Dear all, I want to find out the mode for a data set, anyone knows how to do it in R? I tried the codes below, but it seems too long: tt<-table(data1) #get the frequency tables of data1 oo<-order(tt); #get the order of frequencies len<-length(tt) #the length of the tables mm<-oo[len]; #the last number of oo is the position tt[mm] #we can get the mode Thank you everybody first! Regards, Long Yu

See ?which.max Uwe Ligges
Yhe question of finding the mode of a dataset has been discussed previously in the list not only for categorical data : search "How can I get the mode" in the search engine of the list. Hope this helps. Romain. Selon Uwe Ligges <ligges at statistik.uni-dortmund.de>:
