在R scatter3d包中检索回归曲面的数据或函数

Question

Does anyone know if it is possible to view the data used for plotting the surface regression in the scatter3d package in R? What I want is to be able to somehow view the formula (or function) for the surface regression that is be applied to my data points in the scatter3d package in R.

Answer 1

Edit: I'm guessing you're using scatter3d from the IPSUR package.

Per the help page, "Value

scatter3d not return a useful value; it is used for its side-effect of creating a 3D scatterplot. indentify3d returns the labels of the identified points."

You might want to experiment with scatterplot3D over at CRAN to see if its returned values (functions) are of use.

You might be able to dig into the source of scatter3d and fork a version which returns the data.
