Hi, a few years ago I wrote a script which grabs a .csv file and transforms this in a (beautifull) MS Word document, with all the calculations and plots required. All calculations in the report were verified manually against some datasets with known results to validate the use of the script, as this is required before we may use the script. Now we want to upgrade to R 2.15, but my script was validated under R 2.11. If my function would return just a dataset with some values, it would be easy to compare between both versions, but not when I have to read about 100 pages in a word document to check everything. How does one deal with this kind of situation? Or if it's not possible, how to avoid this kind of problems when output in MS Word is required?
