...f 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...

In my case the different colored and sized points represent different clusters from the results of the Partitioning Around Mediods (pam) clustering function (from library cluster). I have used thi...

Hi, I am trying to compare two 3D plots. For that, I am trying to use the "pch" parameter in the "points3d" function, but it is not working. Is it implemented? Any suggestion? Here goes a reproducible code. I wanted the second plot having different symbols for the points. x <- rbind(matrix(rnorm(100, sd = 0.3), ncol = 2), matrix(rnorm(100, mean = 1, sd = 0.3), ncol = 2),...

...different sets of arguments, I can't just use "..." ; I did write some code a while ago that would look at formals() to dissect out arguments that should be passed to the different functions, but it seemed overly complex. The particular case I have now is a little simpler. foo2 (points3d) and foo3 (spheres3d) are both functions from the rgl package that pass arguments such as color, alpha, etc. along to an rgl.material() command with lots of possible arguments. (The function may also call segments3d or lines3d, but these all have the same arguments as points3d.) However, to change...

Hi all, I just started using the rgl package in R, and I need to know how I connect the dots I created. A simple line from one co?rdinate (x0,y0,z0) to another (x1,y1,z1) will do. I tried using the code rgl.lines, but it doesn't accept lines that don't stem from O (0,0,0). Please help! Thanks! -- View this message in context:

...I am not able to add " species scores " from RDA results in 3D plot like i can in 2D plot. With the code i used , i get errors like ; ERROR dans t$sites : $ operator is invalid for atomic vectors, Erreur dans match.arg (display, items) : 'arg' should be one of ?xyz.convert?, ?points3d?, ?plane3d?, ?box3d?, ?points?, ?arrows? I saw that I can use other functions, but it is impossible to extract the 3D scores ( and add species to 3d plot ), Other fonctions works but, add elements in a 2D space. How can I add the "species scores" (sites and arrows are added correctly)...

Thank you for your replies so far. Sorry for bothering you again, but I'm still not able to get what I need as I don't understand all parts of the replies (just using R for easy things....). Is there a code for plane3d() like some of you sent me for points3d()? I was not able to get that out of the scatterplot3d package... What I can do is to get the x,y and z-range for the xlim,ylim and zlim so that the two planes would fit the box (x and y values are the same for both (1x6vectors)). And I'm able to store the z-values in two different matrices (...

Hi all, I've been using the scatterplot3d function (from the scatterplot3d library) to create 3D plots. I was wondering whether there is anyway to group the points according to a particular group variable. For example I used the plot function as plot( factor( <GROUPINGVAR> ) , <PLOTVARS> ) to organise the results in a according to the grouping variable. I was wondering

...ally use R for simple 2D graphs so now I cannot solve the following problem (which I suppose very simple too). I'm using scatterplot3d. I want to add dotted lines parallel to the 3 axes, in order to create a sort of cage in the 3D box (so to represent subdomains in my dataspace). I saw that points3d can be used to draw points or lines to the existing plot but actually I'm able only to draw points (I grabbed an example from the web) Could anyone post a line of code with an example?

...the onion package?? I want to plot points with different colors on the same 3D plot.? Perhaps I can do this without adding points but somehow directing the 'h' parameter to give different color to points based on a factor I assign to them? FYI, I can do this using using scatterplot3d() and points3d(), but these plots lack perspective and hence it is hard to sense depth without the use of color. Thanks, Brad
