在R？中绘制以y为点，x和z为向量的3d。

Question

I want to plot 3D figure in R where I have y has fixed point and x and z are vectors. For example:

x=[1,2,4,8,16,32,64]
y=0
z=[100,200,300,400,500,600,700]

x=[1,2,4,8,16,32,64]
y=1
z=[...] // 7 points

and so on till y = 10

I tried to use wireframe where y = 1, and I always have error like that:

Error in eval(substitute(groups), data, environment(formula)) : 
  numeric 'envir' arg not of length one

Can anyone helps me to get that data plotted?

Answer 1

y must equal 1 for all values of x and z to plot in 3D. And it must be in matrix form.

> x <- c(1,2,4,8,16,32,64)
> y <- rep(1, 7)
> z <- c(100,200,300,400,500,600,700)
> d <- matrix(c(x, y, z), 7, 3)
> d
##      [,1] [,2] [,3]
## [1,]    1    1  100
## [2,]    2    1  200
## [3,]    4    1  300
## [4,]    8    1  400
## [5,]   16    1  500
## [6,]   32    1  600
## [7,]   64    1  700
