[R] help with scatterplot3d
Hello, I am having a bit of trouble with scatterplot3d(). I was able to plot a 3d cloud of points using the following code: my.3dplot-scatterplot3d(my.coords, pch=19, zlim=c(0,1), scale.y=0.5, angle=30, box=FALSE) where my.coords is a data frame that contains x, y, and z coordinates for grid points whose elevation we sampled. The problem occurs when I try to add points using points3d. I tried to follow the code in the examples of the package pdf. First, I tried the following code to add all of the points that I wanted: my.3dplot$points3d(seq(400,600,0.19), seq(600,400,0.295), seq(800,500,0.24), seq(1000,1400,0.22), seq(1200,600,0.24), seq(1200,1500,0.28), seq(1300,1400,0.205), seq(1700,500,0.26), seq(1700,600,0.21), seq(1900,1400,0.255), seq(2300,1400,0.275), seq(2600,1300,0.225), seq(2700,400,0.235), seq(2700,1300,0.265), seq(3100,1000,0.135), col=blue, type=h, pch=16) and got the following error: Error in seq.default(600, 400, 0.295) : wrong sign in 'by' argument So I just tried to add the first point using the following code: my.3dplot$points3d(seq(400,600,0.19), col=blue, type=h, pch=16) and got the following error message: Error in xyz.coords(x, y, z) : 'x', 'y' and 'z' lengths differ. Does anyone know how I can use this function in the scatterplot3d package? Thanks so much! Ryan ~~ Ryan D.
