Usage
## S3 method for class 'Object}(this, private=FALSE, fields=NULL, excludeFields=NULL, overwrite=TRUE, envir=parent.frame(), ...)':
attachLocallyundefined
Attaches an Object locally to an environment. By default, the fields of the Object are attached to
the parent frame, that is, the calling environment.
- private
{If TRUE
, private fields are included, otherwise not.
This is only effective if fields==NULL
.}
- fields
{A character
vector
specifying elements to be copied.
If NULL
, all elements are considered.}
- excludeFields
{A character
vector
specifying elements not to
be copied. This has higher priority than fields
.}
- overwrite
{If FALSE
, fields that already exists will not be
copied.}
- envir
{The environment
where fields are copied to.}
- ...
{Not used.}
Returns (invisibly) a character
vector
of the fields copied.
