env_get() extracts an object from an enviroment env. By default, it does not look in the parent environments. env_get_list() extracts multiple objects from an environment into a named list.

env_get(env = caller_env(), nm, inherit = FALSE)

env_get_list(env = caller_env(), nms, inherit = FALSE)



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

nm, nms

Names of bindings. nm must be a single string.


Whether to look for bindings in the parent environments.


An object if it exists. Otherwise, throws an error.


parent <- child_env(NULL, foo = "foo") env <- child_env(parent, bar = "bar") # This throws an error because `foo` is not directly defined in env: # env_get(env, "foo") # However `foo` can be fetched in the parent environment: env_get(env, "foo", inherit = TRUE)
#> [1] "foo"
