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 exam...

Hello I was wondering if anyone has been able to change the pch value for points in 3dplot()? I am able to change point colors just not symbol types. I have included a portion of my code below. I realize this won't work outside of my script, but thought, maybe there is something obvious that I am doing wrong. Also is it possible to utilize the interactive feature of 3dplot in a...

I think it is an easy question but i haven´t found a solution since I am r beginner. I did this plot3d(PCoA, type="p", col=rainbow(1000),size=5) text3d(PCoA, text=Nam) How can I save it including the labels to a jpg-file? Thanks in advance.

I am trying to dp a 3d plot. I tried persp but my data is not a matrix. the 3dplot function returns this error, (list) object cannot be coerced to 'double' heres my code, td<-read.csv("td.csv", header=TRUE) price<-read.csv("price.csv", header=TRUE) contractdate<-read.csv("contractdate.csv", header=TRUE) library(rgl) plot3d(td,con...
