[R] keep adding elements to the matrix

[Nick Sabbe]

Hello Alex.

I'm a bit confused by your english, but what I guess you want is:
x<-final[-1] - final[-length(final)]
y<-2*final[-1]

result<-cbind(x=x, y=y)

Good luck.

Subject: [R] keep adding elements to the matrix

Hello everyone,
I would like to create a "dynamic" array to keep storing number in it

for (i in c(2:length(final))){
    myarray <-final[i]-final[i-1]
    myarray2<-2*final[i]  
  }



At the end I would like to use myarray as the x values of an array
and the myarray2 as the yvalues of the same array.
I tried cbind but it didnot work.

Could you please help me with that?

Best Regards
Alex
