Hello, I did some nice grafics using plot 3d and scatter3d. Is there a, hopefully not too complicated way, to transform these dynamic, three-dimensional and interactive grafics in a kind of executable file? I want to show and send them via e-mail to projekt partners who don`t use GNU R and who are not used to do programming. So the result should be quite comfortable to execute for them in

It worked very well but when I tried to compile the latex file I get this error message: !

Hello! I want to calculate simultaneous confidence intervals for a nominal variable with three categories: "yes", "no", "partially" and I expect that far more than 5 samples fall into each category.
