localfuncs {mvbutils} | R Documentation |
"Declare" child functions, allowing much tidier code
Description
Only call this within a function, say f
. The named functions are copied into the environment of f
, with their environments set to the environment of f
. This means that when you call one of the named functions later in f
, it will be able to see all the variables in f
, just as if you had defined the function inside f
. Using localfuncs
avoids you having to clutter f
with definitions of child functions. It differs from mlocal
in that the local functions won't be changing objects directly in f
unless they use <<-
– they will instead have normal R lexical scoping.
Usage
localfuncs(funcs)
Arguments
funcs |
character vector of function names |

Examples
inner <- function( x) {
y <<- y+x
0
}
outer <- function( z) {
# Multiply z by 2!
y <- z
localfuncs( 'inner')
inner( z)
return( y)
}
outer( 4) # 8
