Assuming that's qplot from ggplot2, it's trying to pass span to the Point Geom which doesn't recognize it. I highly suggest moving away from using qplot and working with the stat_s and geom_s directly with ggplot(). On Sat, Jan 23, 2016 at 8:46 AM, Jeff Reichman wrote: > R-Users > > > > Anyone se

Alternatively you might use log(p/1-p) as your dependent variable and use OLS with robust standard errors. Much of your inference would be analogous to a logistic regression John C Frain 3 Aranleigh Park Rathfarnham Dublin 14 Ireland www.tcd.ie/Economics/staff/frainj/home.html mailto:fra...@tcd.ie
