[kepler-dev] [kepler-users] Reg: 3D plotting in Kepler

[Dan Higgins]

Hi Niket,
    First, I recommend that you go to www.kepler-dev.org and download 
the Beta2 version of Kepler. If you are working with the Windows 
version, R is included in the installer and you avoid problems with 
getting R and Kepler working together! (also the alpha6 version is now 
obsolete).

    Also attached is a Kepler workflow that shows how an RExpression 
actor can create a 3D plot. In this case, it is completely genrated by 
the R script, but it could come from input ports added to the 
RExpression actor.
