Thanks to all, I did eventually come up with a solution which involved sub-setting the data first into categories, making an empty plot, and then plotting rectangles. I really like the ggplot2 and I will use that next time. My ugly script is below Thanks, Daisy plot(1, xlim=c(5,45),ylim=c(0,1

Hi, I had a questions about doing ridge regression in R. Why is it that when I try this on datasets with more predictors than samples (p>n) using lambda=0, it still finds coefficients for all predictors? I thought when lambda=0, it should be like ordinary regression and therefore not find coe
