Creating Colorblind-Friendly Figures

Color is often used to display an extra dimension in plots of scientific data. Unfortunately, everyone does not decode color in exactly the same way. This is especially true for those with color vision deficiency, which affects up to 8 percent of the population in its two most common forms. As a result, it has been estimated that the...

A Bayesian Model for a Function Increasing by Chi-Squared Jumps (in Stan)

(This article was first published on David Chudzicki's Blog, and kindly contributed to R-bloggers) This post will describe a way I came up with of fitting a function that’s constrained to be increasing, using Stan. If you want practical help, standard statistical approaches, or expert research, this isn’t the place for you (look up “isotonic regression” or “Bayesian isotonic...

By
shinyGL

The rgl package has been used to produce rich, interactive 3D graphics within R using the OpenGL framework for some time. The rgl authors also added the ability to export to WebGL, allowing R authors to produce interactive 3D graphics that were accessible from within any modern web browser. This functionality can now be leveraged

Remembering the Gist, But Not the Details:  One-Dimensional Representation of Consumer Ratings

In survey research, it makes a difference how the question is asked.  "How would you rate the service you received at that restaurant?" is not the same as "Did you have to wait to be seated, to order your meal, to be served your food, or to pay yo...

Custom Legend in R

This particular custom legend was designed with three purposes: To effectively bin values based on a theoretical minimum and maximum value for that variable (e.g. -1 and 1 or 0 and 100) To use a different interval notation than the default To handle NA values Even though this particular legend was designed with those needs, it should be simple to extrapolate from...

RegEx: Named Capture in R (Round 2)

October 9, 2013
By

Previously, I came up with a solution to R's less than ideal handling of named capture in regular expressions with my re.capture() function. A little more than a year later, the problem is rearing its ugly - albeit subtly different - head again. I now...
