scatterplot matrix question
I would like a scatterplot matrix and a correlation matrix for the following set-up. The data (dataframe d) are like this: angle resp -90 182 -60 137 -30 ...etc 0 30 60 90 ...etc I would like each cell in the matrix to be the scatterplot of the responses for each pair of angles ( -90 vs -60, -90 vs -30, etc). Same for the correlation matrix. Please tell me what to do. Thanks very much! Bill
