Overview

About

Basic functions, implemented in C, for large data manipulation. Fast vectorised ifelse()/nested if()/switch() functions, psum()/pprod() functions equivalent to pmin()/pmax() plus others which are missing from base R. Most of these functions are callable at C level.

Changes in 0.0.21

New Features

  • Functions fpmin, fpmax, and prange are added as parallel equivalents of base R pmin, pmax, and range operations. These functions compute element-wise minimum, maximum, and range (max - min) across multiple vectors. They support integer, logical, and double types, with automatic type promotion. Implemented by @SebKrantz.

Notes

  • The GitHub repo move to fastverse/kit, a new website exists at fastverse.org/kit, and Sebastian Krantz and the *fastverse* Team have taken responsibility to maintain the package. Morgan Jacob has stepped down, but remains available for consultation.
