similar to: White lines on persp plots in pdf format

persp(outer(1:5, 1:5), shade=0.1) looks nice on the screen, but postscript() persp(outer(1:5, 1:5), shade=0.1) dev.off() gives an all black surface. same when using the pdf() device. has already been like that in 1.4.0. .f --please do not edit the information below-- Version: platform = i686-pc-linux-gnu arch = i686 os = linux-gnu system = i686, linux-gnu status = Under development

I am having some trouble getting the persp() package to change the x and y axis on a 3d plot. It defaults to the [0,1] interval and when I try to change it I get errors. Example: This works: ------------ D <- c(1,2,3,4,5,6,7,8,9,10) M <- c(11,12,13,14,15,16,17,18,19,20) DM <- cbind(D,M) persp(DM, theta = 40, phi = 30, expand = 0.5, col = "lightblue", ltheta = 120,

Dear Devels, I'm not sure if I'm going the right way by mailing to this list. I have two suggestions regarding the persp function from the graphics package: 1. In the documentation of the persp function, it is said, that the "col" argument will ignore transparent colors. However, this is not true, if you use strings as color code - at least it works with HEX-code (eg. :

I just changed machines and, at first, could not get LyX 1.4.3-4 to even load. I tried 1.5 which loaded nicely but would not give me PDF output. Removed 1.5 tried using 1.4.3-5.exe. Result : On loading LyX : lyx: Disabling socket cont class std::basic_string<char struct std: char::char_traits ... Removed and installed from LyXWin143Complete-2-9.exe. Loads okay but no PDF generation. My

Dear All, I have been trying to to do this for a few days now. I can generate persp plot OK and can generate it in colour using the command persp(x,y,z,col=terrain.colors(20)) However, I was wondering if it is possible to shade the 3d surface like a contour plot. i.e. black for large z, white for small z, say Thanks in advance Colin

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,

I have this data set that both x & y are ordered vectors of length 600 & 700 respectively; z is a 600 by 700 matrix whose entry z[i,j] is either a missing value (indicated by 'NaN') or a real number between 0 and 1. The contour function contour(x,y,z) gives me a blank picture. I guess the reason is that most of z-entries are missing, only less than 1% are non missing.

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

This problem has bugged me for several years now, and our own IT staff has tried a few things, but then never cared enough to persist fixing it. It *is* a bug in evince, the standard pdf viewer on Fedora and IIUC also quite few other Linux distributions, and *not* a bug in R; hence I am asking for help/hints here. A very simple example:

Hello, I would like to plot two superposed surfaces (original data, and smoothed models). Basically, I would like to create a usual persp plot with box, and then superpose a second surface (without box and axes) on the top plane of the box defined by the first graph. I don't know if it is clear :-( Is it possible to draw such a second surface in an existing persp plot in R? Another (related)

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 :

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

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, I have a problem in drawing a 3d graphic. I simplified the program to show you the problem. I have a text file with hundreds of entries in 3 columns. I scaned these columns with matrix(scan). Then, I transformed some datas. Now I have the datas in h,x,y. I created a new matrix to use persp . But I got an error. The reason is probably the same length of x,y,z. But what can I do the draw

Hi Martin Probably not the answer you're looking for but on the latest Fedora 39 (workstation edition) both locally, and on a freshly installed VM (with just R-core installed), all fonts render correctly for me in evince. $ evince --version GNOME Document Viewer 45.0 $ R --version R version 4.3.3 (2024-02-29) -- "Angel Food Cake" Copyright (C) 2024 The R Foundation for Statistical

someone sent in a question earlier about doing something in 3D so i took a stab at it purely for educational purposes ( i'm not even sure that I understood the question actually ). Unfortunately, persp gives me an error that I don't understand because it says "object y not found". I'm sending y in as a parameter to persp similar to what ?persp shows in one of oits examples

Hi, and thanks in advance for any assistance, I'm new to R and to this mailing list, and am having trouble with the * persp()* function. I've got a matrix (z) of values for various combinations of x and y, each of which is a set of (0, 5, 10, 15, 20). But when I try * persp(x,y,z)*, I get an "*invalid z argument*" error, and when I try simply *persp(z)*, R returns an

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
