summary(columnvariable ~ rowvar1+rowvar2+...., method='reverse') will do what you want, if you are interested in separate summaries for each row variable.  This uses the summary.formula function in the Hmisc library (http://hesweb1.med.virginia.edu/biostat/s/Hmisc.html) for which there are plot, print, and latex methods for formatting the output.  For 2-way cross-classified summaries see method='cross'.
