Completely unrelated concept: unit testing is part of a regression testing framework while OFAT is a (almost always suboptimal) test strategy for designed experiments. See: https://en.m.wikipedia.org/wiki/One-factor-at-

The helium used to fill balloons is no different than the helium used to cool MRIs. The latter has just been liquified.

Several of the maps were made by Twitter users @researchremora and @cstats1, using R and the rayshader package.

I'm always really impressed with the clever techniques and methods to accurately map topographic surfaces (in this case, lunar) before computerization. Really interesting! (and your comment reminded me to finally place my order for a K

Opensubdiv would definitely be the robust, industry standard solution. However, R packages that are distributed on the CRAN have additional restrictions on required system libraries, so for portability I went with a bespoke implementation.

My personal favorite resource is "R for Data Science" by Hadley Wickham. It covers lots of nice data manipulation and visualization examples, and provides a good introduction to the tidyverse, which is a particular dialect of R th

I have not. I started using R due to its open source codebase and ability to audit and understand exactly what its doing under the hood—being able to see how statistical formulae were implemented in code was invaluable in understanding and

I remapped the UV coords based on the spherical projection of the mesh after subdividing, so there should be minimal distortion, especially compared the UV sphere. There is a slightly higher density of vertices where the edges of the cube u

R is hands-down the best language for data manipulation, analysis, and visualization: it's a language truly centered around treating data as a first class citizen. That focus does make some traditional programming workflows more error

Thanks for the kind words! You can also see the documentation/examples for {rayrender}, the pathtracer I wrote for R, here: https://www.rayrender.net And the rasterizer/mesh manipulation package {rayvertex} here: http

I believe they are using the percentages as part of the height of the bar chart! I thought I'd seen every way someone could do dataviz wrong (particularly with a bar chart), but this one is new to me.

The word you’re looking for is “cheaper,” not “accessible.” Those 1x1m elevators certainly aren’t accessible for wheelchair users. ADA requirements require the following minimum dimensions for an elevator: “The width of the elevator car is

Agreed--the R base pipe and right assignment operator obviate the need for a pipe assignment operator.

R’s data visualization capabilities are heads and shoulders above Matlab’s, and it’s free and open source.
