restrict_environment {convdistr} R Documentation

## Build a new function with a smaller environment

### Description

As standard feature, R include in the environment of a function all the variables that are available when the function is created. This, however is prompt to leak reference when you have a factory of function and they are created within a list.. it will include all the component of the list in the function environment. To prevent that, the random generator functions are encapsulated with a restricted environment where only the variables that the function requires to work are included

### Usage

restrict_environment(f, ...)


### Arguments

 f input function ... define the set of variables to be included as variable = value.

### Value

new function with a restricted environment

John J. Aponte

### Examples

a = 0
b = 1
myfunc <- restrict_environment(
function(n) {
rnorm(meanvalue, sdvalue)
},
meanvalue = a, sdvalue = b)

myfunc(10)
ls(envir=environment(myfunc))
