Dear R users, I have two nonlinear equations, f1(x1,x2)=0 and f2(x1,x2)=0. I try to use optim command by minimize f1^2+f2^2 to find x1 and x2. I found the optimal solution changes when I change initial values. How to solve this? BTW, I also try to use grid searching. But I have no information on ranges of x1 and x2, respectively. Any suggestion to solve this question? Thanks, Kate

Hallo! ? I just want to make a 3D plot of a surface of a cone and want to plot some single points around. ? I tried wireframe but cannot find how to plot single points ? I tried scatterplot3d but there the surface is not simple to plot. And: How can I rotate the point of view by the z-axis ? I tried persp3d but how can I add some single points? ? Example: ? library(lattice) library(scatterplot3d)

Summary: We cannot connect multiple users from an win2K/tse box to a samba server using password server authentication . Details: We have samba 2.2.8a on Sun Solaris , connected with an w2k/tse . Samba has been configured to check user/password using an "password server" on the network ( Domain PDC ) . When the first user connect to the win2k/tse all network shares are ok . But when

Hello all, Is there any way to get each file from a website list and aggregate in a data frame? Otherwise I have to type 23 thousand web address into a long script like it: base1 <- read.table("site 1", sep=";", header=T, fileEncoding="windows-1252") base2 <- read.table("site 2", sep=";", header=T, fileEncoding="windows-1252") I

Hi [Samba]s This is a call for some generous people to try out the process of installation of a Samba printer on WinNT and WinNT Terminal Server Edition. I am working through Kurt Pfeifle's HOWTO on Printing and CUPS printing in Samba 3.0, and finding some issues with NT/TSE. It would be good if we had some confirmation or otherwise of these problems so that Kurt can update his HOWTO (this is

Hi all! I can't use the TSE licence server in Windows 2008 server. This Server is member of my Samba Domain. My TSE licence server is actived and my licences added, but when i want configure the TSE service and launch the Licence diagnostic the diagnostic failed. I think my problem is due to my Windows Server is not an Active Directory controller. What are the solutions : quit the

Hi, *Warning: R newb here. * I've got a 3D scatterplot ( http://www.fleetwoodswoodworks.com/scatterPlot.jpg) which I want to drape in color, with the draped plane corresponding to the mean z values on the plot (similar to: http://www.fleetwoodswoodworks.com/draped3Dscatterplot.jpg). Does anyone know what package will allow me to do this? I used * scatterplot3d()* for my first plot. I've

Dear All, I want to create a surface plot from the data. My data set is consists of x, y and z data. I plotted in very easy way by Excel worksheet as shown in the attached picture. I did some steps in R, but I cannot have the same plot as in Excel worksheet's figure. the R code is x <- c(-1,-0.75,-0.5,-0.25,0,0.25,0.5,0.75,1) y<- c(-1,-0.75,-0.5,-0.25,0,0.25,0.5,0.75,1) z<-

DeaR list, I'm trying to represent some information via 3D plots. My data and session info are at the end of this message. So far, I have tried scatterplot3d (scatterplot3d), persp3d (rgl), persp (graphics) and scatter3d (Rmcdr) but any of them gave me what I'd like to have as final result (please see [1] for a similar 3D plot changing PF by ypred, pdn by h4 and pup by h11). In general

Dear R-users, within the rgl-package, I would have a question about the usage of persp3d in combination of rgl.viewpoint. I am not able to figure out how to let a 3D plot rotating around likewise the example in ?rgl.viewpoint. It seems that when I use persp3d(...) I see something on my screen, which is different from what I get when it's rotating. Is there any different behavior between

Dear All, I have made a scatter plot and placed a plane within it using scatterplot3d. However, I have been asked for the data points to be a surface plot or have the plane more closely resemble the data rather than show trends. I have since tried to use the rgl package. Why doesn't this package use the window which already contains graphics? I have one axis with decreasing values and two

Unfortunately that's not really an R question. I recommend that you read up on the statistical methods underneath. One that I'd wholeheartedly recommend is Prof. Harrell's `Regression Modeling Strategies'. [BTW, there are now two implementations of gam() in R: one in `mgcv', which is fairly different from that in `gam'. I'm guessing you're referring to the one

I am new to R and what to find out which package would be best to create a surface plot, 2d or 3d if possible. I have a matrix (depth.dat) which has over 15k depth measurements from an ultrasonic corrosion mapping application. These depth measurements only have one axis (x) but I have used Octave and gnuplot providing decent results, but R seems to have a web interface with PERL which is what I

I have been making simple functions to display regressions in a new package called "rockchalk". For 3d illustrations, my functions use persp, and I've grown to like working with it. As an example of the kind of things I like to do, you might consult my lecture on multicollinearity, which is by far the most detailed illustration I've prepared.

Hello, say I have a 2D-matrix (indexed by x and y), which contains z values, which I want to plot over x-y. Either dotted, or if possible as a landscape. I tried around with persp and plot3d (from rgl) and persp3d (from rgl). I sometimes get something that looks good and a while later, when trying some new data I need to worry about that again. Is there something lika a convenience function

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:

Hello, I'm not getting a great looking 3d graph when plotting my z values: x <- seq(0.0, max(d1), max(d1)/20) y <- seq(0.0, max(d2), max(d2)/20) z <- matrix(NA, length(x), length(y)) persp3d(x, y, z, phi=30, theta=30, scale=TRUE,shade = 0.75, col=pal[col.ind], xlab=var.name[1], ylab=var.name[2], main="3d plot") Are there other options like persp3d where I
