Hi R users and experts, I am interested in learning more about the use of 3D plots. Specifically, I want to add points and lines to a surface plot. And get the axes and labels plotted also. Here is what I have tried with an example data set : library(rgl) vol2 <- 2*volcano # Exaggerate the relief library(reshape) mvol2 <- melt(vol2) str(mvol2) # First, persp and persp3d plots do not succeed

Hello, Please could someone advise if it's possible to save the graphical output from the surface3d() function? I have tried the dev.copy() function to save as a pdf but an error message says I cannot copy from the null device.

Hi R users, Does anyone know how to change the size of 3d charts? I'm using surface3d in rgl package, opening a new window each time to display the chart. I want it so that the chart fills the whole window, because when I output it to png, I don't want all the white space around the chart (right now, i'm getting this white "border" around the chart because the chart is

Thanks to Edzer and Roger, I can now plot with increased font sizes. However, jpeg still does not reproduce these, nor does it show up in high quality. What I would like to do is produce some highresolution jpegs. Any help would be appreciated Thanx Herry R2.4 on Mandriva 10.2 linux.

Hi List, I have recently upgraded to opensuse10.2 and R 2.5 (compiled from source). Now, whenever I use plot the y-axis and labels are black blotches while x-axis and labels are fine. Using demo(graphics) this occurs with plot/boxplot/hist/pairs/coplot but not in the pie graphs and in the "The level of Interest in R" plot, which uses axis to define the y-axis. I presume this has to

Hi, I want to fit a kernel density estimator by bkde of library KernSmooth. I need only the density value at the point 0. I do not understand the following behaviour: > q <- rnorm(100) > bkq <- bkde(q, bandwidth=0.11, gridsize=1, range.x=c(0,0)) Error in 0:L : NA/NaN argument > bkq <- bkde(q, bandwidth=0.11, gridsize=1, range.x=c(-1,1)) > bkq $x [1] -1 $y [1] NA > bkq

Is it possible to call the super class''s version of a function from a subclass? SuperClass = Class.create(); SuperClass.prototype = { initialize: function(){ this.varA = ''''; this.varB = ''''; } } SubClass = Class.create(); SubClass.prototype = (new SuperClass()).extend({ initialize: function(somevar) { this.somevar = somevar; }

Hi all! I'm very new to R, and I'm having trouble figuring out how to go from a file of points that I have to a 3d surface plot of the data. I typically have something like this: X Y Z 0.005 0.023 34.45 0.0035 0.63 28.48 . I've tried looking at the persp and wireframe packages, and the rgl package, but I can't seem to figure out how to

Hi List, when loading library(rgl) I get error "RGL: GLX extension missing on server". I have Mesa and xgl installed, but xgl info sais its an highly experimental code. Does this mean I shouldn't bother for a while with opengl or are there alternatives?

Dear list, I am having troubles increasing the fontize when plotting a variogram{gstat} and its model (vgm) with plot and using jpeg(). Also the resolution in the jpeg call does not work. I am using R2.4 on Mandriva 10.2 linux. I can change fontsize with cex.axis in a normal plot, so I presume it has to do with plotting the variogram model. Any help on how to increase the font size and

Hi all, I have a data frame called "rst", see below: ------------------------------------------------------------------------------------------ # This is a paste able example # In case you don't have "KernSmooth" package installed, please uncomment below line. # install.packages("KernSmooth") library(KernSmooth) rst <- data.frame(hsp = rnorm(23), dal =

Thank you for your reply. I know the x in dpik() means the vector. But I don't know how to import into c() with a huge metadata (>1000). Following is my some try, and the h is: [1] 0.001180569, which seems to be feasible.

Ahhrg List, there was a hitch in the previous code. Updated and functional version follows after my initial question: I am trying to randomise a dataframe with mixed factors/numeric variables and return a new (randomised) dataframe with the same columns (as factors/numeric). simgap<-function(x) { ma<-max(x) mi<-min(x) Xout<-runif(length(x),min=mi,max=ma) return(Xout) }

Hi, I'm using rgl to generate a 3D surface plot and I'm struggling to get the lighting correct. Currently the surface gets plotted, but is very 'shiny'. On rotating the view, I get to see parts of the surface - but overall I don't see much detail because of the spotlight like lighting. I've played around with the specular, ambient and diffuse but I can't

Hi list, I am trying to print a rgl scene. I can do this with rgl.snapshot("test.pnt",fmt="png"), but rgl.postscript("test.pdf",fmt="pdf") does crash R and returns to the linux shell after extented time period. I am running R 2.4.0 on i686 linux mandrake 10.2. Do I need any other R external program to make this work? Thanks Herry Dr Alexander Herr -

I'm working with a large dataset - large enough that when I do a scatter plot the points all blur together, so I want to plot their density by color - a heat map or something like that. I've used smoothScatter for tasks like this, but the problem is that my current dataset really only looks good on a log-log scale. When I do the following command smoothScatter( data,

Dear All, I've tried to sum columns -- different species of flowers, fruits plus twigs -- with NAs to get litterfall/trap, and then after use litterfall to calculate production (litterfall (grams)/ hectare/ day. But R 'sees' litterfall/trap as a string. My question: How to use basic mathematical functions to deal with NAs in data management. Example (as you can note I have many

Dear R-experts, Using persp3d(), I plotted a 3d surface. I would like to colour this surface based on the result values (dependent variable) grouped in, say, three to five different ranges. Later, I would also like to paint the same surface based on the range-values of one of the independent variables. Please help. Thank you. Regards, Suresh -- View this message in context:

Hi All- I would like to create a 3d topographic map using lat/lon and z(height). I have been scouring the R help pages and have not located the package I am looking for. Does anyone have a suggestion of package that will work for this? thanks- sherri
