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?
