table
uses the cross-classifying factors provided as arguments
to build a contingency table of the counts at each combination
of factor levels.## Simple frequency distribution table(rpois(100,5)) data(warpbreaks) attach(warpbreaks) ## Check the design: table(wool,tension) data(state) table(state.division, state.region) data(airquality) attach(airquality) # simple two-way contingency table table(cut(Temp, quantile(Temp)), Month)
