As the year is drawing to a close, I'd would like to take the time to look back at the moments that were most important, fun, relevant, ... to the R community. In today's blog post, I will do this by chronologically listing...

Determine relationship between census geographic entities with totalcensus package

This is an application example of totalcensus package. The geographic hierarchy primer in Census 2010 summary file 1 technical documentation displays the relationship between geographic entities. The lower one of the two entities connected by a line is entirely within the boundary of the upper one. For example, a county subdivision is always within the boundaries of a county and...

Visualising US Voting Records with shinydashboard

Introducing adavis My second ever post on this blog was on introducing adamap, a Shiny app that maps Americans for Democratic Action voting scores (the so-called Liberal Quotient) between 1947-2015. It was built with highcharter, and hence it was nicely interactive but quite slow. I wanted to switch to another package since, and when I eventually ran into statebins, I...

This Stackoverflow question made me think about how to build formulae. For example, you might want to programmatically build linear model formulae and then map these models on data. For example, suppose the following (output suppressed): data(mtcars) lm(mpg ~ hp, data = mtcars) lm(mpg ~I(hp^2), data = mtcars) lm(mpg ~I(hp^3), data = mtcars) lm(mpg ~I(hp^4), data = mtcars) lm(mpg ~I(hp^5), data = mtcars) lm(mpg ~I(hp^6), data...

random wake

Just too often on X validated, one sees questions displaying a complete ignorance of the basics that makes one purposelessly wonder what is the point of trying to implement advanced methods when missing the necessary background. And just as often, I reacted to the question by wondering out loud about this… In the current case,

Sub-Gaussian property for the Beta distribution (part 3, final)

In this third and last post about the?Sub-Gaussian property for the Beta distribution (post 1 and post 2), I would like to show the interplay with the Bernoulli distribution as well as some connexions with optimal transport (OT is a hot topic in general, and also on this blog with Pierre’s posts on Wasserstein
