I do the folloowing in order to get 3D Plot:
y<-1:(point/2)
x<-20:30
z<-r[1:(point/2)]
persp(x,y,z,theta = 135, phi = 30, col = "green3", scale = FALSE,
ltheta = -120, shade = 0.75,
border = 1)
y:
[1] 1 2 3 4 5
x:
[1] 20 21 22 23 24 25
z:
[1] 4811.000000 3.593025 6.968666 4.908174 5.332700
but i always get the error message Error in persp.default(x, y, z, theta =
135, phi = 30, col = "green3", :invalid 'z' argument
How may I solve the issue?
