...ing Area Under Curve (AUC). I know ROCR package can do this job but I found all example in ROCR package have include prediction, for example, ROCR.hiv {ROCR}. My problem is how to produce prediction in SVM and to find AUC. Here is a simple example: library(MASS) library(kernlab) library(ROCR) pimamodel <- ksvm(type ~ .,data=Pima.tr,type="C-svc",C=10,prob.model=TRUE) pimamodel fitted(pimamodel) pima.pred <- predict(pimamodel, Pima.te[,-8], type="probabilities") pima.pred # try to find AUC #predid.no <- prediction(pima.pred[,1], Pima.te[,8]) #predid.yes <- pr...

Dear all For my research, I am learning classification now. I was trying some example about classification tree pakages, such as tree and rpart, for instance, in Pima.te dataset have 8 variables (include class=type): library(rpart) library(datasets) pima.rpart <- rpart(type ~ npreg+glu+bp+skin+bmi+ped+age,data=Pima.te, method='class') plot(pima.rpart, uniform=TRUE) text(pima.rpart) summary(pima.rpart) In the result I found only 5 variables: npreg,...

Dear R-helpers, First I apologize if my question is quite simple I have a large datasets which more 100 variables. For a research I need to change all name of variables with add one or more letters on each variables. For example, > data(Pima.tr) > Pima.tr[1:5,] npreg glu bp skin bmi ped age type 1 5 86 68 28 30.2 0.364 24 No 2 7 195 70 33 25.1 0.163 55 Yes 3 5 77 82 41 35.8 0.156 35 No 4 0 165 76 43 47.9 0.259 26 No 5 0 107 60 25 26.4 0.133 23 No > > dimnames(Pima.tr)[[2]]...

How do I install any version of samba onto a Windows 2000 server? Larry

Dear R users I have a very basic question. I tried but could not find the required result. using dat <- pima f <- table(dat[,9]) > f 0 1 500 268 i want to find that class say "0" having maximum frequency i.e 500. I used >which.max(f) which provide 0 1 How can i get only the "0". Thanks and best regards Muhammad Azam Ph.D. Student Department of Medical Statist...

Hi ,all : I am a newbie to here and I also install the 389 ds in our company for managering all users account and passwd .

If it could , then we were happy that can solve the user's vnc problem . Then , I

Hello, I plotted a nice tree with "ctree" . It shows 3 nodes with the prediction of my 2 groups. (see picture) Unfortunately I need a larger scale to read the exact prediction of my groups to get the specificity and sensitivity. I tried to change the scale with "axis" but it didn't work, my guess because it's not a normal graph with x and y axis. Has someone an idea

Hello to everybody here, We have a strange problem with ext3. df reports 28 of 30 GB to be used (rest may be slack) which it calls 100% used. But with du we can only find 13 GB, most of it actually in pretty large files (archives). Where are the other 17 GB gone?

I want to take the first row of each unique ID value from a data frame. For instance > ddTable <- data.frame(Id=c(1,1,2,2),name=c("Paul","Joe","Bob","Larry")) I want a dataset that is Id Name 1 Paul 2 Bob > unique(ddTable) Will give me all 4 rows, and > unique(ddTable$Id) Will give me c(1,2), but not accompanied by the name column.

We have samba 2.2.12 running on Solaris 9. Our PDC and BDC are windows 2000 servers running AD. Our windows admin is ready to promote a new windows 2003 R2 server to a DC. When she started DCPromo she received a warning message about older versions of windows and non-windows systems including SAMBA might not be able to communicate. Our configuration with SAMBA is not restrictive. Below is a

I have a Sun Clutster running on two Sun Fire 4800s, OS is Solaris 9. The environment was set up with PC Netlink prior to my arrival. On Nov 24 after work I shutdown PC Netlink on both systems and started Samba. However from the windows side we can only see one Sun box and the one sun development box that I tested on prior to this weekend. The other production system can't be seen from
