Dear R,

I have data like this

I I D I D D D D D I D I D I D I D I D D D I D D I I I I
I I I I D I D I D I I I D I I I D I D I D I D I 0 0 I I I I I I I
I I D I D I D I D I I I D I I I D I D I D I D I I I D I I I I I

Now for each row i want to make count in groups
2 in each group for all possible groups like for each row
count of All I I in 1 group then
all D I and
D D in another group

result should be count of each group in there respective rows


Regards
GRR
