sort data.frame and contour()
...column. sort() does it for a single vector but not for the whole data. order() does it if there are relations between the columns but in my case it is simply a data.frame. Further, I would like to plot other data, pop.size<- c(800, 800, 1500, 1000, 158, 300, 740, 250, 2000, 1500, 250, 700) fem.frek<- c(0.054, 0.099, 0.04, 0.113, 0.234, 0.241, 0.099, 0.182, 0.176, 0.175, 0.126, 0.09) rel.femfec<- c(0.975, 0.713, 1.035, 1.745, 0.77, 1.162, 0.94, 0.636, 2.12, 2.159, 0.428, 1.217) emil.data<- as.data.frame(cbind(pop.size, fem.frek,asfem.frek,rel.femfec)) attach(emil.data) contour(pop.siz...

summary(polr.object)
...I have used polr in MASS but I am uncertain about the summary(polr.object) interpretation and would be happy for help on that. This is my summary: > summary(shade.polr) Re-fitting to get Hessian Call: polr(formula = as.ordered(shade) ~ as.factor(objekt), data = sof, weights = as.numeric(frek)) Coefficients: Value Std.
