attrDataItem-methods {graph} | R Documentation |
Get and set attributes values for items in an attrData object
Description
The attrDataItem
method provides get/set access to items stored
in a attrData-class
object.
Usage
attrDataItem(self, x, attr)
attrDataItem(self, x, attr) <- value
Arguments
self |
A attrData-class instance |
x |
A character vector of item names |
attr |
A character vector of length 1 giving the attribute
name to get/set. Note that the attribute name must have already been
defined for the attrData object via
attrDefaults . If missing, return a list of all
attributes for the specified nodes. |
value |
An R object to set as the attribute value for the
specified items. If the object has length one or does not have a
length method defined, it will be assigned to all items in x .
If the length of value is the same as x , the
corresponding elements will be assigned. We will add an argument to
indicate that the value is to be taken as-is for those cases
where the lengths are the same coincidentally. |
