packList: Pack a List with Objects

Description

Pack a list with existing objects using names only.

Usage

packList(stuff, target="PBSlist", value, penv=NULL, tenv=.PBSmodEnv)

Arguments

stuff

string vector of object names

target

target list object

value

an optional explicit value to assign to stuff

penv

parent environment (default) or user-specified environment where stuff resides

tenv

target environment where target list is or will be located

Value

No value is returned

Details

A list object called target will be located in the tenv environment. The objects named in stuff and located in the penv environment will appear as named components within the list object target.

If an explicit value is specified, the function uses this value instead of looking for local objects. Essentially, stuff = value which is then packed into target.
