Hi, exists("foo", inherits=TRUE) check whether an object named "foo" exists, and get("foo", inherits=TRUE) retrieves it. I'm looking for a similar function to exists() that returns the environment where the object "foo" exists, iff at all. If not found, NULL is returned. Does that exist?
EXAMPLE #1: > sample2 <- base::sample > env <- where("sample2", inherits=TRUE) > env <environment: R_GlobalEnv> Note the difference to: > obj <- get("sample2", inherits=TRUE) > environment(obj) <environment: namespace:base> EXAMPLE #2: > a <- 1 > foo <- function() { b <- 2; list(a=where("a", inherits=TRUE), b=where("b", > inherits=TRUE)) } > foo() $a <environment: R_GlobalEnv> $b <environment: 0x000000000b7d2798> > foo() $a <environment: R_GlobalEnv> $b <environment: 0x000000000b7d23e0> I do understand that I can implement such a function myself, but I prefer not to.
