasets, while the development and legacy distributions add three more built-in datasets.
# Data sets in package 'sdam':
#
# rp Roman province names and acronyms as in EDH
# rpcp Roman provinces chronological periods
# rpd Roman provinces dates from EDH
# rpmcd Caption maps and affiliation dates of Roman provinces# Additional built-in datasets in 'sdam':
#
# EDH Epigraphic Database Heidelberg Dataset
# rpmp Maps of ancient Roman provinces and Italian regions
# retn Roman Empire transport network and Mediterranean seaA description of each dataset is available in the manual that from the R console is accessible as e.g. the EDH dataset in a non-CRAN distribution.
Ancient Mediterranean built-in datasets
The EDH dataset in "sdam" has information about Latin epigraphy retrieved from the Epigraphic Database Heidelberg API repository from the Roman world during the antiquity period.
A list of Roman provinces and regions in this dataset is available in dataset "rp", and use again function data() to load this built-in dataset to look at its internal structure with utils::str() function.
- Dataset
"rp"is a named list with Roman provinces and regions with acronyms according to the Epigraphic Database Heidelberg.

- Function
edhw()is a wrapper to extract and transform the records in theEDHdataset that invokes"rp"dataset to retrieve the records from a specific Roman province or region inEDH.
Warning in edhw(province = "Arm"): "x" is for dataset "EDH".Warning in edhw(province = "Arm"): "province" with no "vars" returns lists.[[1]]

EDH in data frames
All records in the EDH dataset have a list format and it is possible to transform this information into a dataframe format with the wrapper function edhw(). For instance, displaying the first record from Arm as a data frame in argument 'as' is made by the record 'id' number.
However, it is easier to visualise in the screen only the variables related to people.
id cognomen gender name person_id
1 HD015521 Nerva+ Traianus male div[i] Nervae f[il. N]erva Traianus 1# record HD015521 with more explicit variables
edhw(id="15521", vars=c("people", "province_label"), as="df") id cognomen gender name person_id province_label
1 HD015521 Nerva+ Traianus male div[i] Nervae f[il. N]erva Traianus 1 ArmeniaObtaining all people variables
Start by looking at the people variables in the EDH dataset for the Roman province of Armenia.
Armenia
Roman province of Armenia (ca 117 AD).
Transformation of the entire province from the EDH dataset requires extracting first a list with the province content. Function edhw() is to obtain available inscriptions per province from EDH and all data attributes from people variable. The default outputs are a list and a dataframe for the first and the second instance of the function.
id age: years cognomen gender name
1 HD015521 <NA> Nerva+ Traianus male div[i] Nervae f[il. N]erva Traianus
2 HD015524 data not available Cre(---) male C. Val. Cre.
3 HD015524 <NA> [---] male [---]
nomen person_id praenomen status
1 <NA> 1 <NA> <NA>
2 Valerius* 1 C. military personnel
3 [---] 2 [-] military personnelPeople attribute variables in inscriptions for Armenia are age: years, cognomen, gender, name, nomen, person_id, praenomen, and, status, but any inscription with tribus or origo as in the case of other provinces.
For Armenia, two inscriptions have people variables and all people scripted are male, where record HD015524 spans two rows because there are two persons where one have nomen, cognomen, and name ineligible.
Datasets for cartographical maps
The plotting of the Roman province in the previous section requires other datasets. Apart from "rp". In "sdam", there are other three datasets invoked for plotting cartographical maps related to the Roman Empire and the Mediterranean basin, which are "rpmp", "rpmcd", and "retn".
Function plot.map() calls dataset "rpmp" for the shapes and colours in the plotting of the cartographical maps of different regions of the Roman Empire. For the caption and province dates with this function shapes and colours are in dataset "rpmcd".
- Dataset
"retn"bears the shapes of places and routes of an ancient transportation system in the Mediterranean region and political divisions of the Roman Empire. It also has it contours and parts of the European continent.
Vignette Cartographical maps and networks has more about transportation networks in the ancient Mediterranean.
Datasets with dates
There are built-in datasets in "sdam" related to dates as well that are either displayed in a cartographical map or used for other computations.
- Dataset
"rpd"that has dates for provinces from theEDHdataset. It serves for performing a restricted imputation on data subsets inEDHor in another dataset.

"rpcp"with chronological periods for regions with early and later Roman influence per province.
