Now what? :-)

certainly it's not
pairs(d)

contents of rstuff/data.dat:

 angle  resp  ID
 -90      182  1
 -60      137  1
 -30      123  1
 0    67  1
 30   32  1
 60   12  1
 90    13  1
-90      178  2
 -60      111  2
 -30      137  2
 0    94  2
 30   59  2
 60   1  2
 90    19  2

I actually have a lot more than 2 experimental units (ID)...

Thanks for any help
