similar to: persp plot

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

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 :

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 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).

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 all, I have a (hopefully quick) question. I've got a fascinating set of fitted surfaces in three dimensions corresponding to local linear multiple regressions. I'd like to add rugs to the X and Y axes (corresponding to my independent variables) in order to get a sense for how many data points I'm working with to graph various portions of the surfaces. The trouble is, I can't

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

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,

R'istas: I am trying to plot a marginal distribution on the plane behind a persp() plot. My existing code is: library(MASS) X <- mvrnorm(1000,mu=c(0,0),Sigma=matrix(c(1,0,0,1),2)) X.kde <- kde2d(X[,1],X[,2],n=25) # X.kde is list: $x 1*n, $y 1*n, $z n*n persp(X.kde,phi=30,theta=60,xlab="x_b",ylab="x_a",zlab="f") ->res Any suggestions are very

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.

I have successfully fitted the model loess.fit1 <- loess(response ~ X*Y) and plotted it in 3D using X.grid <- seq(0,10,length=100) Y.grid <- seq(0,1000,length=100) pred.loess1 <- predict(loess.fit1, expand.grid(x = X.grid, y = Y.grid)) persp(X.grid, Y.grid, pred.loess1, theta = 0, phi = 12) I would like to add a series of points along the fitted surface at X.grid =

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

Hi the manpage for persp() has a wonderful section where a the trans3d () function is used with points() and lines() to add red dots and a green sinusoid to the Mexican hat surface. Does anyone have a way to tell what distance a point is from the eye/ camera? Take the following line: lines (trans3d(x, y=10, z= 6 + sin(x), pm = res), col = 3) Is there a function like trans3d() that returns

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 am a beginner R user. I have been able to make a 3D surface plot using 'persp'. The surface is made by a grid of lines emanating perpendicularly from each of the x and y axes at regular intervals. I can get rid of that grid by setting 'border=NA'. Can anyone suggest some ways to replace the grid with contour lines, to create a 3-dimensional contour map? Thanks

Hi the list, I write a short function to draw lines in 3D, showing then turning. At some point, I add "delais" to slow down the rotation. So two questions: 1) I try to find a library to draw animate lines in 3D but I did not find. That surprise me since it is very simple to do. Did I forget to look somewhere ? If it does not exists and I have to use my own function : 2) Is it

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?

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
