[R] 3-D plot of a bidimensional lognormal distribution

2012-06-19 Thread masterpatacca
Hi and thanks in advance to everyone who will be able to help me. I have 2 independent lognormal distributions with different means and sd. I want to plot them togheter in a 3D plot. How can i do this??? I'm getting crazy... Thanks Ale -- View this message in context:

Edwin, the problem is that the underlying R code treats the lab argument as something that should be approximate in some way. In your case, you can say, e.g.: par(lwd=3) scatterplot3d(. lab= c(5,hostLength*2), .) Best wishes; uwe Edwin Sendjaja wrote:

Hi Uwe, Thanks for your answer. What is the different between rgl and scatterplot3d? I dont need a graphik like vulcano. I just need 3D-dot-plot. Am Donnerstag, 17. April 2008 09:03:17 schrieb Uwe Ligges: Edwin Sendjaja wrote: Hello, I've got some problems. I hope someone can help me.

[R] 3-D plot of likelihood
