...m(y~x1+x2) ##let's only consider the partial residuals when x2 is dropped from the model plot(residuals(mod,type="partial")[,2],residuals(update(mod,.~.-x2),type='response')) abline(0,1) ##1:1 line ##why do the points not all fall on the 1:1 line?

Dear r-helpers, Can one save a dynamic graphic produced by rgl, e.g.: open3d(); x <- sort(rnorm(1000)); y <- rnorm(1000); z <- rnorm(1000) + atan2(x,y); plot3d(x, y, z, col=rainbow(1000), size=2) as a dynamic figure that can be embedded in a pdf? _____________________________ Professor Michael Kubovy University of Virginia Department of Psychology USPS: P.O.Box 400400
