[R] how to plot three dimension data to filled contour plot or surface plot in R Ask Question

[dncdd]

ENV 

R 3.3.2

When I have data like:

    rdn<-c(0.8,1.8,2.8)
    tdn<-c(1,2,3,4,5,6,7,8,9)
    
    idn<-matrix(c(0.3, 0.3, 0.3, 0.2, 0.2, 0.4, 0.1, 0.1, 0.5, 0, 0.2, 0.5, 0, 0.3, 0.6, 0, 0.4, 0.6, 0, 0.4, 0.6, 0, 0.5, 0.7, 0, 0.5, 0.7), nrow=9, ncol=3, byrow=T)

And the matrix looks like(3*9 = 27 data elements):

    0.3, 0.3, 0.3, 
    0.2, 0.2, 0.4, 
    0.1, 0.1, 0.5, 
    0, 0.2, 0.5, 
    0, 0.3, 0.6, 
    0, 0.4, 0.6, 
    0, 0.4, 0.6, 
    0, 0.5, 0.7, 
    0, 0.5, 0.7

Then I can get a filled.contour with parameters x,y,z. x is tdn, y is rdn, z is the matrix. I already get this.

 
**My current problem** is:

What If I have three dimension data

    r1dn<-c(0.8,1.8,2.8)
    r2dn<-c(0.8,1.8,2.8)
    tdn<-c(0.1,0.2,0.3,0.4,0.5,0.6,0.7,0.8,0.9)

And (3*3*9 = 81 data elements):

     0.8                  1.8                  2.8
    0.8  1.8  2.8       0.8  1.8  2.8        0.8  1.8  2.8

    --------------- 81 ---- elements ----------------------

    0.3, 0.3, 0.3,      0.3, 0.3, 0.5,       0.3, 0.3, 0.3, 
    0.2, 0.2, 0.4,      0.2, 0.4, 0.4,       0.4, 0.2, 0.5,
    0.1, 0.1, 0.5,      0.2, 0.3, 0.5,       0.4, 0.4, 0.5, 
    0, 0.2, 0.5,        0.2, 0.2, 0.6,       0.4, 0.5, 0.6, 
    0, 0.3, 0.6,        0.3, 0.3, 0.6,       0.5, 0.5, 0.7, 
    0, 0.4, 0.6,        0.2, 0.5, 0.7,       0.5, 0.6, 0.7, 
    0, 0.4, 0.6,        0, 0.5, 0.6,         0.5, 0.6, 0.9,  
    0, 0.5, 0.7,        0, 0.6, 0.8,         0.5, 0.7, 0.8, 
    0, 0.5, 0.7         0, 0.6, 0.8          0.5, 0.8, 0.9       


I googled many surface and contour codes but I still not find some code for three dimension data yet. How to do that in R? Say, x is r1dn, y is r2dn, z is tdn, what about the three dimension data? Does ggplot can plot three dimension filled contour or surface plot? Or another alternative solutions?

All I expected is a 3d plot with color changes smoothly and no grid on it.

Looks like:

 
no grid for next three figures

 
 
 
Those should be 3d filled contour or 3d surface plot.

Thanks for your time.
