Analog of 'ave' in plyr?

You can shorten the ddply code somewhat by using transform.

I recently wrote a blog post comparing ave, ddply, and data. Table in terms of speed. I would recommend you take a look at data.

Table, it might prove beneficial. Sorry in advance if anyone takes offence to the self promotion.

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.
