attach.env: Attach Variables to a Function

In IQSS/Zelig4: Everyone's Statistical Software

Description

Returns a function, specified by the user, with the variables of a specified environment attached. This, in essence, allows programmers to write functions that have forms of private memory. This makes the function behave similarly to an object.

Usage

  attach.env(f, env = NULL, ...)

Arguments

f	a function which will be modified
env	an environment variable which will be attached to the function being returned
...	arbitrary key-value paired parameters which will be assigned to the environment of the function being returned

Value

the original function “f” with a different environment attached to it.

Note

This function is used by Zelig to ensure that particular method calls - param, qi, bootstap - will contain the private variables: “.fitted”, “.model”, “.call” and “.env” which respectively contain the fitted model object, the name of the zelig model being invoked, the original call to the model-fitting function and the environment in which to call the function call.
