{manydata} is a portal to ‘many’ packages containing many datacubes, each containing many related datasets on many issue-domains, actors and institutions of global governance. These ‘many’ packages are: - {manyenviron}: contains data on international environmental agreements - {manytrade}: contains data on international trade agreements - {manyhealth}: contains data on international health agreements - {manystates}: contains data on states throughout history
Datasets are related to one another within a datacube through a particular coding system which follows the same principles across the different packages.
For instance, in the data packages on international agreements (including {manyenviron}, {manytrade}, and {manyhealth}), the agreements and memberships datacubes have standardised IDs (manyID), and date variables such as Begin and End that denote the beginning and end dates of treaties respectively. The beginning date is derived from the signature or entry into force date, whichever is the earliest available date for the treaty. Standardised IDs across datasets allow the same observations to be matched across datasets so that the values can be compared or expanded where relevant. These specific variable names allows the comparison of information across datasets that have different sources. It enables users to point out the recurrence, difference or absence of observations between the datasets and extract more robust data when researching on a particular governance domain.
The memberships datacube contains additional date variables on each state member’s ratification, signature, entry into force, and end dates for each treaty. Data in the memberships datacube is comparable across datasets through standardised state names and stateIDs, made possible with the manypkgs::code_states() function. More information on each state, including its Begin and End date, can be found in the {manystates} package.
To enable users to work with the data in these packages, {manydata} contains tools for:
We intend for {manydata} to be useful:
The easiest way to install {manydata} is directly from CRAN.
The development version of the package {manydata} can also be downloaded from GitHub.
Once {manydata} is installed, the call_ functions can be used to discover the ‘many packages’ currently available and/or download or update these packages when needed. For this, the call_packages() can be used.
library(manydata)
call_packages() # lists all packages currently available
call_packages("manytrade") # downloads and installs this packageThe call_sources() function obtains information about the sources and original locations of the desired datasets.

One major advantage of storing datasets in datacubes is that it facilitates the comparison and analysis of multiple datasets in a specific domain of global governance. To aid in the selection of datasets and the use of data within datacubes, the compare_ functions in {manydata} allows users to quickly compare different information on datacubes and/or datasets across ‘many packages’. These include comparison for data observations, variables, and ranges, overlap among observations, missing observations, and conflicts among observations.
For now, let’s work with the Roman Emperors datacube included in manydata. We can get a quick summary of the datasets included in this package with the following command:
We can see that there are three named datasets relating to emperors here: wikipedia (dataset assembled from Wikipedia pages), UNVR (United Nations of Roman Vitrix), and britannica (Britannica Encyclopedia List of Roman Emperors). Each of these datasets has their advantages and so we may wish to understand their similarities and differences, summarise variables across them, and perhaps also rerun models across them.
The compare_dimensions() function returns a tibble with the observations and variables of each dataset within the specified datacube of a many package.

The compare_missing() function returns a tibble with the number and percentage of missing observations in datasets within datacube.
Finally, the compare_categories() function help researchers identify how variables across datasets within a datacube relate to one another in five categories. Observations are matched by an “ID” variable to facilitate comparison. The categories here include ‘confirmed’, ‘majority’, ‘unique’, ‘missing’, and ‘conflict’. Observations are ‘confirmed’ if all non-NA values are the same across all datasets, and ‘majority’ if the non-NA values are the same across most datasets. ‘Unique’ observations are present in only one dataset and ‘missing’ observations indicate there are no non-NA values across all datasets for that variable. Observations are in ‘conflict’ if datasets have different non-NA values.
#> There were 116 matched observations by ID variable across datasets in datacube.
To retrieve an individual dataset from this datacube, we can use the pluck() function.
However, the real value of the various ‘many packages’ is that multiple datasets relating to the same phenomenon are presented together. {manydata} contains flexible methods for consolidating the different datasets in a datacube into a single dataset. For example, you could have the rows (observations) from one dataset, but add on some columns (variables) from another dataset. Where there are conflicts in the values across the different datasets, there are several ways that these may be resolved.
The consolidate() function facilitates consolidating a set of datasets, or a datacube, from a ‘many’ package into a single dataset with some combination of the rows and columns. The function includes separate arguments for rows and columns, as well as for how to resolve conflicts in observations across datasets. The key argument indicates the column to collapse datasets by. This provides users with considerable flexibility in how they combine data.
For example, users may wish to see units and variables coded in “any” dataset (i.e. units or variables present in at least one of the datasets in the datacube) or units and variables coded in “every” dataset (i.e. units or variables present in all of the datasets in the datacube).
