Re: [R] Contour plot on a triangular mesh

I'm not sure if this is appropriate. If the sum of your variables is always the same constant, then you might try a Ternary plot ( http://en.wikipedia.org/wiki/Ternary_plot ). The "vcd" package can make ternary plots. On 01/20/2012 02:56 PM, Roary wrote: I have two observed categorical variab

Re: [R] Plotting GEE confidence bands using "predict"

without confidence bands, per se. The resulting figure has a vertical confidence bar at every value of X. It's kind of a cool effect and just as good, I guess, as the standard regression line plot with confidence bands. Thanks again Shige for pointing me in the right direction.cheers,Jason On Mon, Oc
