R help - Sep 2010 - 3D Graphics

Dear All,

I have made a scatter plot and placed a plane within it using scatterplot3d.
However, I have been asked for the data points to be a surface plot or have
the plane more closely resemble the data rather than show trends.

I have since tried to use the rgl package. Why doesn't this package use the
window which already contains graphics?

I have one axis with decreasing values and two others with increasing
values, hence I get an error message when I've tried using pers3d.

Are there anyother ways in which I can create a surface plot?

Thank you,

Jo

The usual graphics drivers don't support OpenGL, which rgl uses.  It 
would probably be possible to implement a standard R graphics device on 
an rgl canvas, but I don't know anyone who has done that.

You can always plot against negative x without labels, and add the 
labels for positive x later (using persp3d and axis3d).
