R counting the occurrences of similar rows of data frame?

Ok, let's first do it in the easy case where you just have one column.

Okay I used the answer I had on another question and worked out a loop that I think will work. This is what I'm going to use.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
