crowdopt: Crowd-Optimized R Functions

In vandomed/crowdopt: Crowd-Optimized R Functions

Description

Faster versions of base R functions (e.g. weighted mean, standard deviation, covariance), mostly written in C++. Function names are the same as the corresponding base R functions, but with a 2 added (e.g. weighted.mean2 for weighted.mean).

Details

The concept for this package is crowdsourced optimization for speed. Long term, the goal is to optimize enough base R functions that a typical R user can drastically speed up their scripts by simply loading **crowdopt** and replacing functions with the optimized version.

Anyone can contribute on GitHub (https://github.com/vandomed/crowdopt). Once you contribute a function, you become a co-author for the package, and remain a co-author even if your function eventually gets replaced by a faster one developed by somebody else.

To contribute a function, all you need to do is add 1 .R file with the code and documentation for your function, using roxygen2 syntax. You can use range2.R as a template. Be sure to include an Examples section in which you demonstrate that your function is faster than the corresponding base R function.

In general, contributed functions should be substantially faster than the corresponding base R function, ideally for both small and large objects (e.g. vectors of length 5 and 500,000).
