Hi greg I did not know the function and it is very nice.. my problem is..... take the examples of the help page of tkexamp(): they are 2d graphs where you can changes plot options; I'm pretty sure you can do what I can do in Rstudio; this an Rstudio example:
library(manipulate) xx<-abs(rnorm(30,5,1)) yy=log(xx) plot(xx,yy) zz<-1/xx manipulate( plot(xx,yy^zz,xlim=range(cbind(xx,yy*zz),ylim=range(cbind(xx,yy*zz)))), zz=slider(-1,1,step=0.1)) using the control under the small gear button at high left corner of the graph you can change the plot **in function** of the zz parameter I THINK it can be replicated using tkexamp() and I will try; I did not yet because I want to answer you immediately..... however I want to do the same things on a 3D graph; under the help of function rotate.wireframe() I saw the closest thing to what I have in my mind..... I tried to pass to tkexamp() threee variables using scatterplot3d() but I receive an error it is possible to combine the potential of tkexamp() --- or manipulate---- that allows to change the graph in function of a given values of x and the 3d visualization of rotate.wireframe() ? This could replicate what you can see on the web address of Mathematica I posted in my previous post: http://reference.wolfram.com/mathematica/tutorial/IntroductionToManipulate.html I saw that under Rstudio the package "manipulate" can handle objects coming from scatterplot3d() but the point of view remains fixed; you cannot rotate it dinamically as in a rgl scene or even in a rotate.wireframe graph; on the other hand.....I cannot find a solution to manipulate a 3d plot of a rgl scene in function of a given parameters that changes the values of x,y and z as you can possibly do in tkexamp() or manipulate(); The best could be to integrate the potential of tkexamp() and rotate.wireframe() together could you indicate me the other solutions you refer in your previous message? Anyway...thanks a lot!! Awaiting an answer from you I will try to play with TeachinDemos more accurately best regards Paolo ________________________________ Da: Greg Snow [538...@gmail.com] Inviato: lunedì 8 luglio 2013 17.53 A: Paolo Piras Cc: r-sig-geo@r-project.org Oggetto: Re: [R-sig-Geo] R or R studio 3d manipulate If you can write a function that takes the arguments that you want to change and creates the graph you want to see, then there are several tools that can be used to create controls that will change those arguments. The `tkexamp` function in the TeachingDemos package is one such tool, but there are others as well. If you can give a more specific example of what graph you would like and what values you would like to change then we may be able to give a more specific example.
