Dean Burnett writes a column in Guardian, sometimes about science but more entertainingly on pseudo-, wannabe-, and not-actually- science. Most of the time this is good BS-shovelling fun and I recommend it. Unfortunately today we get some ill-considered overreach under the guise of shovelling. The subject is a silly equation purporting to define how depressing any day of the year is, and thereby to identify the most depressing one. It is sufficiently silly that it […]
R’s formula interface is sweet but sometimes confusing. ANOVA is seldom sweet and almost always confusing. And random (a.k.a. mixed) versus fixed effects decisions seem to hurt peoples’ heads too. So, let’s dive into the intersection of these three.
A little while ago I got a query about the calculation of the logit policy scales from Lowe et al. (2011).

Anyway, here’s the question: In the article you give the formula as . I had assumed that in the formula that ‘R’ and ‘L’ were the total […]
You have an SQLite database, perhaps as part of some replication materials, and you want to query it from R. You might want to be able to say: results < - runsql("select * from mytable order by date") and get the results back as an R object. Here's a function to do it.
Perhaps you are trying to add your nice new object as data for an R package. But wait. It has [gasp] foreign letters in its dimnames, so ‘R CMD check’ will certainly complain. What you need is something to turn R’s natural Unicode-processing goodness into a relic from the early days of computing without inadvertently aliasing any words that differ only by non-ASCII element. Here’s a handy iconv-invoking function to do that…
A couple of months ago somebody asked how to convert a new dictionary file so that it would run in the Yoshikoder. The format of the original file had two parts: the first half looked like: % 1 funct 2 pronoun 3 ppron 4 i 5 we ... which assigns identifiers to category labels, and a second half that looked like: % a 1 10 abandon* 125 127 130 131 137 abdomen* 146 147 abilit* […]
Perhaps you have a file written in Markdown with embedded R of the kind that RStudio makes so nice and easy but you’d like a range of output formats to keep your collaborators happy. Say latex, pdf, html and MS Word. Here’s what you might do
Here’s some steps that work for me on WordPress (v3.5)
