Parameterized RMarkdown is Amazing

Parameterized R Markdown A while back, I learned that you can parameterize markdown. You can send it something to process as argument. This is amazing. Let me show an example.

GDPR Violations

R Markdown I love this intro photo from the tidyTuesday page. This week’s tidyTuesday data cover violations of the GDPR (General Data Protection Regulations) regulatory regime for data privacy in the European Union. The Wikipedia entry on GDPR is fairly extensive. The dataset is large and suggests some interesting regulatory arbitrage. Let’s have a look at the data. First, let’s load them. gdpr_violations <- readr::read_tsv('https://raw.githubusercontent.com/rfordatascience/tidytuesday/master/data/2020/2020-04-21/gdpr_violations.tsv') ## ## ── Column specification ──────────────────────────────────────────────────────── ## cols( ## id = col_double(), ## picture = col_character(), ## name = col_character(), ## price = col_double(), ## authority = col_character(), ## date = col_character(), ## controller = col_character(), ## article_violated = col_character(), ## type = col_character(), ## source = col_character(), ## summary = col_character() ## ) gdpr_text <- readr::read_tsv('https://raw.

New York Times Data on COVID

The New York Times has a wonderful compilation of United States on the novel coronavirus. The data are organized as a panel for US counties and have been continuously collected and updated since March of 2020. For US data, it is as authoritative a source as I am aware of and it provides a nice basis for visualizing various aspects of the pandemic. This commentary was originally provided in late March of 2020.

COVID in the US and the World

The Johns Hopkins dashboard This is what Johns Hopkins has provided as a dashboard using ARCGIS. They have essentially layered out the data into national and subnational data and then used the arcgis dashboard to cycle through them. The data There are a few different types of data available.
