Hi, I have a data set with three variables,X Y and Time. X and Y are the coordinates of points, i want to join these points according to the Time sequence using arrows? Demo Example data: > x<-c(1:6) > y<-c(1:6) > time<-c(6:1) > data<-cbind(x,y,time) > data x y time [1,] 1 1 6 [2,] 2 2 5 [3,] 3 3 4 [4,] 4 4 3 [5,] 5 5 2 [6,] 6 6 1 I hope to join the six points with points' time=1 as starting point and points' time=6 as endpoint. So the sequence is time=1,2,3,4,5,6 and join the corresponding points with arrows. Any ideas on it?
