Here is one way and how to access the data:


> x
      [,1] [,2]
 [1,]   -1 0.05
 [2,]    1 0.05
 [3,]    1 0.00
 [4,]    0 0.05
 [5,]   -1 0.00
 [6,]    0 0.10
 [7,]    1 0.10
 [8,]   -1 0.00
 [9,]   -1 0.10
[10,]    0 0.05
[11,]    0 0.10
[12,]   -1 0.10
[13,]    1 0.00
[14,]   -1 0.05
[15,]    1 0.00
> tapply(x[,1], x[,2], table)
$"0"

-1  1
 2  3

$"0.05"

-1  0  1
 2  2  1

$"0.1"

-1  0  1
 2  2  1

> y <- tapply(x[,1], x[,2], table)
> y[["0"]]["-1"]
-1
 2
> y[["0.1"]]["0"]
0
2
