mvbutils (version 2.5.4)

hack: Modify standard R functions, including tweaking their default arguments

Description

You probably shouldn't use these...

Usage

hack( fun, ...)
 assign.to.base( x, what=,  where=-1, in.imports=, override.env = TRUE)

Arguments

fun

a function (not a character string)

...

pairlist of arguments and new default values, e.g. arg1=1+2. Things on RHS of equal signs will not be evaluated.

x

function name (a character string)

what

function to replace x, defaulting to "replacement." %&% x

where

where to find the replacement function, defaulting to usual search path

in.imports

usually TRUE, if this is being called from an .onLoad method in a namespace. Make sure any copies of the function to be changed that are in the "imports" namespace also get changed. See Description.

override.env

should the replacement use its own environment, or (by default) the one that was originally there?
