| attach.env {Zelig} | R Documentation |
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.
attach.env(f, env = NULL, ...)
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 |
the original function “f” with a different environment attached to it.
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.
