The "tanagra.xla" add-in for Excel contributes to the wide diffusion of Tanagra. The principle is simple. It is to embed a Tanagra menu in Excel. Thus the user can run statistical calculations without having to leave the spreadsheet. It seems simplistic. But this feature facilitates immensely the work of data miner. Indeed, the spreadsheet is one of the most used tools for preparing dataset (see KDNuggets Polls: Tools / Languages for Data Cleaning - 2008). By embedding the data mining tool in the spreadsheet environment, it avoids to the practitioner the tedious and repetitive manipulations: importing the dataset, exporting the dataset, checking the compatibilities between data file formats, etc.
The installation and the use of the "tanagra.xla" add-in under the previous versions of Office are described elsewhere (Office 1997 to Office 2003). This description is obsolete for the latest version of Office because the organization of the menus is modified for these versions i.e. Office 2007 and Office 2010. And yet, the add-in is still operational. In this tutorial, we show how to install and to use the Tanagra add-in under Office 2007 and 2010.
This transition to recent versions of Excel is absolutely not without consequences. Indeed, compared to the previous Excel versions, Excel 2007 (and 2010) and can handle more important rows and columns. We can process a dataset up to 1,048,575 observations (the first line corresponds to the variable names) and 16,384 variables. In this tutorial, we will treat a database with 100,000 observations and 22 variables (wave100k.xlsx). This is a version of the famous waveform database. Note that this file, because of the number of rows, cannot be manipulated by earlier versions of Excel.
The process described in this document is also valid for the SIPINA add-in (sipina.xla).
