Hi, Suppose I have the following data frame. __BEGIN__ > library(MASS) > data(crabs) > crab.pca <- prcomp(crabs[,4:8],retx=TRUE) > crab.pca$rotation PC1 PC2 PC3 PC4 PC5 FL 0.2889810 0.3232500 -0.5071698 0.7342907 0.1248816 RW 0.1972824 0.8647159 0.4141356 -0.1483092 -0.1408623 CL 0.5993986 -0.1982263 -0.1753299 -0.1435941 -0.7416656 CW

I've been experimenting with the lattice graphics in chapter 3 of MASS. The code to produce figure 3.14 is: data(crabs) library(mva) lcrabs.pc <- predict(princomp(log(crabs[,4:8]))) crabs.grp <- c("B", "b", "O", "o")[rep(1:4, rep(50,4))] splom( ~lcrabs.pc[, 1:3], groups = crabs.grp, panel = panel.superpose, key = list(text =

Can anyone explain the root of my problem? When I type the following code into R, I receive 42 support vectors insted of the 21 stated in the book 'Modern Applied Statistics with S': library(MASS); library(e1071); library(class); lcrabs <- log(crabs[,4:8]); (svm(crabs$sp ~ ., data = lcrabs, cost = 100, gamma = 1)); By changing the value of gamma I can obtain only 21 support vectors,

Hi, When I tried an example of the xgobi function, I got the following error. Could someone explain to me what is wrong ? Thanks a lot. xgobi(crabs,colors=c("SkyBlue","SlateBlue","Orange","Red")[rep(1:4,each=50)]) c:/PROGRA~1/R/R-23~1.1/library/xgobi/scripts/xgobi.bat -vtitle 'crabs' -std mmx

I have created an xyplot of a time series with the following code... win.graph(width = 10, height = 7) panel1 = function(x, y) { panel.loess(x, y, lwd=2.5, span=0.5, col="gray") panel.xyplot(x, y, pch=19, col="blue", cex=1.25) } xyplot(oneplusdensity ~ year, data=figdata, aspect="fill", cex=1.5, xlab=NULL, ylab=expression("Crabs per

Hi, I’d just like to interject to say that building within Visual Studio isn’t really that bad. Running the lit tests is a bit painful because the LLVM build tools that are integrated with the build system don’t play nice with msbuild. Particularly, I’ve never been able to actually cancel an invocation of lit or tablegen via visual studio. That said, there is a huge upside to building with

Hi Team, I have checked out the clang and llvm source code and built the executables using the visual studio 2015 community edition. I am using Windows as my platform. However I see that there are some test cases under the clang test folder in the LLVM.sln. Eg AstMatcherTest,ASTTests etc. I see that these tests make use of the Google test framework. In my visual studio I have

I'm trying to get the coefficient of partial determination for each of three independent variables. I've tried mvr in package pls.pcr. I'm a little confused by the output. I'm curious how I can order the LV's according to their names rather than their relative contribution to the regression. For instance, using the crabs data from MASS I made a regression of FL~RW+noise

I'm trying to learn how to create Trellis multi-panel plots, but I'm having some trouble reproducing the graphs shown in Venables & Ripley (2002) (e.g., Figs 4.14 & 4.15). Actually, everything looks fine except for the fact that I can't see any text above the individual panels. I'm using R 1.9.0 for OS-X running on Mac OSX 10.3.3, and I'm drawing the graphs into

Hi all, I have a question about the SOM routine. You can either supply the initial representatives for the lattice yourself or else they are chosen randomly from the dataset. Is it possible to pass the random-seed as an argument somehow, when choosing the random initialisation of the lattice? As it is now, each time I run a SOM on a dataset with the same settings the resulting SOM will still

Hello, dear R users. What is the easiest and the most visualli understandable way to analize dependency of numerical variable on two factors? Is the boxplot(y~f1+f2) the good way? It seems that this formula does not work. -- Evgeniy

I am using lattice to make figures as pdfs: trellis.device(device = "pdf",file = "Figure6.pdf",color = FALSE) I need to specify some blank space on the left-hand margins (the pages will be bound so we need about 0.5 inch)). I have tried a number of solutions but none seems to work (e.g. par.set). Can this be done when initiating the plotting device? Or is the some other way

Hello could you please tell me what is the function to get the absolute value of the real or complex number. most of other languages it is abs(x) , what is it in r? I did few searhces in the help docs for no avail. thanks F.J

Hi, I have a rails app which currently does the following "After the launch of the page, there is a button click which starts another ruby script on server using system(ruby <file-name>)" This execution may take a while around 5-10 mins. I have following questions 1. While the script is being executed are other connection requests to server waiting or are there services? 2. Is

Hi All, I was wondering if SAMBA server can be used to export CFS (Cluster File System) mounted partitions. That is, can you view a CFS directory present on a UNIX machine, from a Windows machine, with the SAMBA server running on the UNIX machine without any hitch. If so is there any issue related to performance or something? Could you please clarify this for me? Also can multiple SAMBA servers

Dear R users, I want to do discriminant analysis on my data. I have successfully followed the discriminant analysis in V & R on the iris data: > ir <- rbind (iris3[,,1],iris3[,,2],iris3[,,3]) > ir.species <- c(rep("s",50),rep("c",50),rep("v",50)) > a <- lda(log(ir),ir.species) > a$svd^2/sum(a$svd^2) [1] 0.996498601 0.003501399 > a.x <-

Hi folks, We would like to add SeaHorn <http://seahorn.github.io/> and Crab-llvm <https://github.com/seahorn/crab-llvm> to the list of LLVM's users on http://llvm.org/Users.html under Open Source Projects. The descriptions would be: 1. SeaHorn | An Algorithmic Logic-Based Reasoning Framework. 2. Crab-llvm | A static analyzer based on abstract interpretation for LLVM. I attach a

Ben Bolstad experienced something odd while running R CMD check over a package of ours using r-devel (yesterday's fresh). He tracked down the problem to a vignette calling 'library(MASS)'.
