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 =

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

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 <-

Hello users! I'm calculating a simple model using svm(...) from the e1071 package. So far so good, with a linear kernel I'm getting 5 SVs. When plotting the result I see very well separated data clouds, but the underlying color is constantly pink, so as far as I understand no class separation is shown... I would be happy if anyone could explain me this behaviour because I think I have a

Hi, I can't believe I am unable to do this. I just installed R (never used it before, but want to learn it). At present, though. all I want to do is export a data file (specifically "crabs" in the MASS library) to a text file for use in SPSS. It allows me to peek into the dataset, using the command head(crabs) but I can neither view the entire file nor can I seem to export it to a

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

Hallo, I have a question concerning SVM regression in R. I intend to use SVMs for feature selection (and knowledge discovery). For this purpose I will need to extract the weights that are associated with my features. I understand from a previous thread on SVM classification, that predictive models can be derived from SVs, coefficiants and rhos, but it is unclear for me how to transfer this

Dear R people, I am trying to plot the results from running svm in library(e1071). I use plot.svm. After searching through the help archives and FAQ, I still have several questions: 1. In default, crosses indicate support vectors. But why are there two colors of crosses? What do they represent? 2. I want to draw a white-gray colored plot and modify the different colored crosses or circles by

Dear all, I'm a trainee statistician in a company and we'd like to understand svm mechanism, at first with simple examples. I use e1071 package and I have several questions. I'm working with data extracted from cats data (from R). My dataset corresponds to a completely separable case with a binary response variable ( Sex with 2 levels: F and M), two explanatory variables (Bwt

Hi list, I have the problem, that a samba 2.2.8a server cannot validate the password with a samba 3.0 pdc for a client request. A samba 2.2.1 works fine. Let me explain the situation in more detail: samba 3.0 pdc machine a samba 2.2.8a server machine b (doesn't work) samba 2.2.1 server machine c (works) samba 2.2.8 client machine d Machine b and c should authenticate the passwords

Hi there, I have a problem I can not solve myself. I have samba 3.0.28 installed on a Ubuntu 8.0.4 server. Samba is a member of AD. Authentication is kerberos, user- / group ids are handled by nis (Windows 2008 SFU / NIS Server). My Samba config: [global] write list = admin,rado,@Administratoren deny hosts = 0.0.0.0/0.0.0.0 client schannel = No allow hosts = localhost,

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

Very few computer programs do that. You cannot `require' two digits by options(digits=2): ?options says digits: controls the number of digits to print when print- ing numeric values. It is a

Hello all, I'm running slackware linux 8.0 and tries to configure samba 2.2.8a as PDC. I succeded configuring network shares i.e. netlogon, profiles, etc. Everything is OK, but when i tries to make a domain logon using windows 98 apears an error "Wrong parameter".

Hi, We've had our business server functioning dandy for a long time, with SAMBA acting as a domain controller for our Windows XP pro clients. No issues. All was lovely. We're running Suse 9.3, Kernel 2.6.8-24.14-smp, Samba version Version 3.0.9-2.3. Now, it was time to upgrade hard drives in the RAID controller, to create a 200 gb container (rather than the 100 gb container we had). So,
