When I run your code, I get a different error:
> j=10; ss=150; r=array(0 , c( j , ss )); rr=array(0 , c( j , ss ));
r1=array(0 , c( j-1 , ss )); r2=array(0 , c( j-1 , ss ));
> r3=array(0 , c( 2 , ss ))
>
> for(i in 1:j-1){
+ r1[ i , ] <- r[ j+1, ]-r[ j, ]; r2[ i , ] <- rr[
j+1, ]-rr[ j, ]
+ r3[ i,]=rbind(r1[ i, ], r2[ i, ])
+ }
Error: subscript out of bounds

This is probably due to 'r' being dimensioned (j,ss) and you are referencing
'r[j+1,]' which is r[11,]. Also I think you want "for(i in 1:(j-1))",
notice the difference:
> 1:j-1
[1] 0 1 2 3 4 5 6 7 8 9
> 1:(j-1)
[1] 1 2 3 4 5 6 7 8 9
