Hi, I am trying to specify four ticks (at 0,1,2,3 for the y axis) in a persp plot but the defaults overrule my specification and I obtain seven of them. Is it possible to gain full control over them in such a plot? Here is my code: matlines=matrix(c(1:7,3:9,3:9,2:8),nrow=7,ncol=4)

Hi R-listers, I am having trouble with persp plotting and I hope some knowledgeable person can help me. I have searched the help files to no avail. I am sure there is a way of achieving this simple task. I thought in par maybe but that seems not to work for 3d plots. Maybe I have missed something. I read in ?persp that it expects increasing values for both my x and y axes, and a matrix

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).

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 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 R-users, I'd like to plot a three-dimensional surface and at the meantime I'm using an array. I would like to have the values of my first matrix in the heights of the plot and the colors of the single facet taking into account the second matrix. I hope that the next code will help all of you to understand better my issue, Thanks in advance, Giancarlo ############################ ##

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

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 <-

Hi All, I'm using 'tck' option to *reduce* the length of tick marks but it is not working, can anyone please tell me where I'm going wrong... require(graphics) require(grDevices) x <- seq(-10, 10, length= 30) y <- x f <- function(x,y) { r <- sqrt(x^2+y^2); 10 * sin(r)/r } z <- outer(x, y, f) z[is.na(z)] <- 1 # 'bg' works but 'tck' is not showing

Dear All, I am very new to R projects.May be i am wrong in some steps.I have given the code which i tried for drawing 3d surface using persp.I need to label the axes with scales z <- array(topnew2$V2, dim=c(600,2)) x <- 10 * (1:nrow(z)) y <- (1:ncol(z)) persp(x, y, z, theta = 30, phi = 30, expand = 0.5, col = "lightblue", xlab ="fluidlevel", ylab

Hello all, I am trying to use computer modern fonts in my r grahics. I tried to do, as described here: http://www.stat.auckland.ac.nz/~paul/R/CM/CMR.html but unfortunately, it does not work. First of all I downloaded the cm-lgc package and the AFM and PFB-files from the page and put them in my R working directory, so far, so good. Then I tried to run the following code: > sn <-

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

Dear R list, I want to plot the yield curve in a 3D graph: the x-axis refers to time; the y-axis refers to the maturities and the z-axis are the yields. The following code works fine: persp(y, x, as.matrix(ypper), xlab="Last 50 periods", ylab="Maturities (months)",zlab="Yields", zlim=c(3,6),theta=130, phi=15, col="Seagreen", box=T,

Thank you for your replies so far. Sorry for bothering you again, but I'm still not able to get what I need as I don't understand all parts of the replies (just using R for easy things....). Is there a code for plane3d() like some of you sent me for points3d()? I was not able to get that out of the scatterplot3d package... What I can do is to get the x,y and z-range for the xlim,ylim and

All, This was posted earlier but may have got lost in another thread. Can someone tell me how to independently alter the fontsize and position of labels on a persp plot?? I've tried using titles() and axes() but they seem to only apply to the standard plot() and contour plots (contour() and filled.contour(). Commands like text() seem only to add to the margin of the plot rather than

Hi, I am trying to create a perspective plot with Time on the x-axis, Underlying Price on the y-axis, and Option Price on the z-axis. But I don't like the way my x-axis is setup. Right now, Time is this sequence. Time = seq(from = 1/52, to = 1, by=1/52) That results in the x-axis going from 0 at the back, to 1 near the foreground corner.(If that makes any sense) I want to do the

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 folks~ As yet I've been unable to determine how to expand the distance between the tick marks and tick labels in perspective plots. None of the 'par' setting appear to be applicable to this (including mfg), and placing multiple plots per page results in a bit obscurity, with the tick values overlapping either the tick marks or the axes themselves. The code:

Hi, I have been using the persp() function to plot species response surfaces based on GAMs (using package mgcv). Everything works fine, except that I have a slight problem when it comes to producing a figure with multiple (4 - 6) persp() plots on it. The axis labels remain the same size, no matter how large or small the plot is, causing some overlap when the multiplot figure is produced. Is
