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

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

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

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.

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))

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

How can I control de "wrap-around" color behaviour in the persp function ? I am using something like : persp(bb[1:100,2:97], col= rainbow(8,start=0.1, end=0.8))) Depending on the rainbow length value I get several "wrap-around" blocks of the selected color range...something that I wanted to avoid... My idea is to use the color in order to make a separation from a certain

I have an issue when making a wireframe plot. I can't find any way to change the number of ticks on the labels. I try to set it in the code below with z.ticks=1, but that doesn't work. Is there anything that works? (Note. I need to use wireframe. persp is out of the question since I want mathematics in the axis labels). Here is some sample code: library(lattice) x <-

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

Hi everybody, I'm working with wireframe (and persp) functions, and I'm not able to set the margins between the 3d plot and the R window... It should be easy, innit?, but I can't find out which parameters I have to change... Any help?

Dear R-helpers Can anyone direct me to a method for plotting what you might call a partial wireframe plot? I have two explanatory variables in a dataset which give me a significant interaction term when I fit a model. The two variables are correlated with each other to a moderate degree, and if I plot the predicted values from the model as a surface in a 3D wireframe plot there are some

Hi R help, What is the best way to plots surfaces in 3 dimensions? I also have the following availability problem with "plot3d" and "scatterplot3d", and "wireframe": install.packages("scatterplot3d") Warning: unable to access index for repository http://cran.ch.r-project.org/bin/macosx/leopard/contrib/2.10 Warning message: In getDependencies(pkgs,

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

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)

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 =

Hello Everyone, I am using R ver. 2.10.1 (2009-12-14). I installed lattice today via install.packages. I am doing this minimal example: M = read.csv("/path/to/csv") cloud(x ~ y * z, data = M) this correctly gives me a scatterplot of the csv data which has 3 columns. Every column contains 1800 numeric 0 < values < 1300 when I want to plot the corresponding wireframe via

Dear expeRts, I would like to add two points to a wireframe plot. The points have (x,y,z) coordinates where z is determined to be on the wireframe [same z-value]. Now something strange happens. One point is perfectly plotted, the other isn't shown at all. It only appears if I move it upwards in z-direction by adding a positive number. So somehow it disappears in the wireframe-surface

Hello, I try to increase the distance between tick labels and ticks in a lattice wireframe plot. Here's a minimal example: ## Minimal example x <- y <- z <- c(1,2,3) df <- data.frame(x, y, z) wireframe(z ~ x*y, df, scales = list(arrows = FALSE, col = "black", font = 1, tck=0.6)) I tried the axis.components option

Hi, I am using function wireframe from package lattice to draw a 3D surface. I would like to add a few points on the surface. I read in a post from Deepayan Sarkar that "To do this in a wireframe plot you would probably use the panel function panel.3dscatter". Does someone have an example? When calling panel.3dscatter with only x, y and z arguments I get "argument
