Remove bindings from an environment

env_unbind() is the complement of env_bind(). Like env_has(), it ignores the parent environments of env by default. Set inherit to TRUE to track down bindings in parent environments.

Usage
env_unbind(env = caller_env(), nms, inherit = FALSE)
Arguments
env

An environment or an object bundling an environment, e.g. a formula, quosure or closure.

nms

A character vector containing the names of the bindings to remove.

inherit

Whether to look for bindings in the parent environments.

Value

The input object env with its associated environment modified in place, invisibly.

Examples
# NOT RUN {
data <- set_names(as_list(letters), letters)
env_bind(environment(), !!! data)
env_has(environment(), letters)

# env_unbind() removes bindings:
env_unbind(environment(), letters)
env_has(environment(), letters)

# With inherit = TRUE, it removes bindings in parent environments
# as well:
parent <- child_env(NULL, foo = "a")
env <- child_env(parent, foo = "b")
env_unbind(env, "foo", inherit = TRUE)
env_has(env, "foo", inherit = TRUE)
# }
