Hi Emmanuel, We are doing some work along these lines. See www.OpenI.org for details of our open souce OLAP solution & contact our CTO, Sandeep Giri (via link on that site), for details. We haven't released any R integration yet, but we are doing some things internally & it is on the OpenI development roadmap.
I think OLAP definitely needs integration with some hard analytics. Sure, our business analysts are very comfortable moving around in OLAP space & come up with some amazing insights, but OLAP just provides simple counts, sums etc. No sense of estimated errors or tests of significance. And, of course, no advanced techniques. One technical point, some methods would require a "drill-through" to the underlying data set. For example, while a mosaic plot can be generated from a 2-dimensional OLAP result table, generating a box plot corresponding to a OLAP bar chart (my personal favorite) needs the raw data points. We welcome everyone interested in this idea to join in the discussion & effort. The OpenI forum http://sourceforge.net/forum/?group_id=142873 is probably a better place than here.
