as.environment: Coerce to an Environment Object

Description

A generic function coercing an R object to an environment. 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 class for which an as.environment method is found, that is used.

Value

The corresponding environment object.

See Also

environment for creation and manipulation, search; list2env.

Examples

# NOT RUN {
as.environment(1) ## the global environment
identical(globalenv(), as.environment(1)) ## is TRUE
try( ## <<- stats need not be attached
    as.environment("package:stats"))
ee <- as.environment(list(a = "A", b = pi, ch = letters[1:8]))
ls(ee) # names of objects in ee
utils::ls.str(ee)
# }
