An important place in the history of statistics is AT&T Bell Laboratories. And one of the key parts of that story is the development of a language for statistical computing called S.Prior to 1975 or so, statistical researchers at Bell Labs used For...

If you need only a few truly random numbers you might use dice or atmospheric noise. However, if you need many random numbers you will have to use a pseudo random number generator (RNG). R includes support for different RNGs (c.f. ?Random) and a wide variety of distributions (c....

One of the functions I use the most is strsplit. It is quite useful if you want to separate a string by a specific character. Even if you have some complex rule for the split, most of the time you can solve this with a regular expression. However, recently I ...

This is a story (mostly) about how I started contributing to the rOpenSci package monkeylearn. I can’t promise any life flipturning upside down, but there will be a small discussion about git best practices which is almost as good 🤓. The tl;dr here is nothing novel but is ...

I recently saw a Reddit thread in r/PoliticalDiscussion asking the question “If the economy is still booming 2020, how should the Democratic address this?” This gets to an issue that’s been on my mind since at least 2016, maybe even 2014: when will the current period of economic growth end? For ...

Q is for qplotYou may have noticed that I frequently use the ggplot2 package and the ggplot function to produce graphics for my posts. ggplot2, which is part of the so-called tidyverse, is called gg to refer to the "grammar of graphics". That is, it uses standard functions and arguments ...

I read about Antonio Sánchez Chinchón’s clever approach to use the Travelling Salesperson algorithm to generate some math-art in R. The follow up was even nicer in my opinion, Pencil Scribbles. The subject was Boris Karloff as the monster in Frankenstein. I was interested in running the ...

I don’t know whether ‘rename taxa’ is a common task or not. It seems not a good idea to rename taxa in Newick tree text, since it may introduce problems when mapping the original sequence alignment to the tree. If you just want to show different or additional information ...
