Description
A generic function coercing an R object to an[environment](../../base/help/environment.html). A number or a character string is converted to the corresponding environment on the search path.
Usage
as.environment(x)
Arguments
| x | an R object to convert. If it is already an environment, just return it. If it is a positive number, return the environment corresponding to that position on the search list. If it is -1, the environment it is called from. If it is a character string, match the string to the names on the search list. If it is a list, the equivalent of list2env(x, parent = emptyenv()) is returned. If is.object(x) is true and it has a classfor which an as.environment method is found, that is used. |

Details
This is a primitive generic function: you can write methods to handle specific classes of objects, see InternalMethods.
