Hello list. I very often need 3d scatterplots, and use scatterplot3D quite a lot. I am trying to modify persp() to plot scatterplots, and make use of the theta and phi arguments that persp() offers. I am having some difficulty passing the correct arguments to persp(). Here is my function so far. Much of it is copied from the persp() manpage. points3d <- function(x,y,z,

Hello, I have three x-y plots whose interesting data occurs at the same time. When I place them in the same plot, they tend to obscure each other. I was hoping to use persp or scatterplot3d to plot them 3-dimensionally, so that the plot is visually useful. My data is simple: x, for all three data sets, is a set of 885 ISOdates, where x <- x0 + seq(1, 885). y is the value of "io",

I have been making simple functions to display regressions in a new package called "rockchalk". For 3d illustrations, my functions use persp, and I've grown to like working with it. As an example of the kind of things I like to do, you might consult my lecture on multicollinearity, which is by far the most detailed illustration I've prepared.

Hello I am trying to draw a basic black and white map of two European countries. After searching some key words in google and reading many pages I arrived to the conclusion that persp() could be used to draw that map. I have prepared three small example files, which are supposed to be the files required for running that function. xvector is a vector with the longitudes yvector is a vector with

I want to plot some 3D points on top of the grid produced by persp(). On 2/22/01, Paul Murrell <paul at stat.auckland.ac.nz> wrote in R-help: > In S-Plus, persp() returns a value that can be used to transform 3D > locations to 2D, but this sort of thing is not (yet) available in R. But persp() does return something (in R-1.5.1): a 4x4 matrix which in the C code is called the

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

Dear Listers, I would be interested in representing a trend surface including an interaction term z = f(x,y,x.y) - eg the type of chart obtained with persp() or wireframe(), then adding datapoints as a cloud, ideally with dots which are under the surface in a color, and those who are above in another color. An other option would be to draw segments between the dots and the ground of the

Dear All, I am trying to visualize the surface of a bivariate kernel density estimate. I have a vector of bivariate observations(x,y), and a function which computes the kernel density estimate z corresponding to each observation. I cannot generate the (x,y) data in the ascending order needed by persp(x,y,z). I was wondering whether there is an R version of the S function interp. Would anybody

someone sent in a question earlier about doing something in 3D so i took a stab at it purely for educational purposes ( i'm not even sure that I understood the question actually ). Unfortunately, persp gives me an error that I don't understand because it says "object y not found". I'm sending y in as a parameter to persp similar to what ?persp shows in one of oits examples

I have a set of data in the form x1, y1, z1 x1, y2, z2 ... x1, yN, zN x2, y1, z(N+1) x2, y2, z(N+2) ... x2, yN, z(2N) ...and so on... xM, yN, val(M*N) I have been trying to figure out how to get R to use this data in a persp plot. So far the only thing that I can figure out to do is to break the data file into three different files. The first file contains the x-coordinate data: x1 x2

Hello, I have a problem in drawing a 3d graphic. I simplified the program to show you the problem. I have a text file with hundreds of entries in 3 columns. I scaned these columns with matrix(scan). Then, I transformed some datas. Now I have the datas in h,x,y. I created a new matrix to use persp . But I got an error. The reason is probably the same length of x,y,z. But what can I do the draw

Hi, I am doing my way on R, with much experimenting. So, I am trying to plot a 3d graphic ussing "persp" and entering a data set (attached) of UTM coordinates as x,y and a pH values as z. However when I try an error message comes out telling that increasing x and y values are expected. Jus ordering the first vector does not help, and, of course, order the first two independently

Dear all, Thank you for any help. I have a data.frame and would like to plot it in 3D. I have tried wireframe() and cloud(), I got scatterplot3d(xs) Error: could not find function "scatterplot3d" > wireframe(xs) Error in wireframe(xs) : no applicable method for "wireframe" > persp(x=x, y=y, z=xs) Error in persp.default(x = x, y = y, z = xs) : (list)

Hi, I would like to plot a matrix which comprises 3 columns. So first column should be the x-axis. Second the y-axis and the third one should be the z-axis. I know that I can plot such data using the scatterplot3d, but I would like to have a surface plot like you can do with wireframe and persp. But both, persp and wireframe, want to have x and y as descending data, at least persp. I am not sure

I have a large matrix and want to create a 3d surface of it. Suppose the matrix looks something like Matrix K: a<-c(1:1200) b<-c(rep(1:30,40)) c<-c(a+b^2) K<-data.frame(a,b,c) The vector values are not ordered (and repeat themselves as in b). Whenever I try commands like "persp" it wants ordered values. The only command that approximates what I

Dear R-users, is it possible to add a second plane to the persp()-plot? I couldn't find any hint on that in the news archive... I'm using R.1.4.1 for Windows.

Dear helplist members, I have been using 'wireframe()' to make 3d plots using the following call: wireframe (temp ~ xc2 * mc2, screen = list(z = 230, x = -70, y = 0), scales = list (arrows = FALSE)) and these three vectors: xc2 mc2 temp [1,] 0.1 0.04 0.049797615 [2,] 0.2 0.04 0.049161159 [3,] 0.3 0.04 0.048006702 [4,] 0.4 0.04 0.046208311 [5,] 0.5 0.04

DeaR list, I'm trying to represent some information via 3D plots. My data and session info are at the end of this message. So far, I have tried scatterplot3d (scatterplot3d), persp3d (rgl), persp (graphics) and scatter3d (Rmcdr) but any of them gave me what I'd like to have as final result (please see [1] for a similar 3D plot changing PF by ypred, pdn by h4 and pup by h11).
