arrApply 2.1

Apply a Function to a Margin of an Array

Released Mar 8, 2019 by Serguei Sokol

This package can be loaded by Renjin but all tests failed. An older version of this package is more compatible with Renjin.

Dependencies

RcppArmadillo 0.9.200.7.1 Rcpp

High performance variant of apply() for a fixed set of functions. Considerable speedup is a trade-off for universality, user defined functions cannot be used with this package. However, 21 most currently employed functions are available for usage. They can be divided in three types: reducing functions (like mean(), sum() etc., giving a scalar when applied to a vector), mapping function (like normalise(), cumsum() etc., giving a vector of the same length as the input vector) and finally, vector reducing function (like diff() which produces result vector of a length different from the length of input vector). Optional or mandatory additional arguments required by some functions (e.g. norm type for norm() or normalise() functions) can be passed as named arguments in '...'.
