Dear all,
I have two coordinates vectors, say X and Y of length n.
I want to generate for each couple of coordinates X1,Y1 X2,Y2
X3,Y3....Xn,Yn a random coordinate which is located in a square define
as X +/- dx and Y +/- dy.
I saw the runif function which can generate for just one value at a time
what I want : runif(1, X - dx, X + dx) for X and runif(1, Y - dy, Y +
dy) for Y.
I would like to know if there is not a more powerfull way in R to
generate directly the set of random coordinates.
Regards
