Hello, I am trying to get a surface plot of a data set that looks like the following, 1 2 5.6 5 9 2.4 9 8 9.8 ... to (60,000 rows down) From my homework, the persp function only works with evenly spaced data points with the z data beeing in a matrix. my data is not in that format. the wireframe fxn gives me an error, no applicable method for "wireframe" the

Hello Dear, I have a function, like z=f(x,y), and try a surface plot with this function. But, on the reference of "wireframe" requires data option, so I generated x and y, and computed z with them. But, still I have a problem to draw a surface plot. The code and errors are ################################################## mle_beta0=64.43707; mle_beta1=-24365.16; # generating for

It is a trivial matter to adjust the linewidth of the axes and plot line in a 2D plot: x <- 1:10; y <- 1:10; par(lwd=2); # axis (and others) linewidth plot(x,y,"l",lwd=6); # plot linewidth Is there anything comparable to this for persp or wireframe? I've tried a number of ways, and the framebox/axes seem to be linked to the linewidth used in generating the

Hi all, I've got two persp plots with Identical X and Y's, and I'd like to plot them on the same graph, so that it is obvious where one plot is above the other. I can't find any mention of this anywhere. Do I need to use wireframe? Any help is appreciated. Thanks, -- Ian Bentley M.Sc.

I am trying to graph two planes on the same graph using persp(). I can only get one plane to plot at a time. Can someone explain how I can graph two planes on the same graph using persp? I've looked throught the documentation, but cannot find any references to appending a persp plot. Thanks. Sincerely yours, Mark J. Lamias Statistical Consultant

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

Hello folks, i'm a R beginner and i want to put in a same plot both contour lines and persp plot. For example, fn<-function(x,y){sin(x)+2*y} #this looks like a corrugated tin roof x<-seq(from=1,to=100,by=1) #generates a list of x values to sample y<-seq(from=1,to=100,by=1) #generates a list of y values to sample z<-outer(x,y,FUN=fn) #applies the funct. across the combos of x

Hello R-sters, I'm trying to add several lines to a response surface that I've plotted using persp(). I've tried lines() using the "trans3d" function but I've been unsuccessful in getting it to work (R v2.0.1). Essentially, I'm trying to highlight one or more of the surface wireframe lines in a bolder (or different) color. Any tips from those of you who have some

Hello, I am plotting a 3D function using persp and I would like to use greek symbols in the axes labels. I have found examples like this one on the web: plot(0,0,xlab=expression(kappa[lambda]),ylab=substitute(paste(phi,"=",true,sigma),list(true=5))) this works well with plot but not with persp: with the command persp(M,theta = -20,phi =

I've created a perspective plot using 'persp' in the graphics package. I'd like to add a second plane of z values to the existing plot, but I cannot seem to do this using 'persp'. Is there an analogue to 'lines' or 'points' for perspectives? Corey. corey.bradshaw at cdu.edu.au

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.

Dear R experts, On explanation of persp() parameters the last item is: ...: additional graphical parameters (see `par'). However, setting the `tcl' parameter has no any effect. I guess that axes are added to persp() in somewhat freakish way, and have nothing in common with axis() function. I found the very useful trans3d() function in persp() help page, and I'd like to use it

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

Hi. I'm a student at Simon Fraser University in British Columbia, Canada. I can't for the life of me figure out how to plot a 3D surface (A 3D response surface to be more specific) in R. I found your email address on a web board, and saw someone mention wireframe(), but using the help in R yielded no results. Any suggestions? Thanks. Dean Vrecko

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

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 draw a surface corresponding to bivariate density of independent variables (rho=0) using persp(). Then I add a contour line (i.e., circle in my case) at a particular density. Below is a minimal example of what I have so far. # Bivariate density dnorm2d <- function(x, y, rho = 0) { xoy = (x^2 - 2 * rho * x * y + y^2)/(2 * (1 - rho^2)) density = exp(-xoy)/(2 * pi * sqrt(1 - rho^2))

Dear R-users, I would like to place two 3D plots side-by-side in a rgl-setting. It would nice to have something like "par(mfrow=c(1,2))" for basic plots, or an array framework for wireframe(lattice) (see example below). I only managed to overlap two persp3d plots. My final idea would be to animate both surfaces using play3d(rgl). Thanks in advance for any help. Best, Carlo Giovanni

I have what is probably a noob question, but.... I am trying to create a 3d plot to illustrate the range of values for the following simple function: A = B*(C/D) B, C, and D are independent variables whose range are equal (e.g. 1 to 3 inclusive) I figure it's not possible to map the surface of A on the 3d space defined by B, C and D but I would like to create a surface defined by the

Dear all, I would like to put two perspective plots into one plot. The help page for ?persp shows how one can add points and lines but not another perspective plot. data(volcano) z <- 2 * volcano # Exaggerate the relief x <- 10 * (1:nrow(z)) # 10 meter spacing (S to N) y <- 10 * (1:ncol(z)) # 10 meter spacing (E to W) ## Don't draw the grid lines : border = NA persp(x,
