proteins 
#Age

0.6777777

#Class
Type A
Type B

Type K

I wish to get a table that reads as follows
         0-0.02   0.02-0.04 0.04-0.06 ..... 0.78-0.8
Type A    15       20           5             8
Type B     8        6 ....
.

Type K     1        0           7

I would appreciate your input regarding the
appropriate functions to use for this purpose
