R in Microsoft Word: SWord
SWord integrates R seamlessly into Microsoft Word. SWord currently supports Microsoft Word versions 2000, 2002 (XP), 2003, 2007 and 2010.
Use R commands in Word fields to embed statistics and figures into your documents. Using SWord is more than just Copy & Paste. You can edit the R code, you can change the data and simply run SWord again to process the document.
SWord preserves the R code used to create the statistics and figures even when non-R-users are modifying the document. You do not have to have R or SWord installed to modify the document.
