workbook-class: Class "workbook"

Description

This is XLConnect's main entity representing a Microsoft Excel workbook. S4 objects of this class and corresponding methods are used to manipulate the underlying Excel workbook instances.

Objects from the Class

Objects can be created by calls of the form loadWorkbook(filename, create). This is a shortcut form of new("workbook", filename, create) with some additional error checking.

Slots

filename:

Object of class character which represents the filename of the underlying Microsoft Excel workbook.

jobj:

Object of class jobjRef (see package rJava) which represents a Java object reference that is used in the back-end to manipulate the underlying Excel workbook instance.

Note: The jobj slot should not be accessed directly. workbook objects should only be manipulated via the corresponding methods.
