Hi all!

 

I'm very new to R, and I'm having trouble figuring out how to go from a file
of points that I have to a 3d surface plot of the data. I typically have
something like this:

 

X          Y          Z

0.005    0.023    34.45

0.0035  0.63      28.48

.

 

I've tried looking at the persp and wireframe packages, and the rgl package,
but I can't seem to figure out how to use any of them. I tried to take the
rgl.surface3d example and use it for myself, and this is what I have so far:

 

setwd(".")

 

data <- read.csv("data.csv",header=T)

 

x <- data$X

y <- data$Y

z <- data$Z

 

open3d()

surface3d(x, y, z) 

 

That gives me the following error:

 

Error in rgl.surface(x = c(0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,  : 

  y length != x rows * z cols

 

I have no idea what it is trying to tell me there. Would anyone mind helping
me out?

 

 

Wesley
