This reproducible R Markdown analysis was created with workflowr (version 1.7.0). The Checks tab describes the reproducibility checks that were applied when the results were created. The Past versions tab lists the development history.


Great! Since the R Markdown file has been committed to the Git repository, you know the exact version of the code that produced these results.

Great job! The global environment was empty. Objects defined in the global environment can affect the analysis in your R Markdown file in unknown ways. For reproduciblity it’s best to always run the code in an empty environment.

The command set.seed(20230302) was run prior to running the code in the R Markdown file. Setting a seed ensures that any results that rely on randomness, e.g. subsampling or permutations, are reproducible.

Great job! Recording the operating system, R version, and package versions is critical for reproducibility.

Nice! There were no cached chunks for this analysis, so you can be confident that you successfully produced the results during this run.

Great job! Using relative paths to the files within your workflowr project makes it easier to run your code on other machines.

Great! You are using Git for version control. Tracking code development and connecting the code version to the results is critical for reproducibility.

The results in this page were generated with repository version 5ef241f. See the Past versions tab to see a history of the changes made to the R Markdown and HTML files.

Note that you need to be careful to ensure that all relevant files for the analysis have been committed to Git prior to generating the results (you can use wflow_publish or wflow_git_commit). workflowr only checks the R Markdown file, but you know if there are other scripts or data files that it depends on. Below is the status of the Git repository when the results were generated:


Ignored files:
    Ignored:    .DS_Store
    Ignored:    .Rhistory
    Ignored:    .Rproj.user/
    Ignored:    data/.DS_Store

Note that any generated files, e.g. HTML, png, CSS, etc., are not included in this status report because it is ok for generated content to have uncommitted changes.


These are the previous versions of the repository in which changes were made to the R Markdown (analysis/demo-data.Rmd) and HTML (docs/demo-data.html) files. If you’ve configured a remote Git repository (see ?wflow_git_remote), click on the hyperlinks in the table below to view the files as they were in that past version.

Population size

The demographic data that the analyses will rely on for now is based on a combination of Hacker et al 2020, US Census and Graham Coop’s inputs for Edge & Coop 2019.

This GitHub Repo contains an .xls file with multiple sheets that contain the different inputs (here). Below is the final file that was uploaded and used in the analyses:

library(readr)
est_pop_combo <- read_csv("data/est-pop-combo.csv")
Rows: 39 Columns: 4

Database size

What are realistic database sizes for US European- and African American populations? From 23andMe publications it seems that 80% of their customers identify as White (non-Hispanic) and that around 3% of their customers identify as African American or Black (see here where they say that their sample represents their customer database and the US population). This broadly agrees with data seen in a 23andme poster presented in 2011 (see here)

For now, the analyses will use an estimate of 80% for White Americans and 5% for Black Americans in the DTC databases.

Detailed demographic data

The website here has some figures from an exploratory analysis of birth rate-related data from IPUMS. We will revisit this when we simulate populations and need to draw from this data for the parameters.
