It could, though it seems a bit clumsy: xy<-round(rexp(20),1) H<-hist(xy,breaks=(-0.05+0.5*(0:8)),plot=FALSE) brks<-H$breaks ; cts<-H$counts Tbl<-rbind(NULL,cts) brlabs<-paste(brks[1:(k-1)]+0.05,"-",brks[2:k]-0.05,sep="") colnames(Tbl)<-brlabs Tbl # 0-0.4 0.5-0.9 1-1.4 1.5-1.9 2-2.4 2.5-2.9 3-3.4 3.5-3.9 #cts 5 4 6 3 0 1 1 0 One could fiddle with formatting to replace 0 by 0.0 and 3 by 3.0, and set rownames=NULL; but I don't see how to get the counts placed in the "middle" of the range. But it's better than nothing, I suppose!
