These ellipses would be based on the confidence intervals for the slope and intercepts (forming the major and minor axis of each ellipse), and the correlation in the slope and intercepts. The ellipse function in the car library

I am trying to make a graph with 4 scatter matrixes plots and couldn't do it. While trying to find a solution for this I also came across the idea of giving different values to the same argument for each of the lower and upper function but couldn't do it.

Hi, I''m pretty new to ruby and rails, so apologies if this has been covered before (I couldn''t find a thread on it). I want to retrieve a count of records held in the DB for every distinct value of an attribute.
