similar to: Adding points to a wireframe with conditioning variable

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

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 all, I’m trying to add some data points to a wireframe. X an Y axis are independent variables, Z axis is predicted probability. I’d like to add the original data points on which the predicted probabilities are based to the wireframe. I’ve followed some of the previous post on this but get stuck : ## first part yields the wireframe## setwd("C:/Temp") rnp <-

Hi, I'm trying to follow the suggestions given by Deepayan Sarkar in this message: http://tolstoy.newcastle.edu.au/R/help/05/11/16135.html to plot 3-D points on a wireframe plot. The problem is that I keep getting a partly formed plot- with the colored lattice visible but no axis labels or additional points- with the error message "error using packet 1, 'x' and 'units'

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))

Hi, I want to draw a figure similar to http://dsarkar.fhcrc.org/lattice/book/images/Figure_13_07_stdBW.png from http://lmdvr.r-forge.r-project.org/figures/figures.html (figure 13.7) . However instead of using a contour plot as a panel for the wireframe I want to use a levelplot. Can somebody help me with this? Thanks in advance for any help, Kind regards, Anton Bossenbroek

Hello, The following code produces a quadrilateral: q<-matrix(c(1,3,1,2,3,1,2,4,2,1,4,2),nrow=4,byrow=T) qc<-xyz.coords(q) wireframe(z~y*x,qc) I have 2 questions 1) How can i remove the bounding box i.e the cube encompassing the quadrilateral? 2) Is there any function to get the 2D coordinates of the quadrilateral actually used in the final plot ? I could manually

How can I eliminate the border drawn by default around a wireframe plot? I've tried using border=NA and box=FALSE to no avail. Scott Waichler Pacific Northwest National Laboratory scott.waichler at pnl.gov

Hello R-classicist won't like the following question due to there's no minimal reproducible example and the question was posted already. Anyway I'm not able understand this rather complicated version of "add points to wireframe". what I have is matrix 3x2000 with a dem<-(x,y,z, coordinates) (not provided). with follwing code I want to produce the wireframe and add some

Hello, hopefully simple question, but I cannot find the answer. I need to change the color from the standard default. Still want the scaled colors, but need different colors for different graphs. Code is: wireframe(z ~ y*x, mat.df, drape = TRUE, zlab = list("Water mass error (%)",rot=92), zlim=c(-50,180), xlab = list("Resistance error

A quick question. I'm trying to plot a surface from a fitted model along with the original points, as in the following example: df<-data.frame(expand.grid(100*runif(1:100), 100*runif(1:100))) df$Var3<-rnorm(length(df$Var1), mean=df$Var1*df$Var2, sd=10) my.lm<-lm(Var3 ~ Var1*Var2, data=df) my.fun<-function(x,y) predict(my.lm, data.frame(Var1=x, Var2=y),

Hello, I would like to plot a wireframe of a function which is defined on the unit square using the lattice library (for trellis-like plots). The plot contains z-values of about 100 (only in the neighborhood of zero) although most of the z-values are in the range of -let's say- 0 to 10. If I evaluate this function on an equidistant grid of 25 points on the unit square the plot quality is not

I am working on plotting a response surface using wireframe(). The default style/orientation is z | | y | \ | \ | \ | \ | \ | \ | \ | \|________________x 0 Now what I want the orientation of axes is: z | | | |

Hello List, I have some plots with the wireframe() function, and I'd like to display them in a single jpeg file. I know that par(mfrow=c(x,y)) will divide my display window in x rows and y columns, and although this works with plot(), it looks like it's not working with wireframe. here's my code: library(lattice) library(Cairo) CairoJPEG("wiley-rank.jpeg", width=960,

I need grayscale formatting for a wireframe. The only col.regions that I can find are color palettes are all colored: rainbow(n, s = 1, v = 1, start = 0, end = max(1,n - 1)/n, gamma = 1, alpha = 1) heat.colors(n, alpha = 1) terrain.colors(n, alpha = 1) topo.colors(n, alpha = 1) cm.colors(n, alpha = 1) The code follows: X11() library(lattice) par(family="serif", cex=1.2)

Hi R-helpers I would like to plot some planes which are perpendicular to the x-y plane, such as x=y. Is there a way to do this in wireframe? I realize that I am not plotting a function of x, y since there are infinite number of z's that satisfy the above relation.... Hmm... Somewhat related, I would also like to plot a line in 3 d space... Finally, if you are feeling really brave, I

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

Dear List, I am using the wireframe function in the lattice package, and I am wondering if it is possible to invert the default axes orientation for x and y axes... what parameter should I look for? Best regards, Simone Gabbriellini

Dear R Users, I am trying to plot a matrix (a Digital Elevation Model) using wireframe [lattice] and color that matrix based on a separate/independent matrix of the same resolution (both have the same number of rows and columns) as the DEM. More specifically I would like to plot a DEM using wireframe and color each cell/tile based on interpolated surface temperature measurements. Within 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.
