help with xyplot
Hi, I make a graphic using xyplot, it is very good. xyplot((ocorrencia/isca)~frag|especie) But I need to plot a curve for each especie's plot. I try to use panel.abline and others panel., but I dont succeed. I need to plot the function exp(a+b*x+c*x^2)/1+exp(a+b*x+c*x^2), a b and c are different for each especie. Normally I use the curve function to add a curve in a points graphics, but it dont work with xyplot. Anybody have any idea? Thanks Ronaldo
