I’ve been thinking a bit on “competition” in the R ecosystem. I guess the closest I can come to a fair and coherent view on “competition” in the R...
A FOR loop is the most intuitive way to apply an operation to a series by looping through each item one by one, which makes perfect sense logically but...
Our R package wrapr supplies a "piping operator" that we feel is a real improvement in R code piped-style coding. The idea is: with wrapr‘s "dot arrow" pipe "%.__%"...
Introduction We all know that feeling. We have this great idea about a new project, feature, function, piece of code. What do we want? Write that amazing new code! When...
President Trump is once again causing distress by downplaying the number of deaths caused by Hurricane Maria's devastation of Puerto Rico last year. Official estimates initially put the death...
