I have a data set X. I got the distance matrix using : X2 <-daisy(X). I made: X3 <- sqrt(X2). To calculate I did This : AFTD <- cmdscale(X3) To obtain the draphics of AFTD I use : plot(AFTD). The plotting result is not what I was expecting and not true because I got curviligne. Can someone help me to solve that. I some options to use. Lassana TOURE. [[alternative HTML version deleted]]
