persp(): add second plane
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.

What does persp() return?
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

3d Map with bars
Apologies in advance for the question. I am trying to draw a map of the US as a surface plot so that I would be able to drop bars on the different states (something like Uwe Ligges' scatterplot3d example 4). I am not sure where to start looking for such a beast. If anyone has any pointers, ideas, I will be grateful. TIA, Partha

persp(): add second plane (second, long question)
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

plotting intersecting planes
Hi all In two days, I am giving a small, informal workshop in our Department about using R. Initially, it was just for statistician, but surprisingly (to me anyhow) many mathematicians are also coming who have a MATLAB background. They are coming at the Workshop from a teaching perspective. They are considering using R to avoid licensing issues with MATLAB. One thing they were hoping me to

Draw level lines on the surface of a bivariate function
Hello, Is it possible to draw level lines on the surface of a bivariate function? In the following example, to draw surface and levels lines for a multivariate normal law, I use persp, trans3d, contourLines and lines, but if the lines are correctly drawn, some parts of them are, of course, visible even if they are drawn on a non visible "face". Any suggestion to avoid this problem

persp plot + plotting grid lines
Dear all; Does anyone know how to add grid lines to a persp plot? I've tried using lines(trans3d..) but the lines of course are superimposed into the actual 3d surface and what I need is something like the plot shown in the following link: http://thermal.gg.utah.edu/tutorials/matlab/matlab_tutorial.html I'll appreciate any ideas Thanks PM

3d scatter plot with drop line
This is a follow up to my question from yesterday. I want to do in R what is called a "3d scatter plot with drop lines" in S-PLUS. Basically, it's a 3dscatterplot with lines connecting the x-y grid to the z points. The lines give a better perspective on the shape of the data surface. How to? Joel Bremson UC Davis Statistics

Adding 3D points
I would like to add individual points and lines to a persp() plot that I generated with the geoR package. It is a kriged surface map of a field plot and I'd like to overlay my sampling points on it but am having some trouble. I loaded the scatterplot3d package, but I can't seem to use the add parameter with it. Any suggestions?

Plot a sphere
Hi, I'm new to R (and math ;) Would somebody please be so kind as to direct me in plotting a 3D sphere? I tried something in the lines of: #### y <- x <- seq(-pi, pi, length=pi*10) f <- function(x,y) { z <- sqrt(pi - x^2 - y^2) #z[is.na(z)] <- 0 z } z <- outer(x, y, f) persp(x, y, z, theta = 120, phi = 30) #### I've also tried: .... make.surface.grid(...) ..

persp( ) Question

lines on persp plot - proper depth ordering
Hello R-help! I am trying to draw series of lines in 3d, and I am not sure how to get the depth set up properly - lines that are in front of other lines appear to be behind and vice versa. I've been doing this by first generating an empty persp plot, then adding lines via the data into trans3d followed by lines (this is probably a bad approach, but it was the first one I could get working).

persp and lines()
R-sters: I'm interested in keeping data plotted in persp to preserve the wireframe look, I'd just like to change one of the lines drawn (in either the x or y direction) into a different color so that it stands out. Or is there some way to add a line (say, via lines(), or abline()) to a persp() plot at the designated x or y that would follow the z surface contour? I could add a line

persp(), scatterplot3d(), "..." argument
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,

Re : how to plot select points in preexisting persp plot
Hello, I am trying to plot selected data points to a preexisting persp plot that satisfies a condition. I used the following statement - text(coords[,1], coords[,2], names(act[which(act > 8.75)]), cex=0.7) But I get all the points labeled, instead of the points that satisfy the condition specified. Is there any way to plot only the points I want? Also can this be done using

Arrow and text on a 3d plot
I am currently working on surface plots (with R 2.0.1) and I want to improve the aspect of them. Having a typical 'cow-boy hat' surface [source: Spector (1994), p. 206]: pts <- seq(from = -8, to = 8, length = 50) cow <- function(x, y) { z <- sqrt(x^2+y^2) sin(z)/z } out <- outer(pts, pts, cow) sur <- persp(x=pts, y=pts, z=out, theta=45, phi=30) What I exactly wanted is:

Adding Text to a persp plot using specific coordinates
Hi folks, I'm experiencing some hassle to add some text on a persp plot... Here is the code to generate the persp plot: x <- seq(-1.95, 1.95, length = 30) y <- seq(-1.95, 1.95, length = 30) z <- outer(x, y, function(a,b) a*b^2) persp(x, y, z,xlim=c(-2,2),ylim=c(-2,2),zlim=c(-8,8), phi=30, theta=-30,nticks=8,ticktype="detailed") I've tried the text() function :

Plot bivariate density with densities margins
Dear R users, I would like to plot the bivariate density surface with its marginal densities on the sides of the 3D box, just like in the picture I attach. I tried to found information about how to do it but did not find anything. Does anyone know how to do it? Thanks in advance, Eduardo.
