How to make a better surface 3dplot with discontinuities in data in R?

Question

I would like to make a surface 3d plot of the data below in R. I already made some figures. However, there are some discontinuities and this effects the plots. Do you have any idea how to make 2 surfaces of it or make it look nice? Thank you! :)

library(scatterplot3d) 
library(rgl) 
library(car) 
x<- b[1:11,2]
y<-seq(-1,1,length.out=21)
z<-matrix(data=b$A,nrow=11,ncol=21)
persp(x,y,z,theta=30, phi=30, col="lightblue",expand = 0.5,shade = 0.2,xlab="c", ylab="h", zlab="A")
scatterplot3d(b$c,b$h,b$A)

surfaceplot scatterplot

Answer 1

First of all you are not really making a wireframe, use the wireframe from the lattice package.

wireframe(A ~  c + h,drape = TRUE,pretty = TRUE, data = df)

This is the result with your data

You still have some wonky Data inbetween, but this should solve the empty spaces.
