    args: &[Arg],
    env: &Environment,
    context: &BuiltinContext<'_>,
) -> Result<RValue, RError>

Remove objects from an environment.

@param … names of objects to remove (bare symbols or character strings) @param list character vector of names to remove @param envir environment from which to remove (default: calling environment) @return NULL (invisibly)
