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

Are there anyother ways in which I can create a surface plot?
Thank you,
Jo
