Dear list, I have following table ee<-table(ID,Day) ee Day ID 2 3 4 5 6 7 9 10 14 16 35 5 0 0 3 1 0 0 5 0 0 36 0 0 0 0 0 0 0 1 0 0 43 13 15 15 0 0 13 13 15 13 15 46 0 1 0 0 0 0 0 0 0 0 58 0 0 0 0 0 0 4 4 0 0 and want to calculate the sum for each row and column and then append the sums to the table matrix. kk<cbind(ee,as.matrix(apply(ee,1,sum))) dd<-rbind(kk,apply(ee,2,sum)) Warning message: number of columns of result is not a multiple of vector length (arg 2) in: rbind(1, kk, apply(ee,2, sum)) rownames(dd)<-c(rownames(dd)[-6],"Total:") colnames(dd)<-c(colnames(dd)[-11],"Total:") I got a table as wanted (see below), except that the variable names Day and ID are missing. Is there a way to add back these variable names to the table "dd" as shown in "ee". Also I got a warning message that I'm not exactly know how to skip. Can I make the table "dd" in a different and easier way ? Any suggestions are highly appreciated. Thanks, Tom dd 2 3 4 5 6 7 9 10 14 16 Total: 35 5 0 0 3 1 0 0 5 0 0 14 36 0 0 0 0 0 0 0 1 0 0 1 43 13 15 15 0 0 13 13 15 13 15 112 46 0 1 0 0 0 0 0 0 0 0 1 58 0 0 0 0 0 0 4 4 0 0 8 Total: 18 16 15 3 1 13 17 25 13 15 18
