Hi Etienne, Somebody asked a somehow related question recently. http://tolstoy.newcastle.edu.au/R/help/06/06/29485.html
Take a look at cut? table? and barplot? i.e. #Creates fake data from uniform(0,30) x=runif(50, 0,30) #Creates categories rain=cut(x,breaks=c( 0, 1,2.5,5, 10, 20, Inf)) #Creates contingency table of categories tab=table(rain) #Plots frequencies of rainfall barplot(tab) I hope this helps!
