Dear R users,
I want to group numerical values in classes with different size and count
the values for each classes.

My data is in this forma:
 d  15  12,5  30,4  20,5  80,4  100,5  8,2  40,5  33  21  11
And I want the group them in classes with 4 (5,....etc) cm size like this:
 class d  16  16  32  24  84  104  12  44  36  24  12
and final to count values for each class:
class d                               n  12 2  16 2  24 2  32 1  36 1  44 1
84 1  104 1  Total 11

Thank you!
