Hi, I'am using the sentient analysis available in "R2.15". Now the challenge that I'am facing is that the Naïve Baye's has an inbuilt list of 6500 words in which it has been trained. So my question that can I increase the number of words on which this algorithm is trained? In case i can increase the list can someone tell me the procedure? Regards Nalin American Express

Hi, I have a logit model built in R which I am trying to validate . Could you please help me with creating lift charts and area under ROC for the same. I am trying to use package ROCR The indicative code for this is : newlogit3<- glm(Attrition_ind ~ Time.in.AXP+ Age +as.factor(Increase.in.Rating.in.Current.year) +as.factor(Below.Market.Merit.Budget)+as.factor(Drop.in.AIA)

Hi, I am stuck with creating a conditional categorical variable in R If my dataframe data_2 has 3 variables A,B,C I want to create variable D which would be something like : data_2$D <- ifelse(data_2$A < data_2$B & promotion_ind =="N",1,0), this throws up an error "In Ops.factor(data_2$A,data_2$B) : < not meaningful for factors I have tried converting the

Hi everyone, I am trying to validate a logistic model built in R. Not my version of R is 2.12 and I cannot install ROCR. I have gone to a point where I have the predicted values using the code: pred1 = predict(trainlogit1,testdata_1, type = "response") How do I proceed from here? Is there another way in which I can plot lift charts? My model output is: Call: glm(formula =

Hi, I am trying to do some predictive modeling around attrition and want to split the dataset into test and train (80:20) and keep the ratio of attritees:non attrites same. In my dataset the attrition indicator is coded as 0(for non-attritees) and 1 (for attritees) and I want to keep the ratio of 0's to 1 similar. I apologize for this trivial question but this is my second week with R.

Hello everybody, I met a problem when I configure the samba for our company. The case is, 1. We have to use Windows Domain to authenticate the user. 2. Only a few domain users can access the samba server. 2. We wanna all the allowed domain users are mapped to 1 unix userid: checkpoint. The Window Domain auth is working perfect. And if we created the unix id same as the domain users,

Could someone please elaborate on the technical differences and practical impact of whether choosing memory-based tables in MySQL or using memcached. I got this far on my own: It seems that MySQL uses the NDB engine for transaction-safe memory access in a cluster. the memory storage engine seems to be faster but not synchronizable by any means in a cluster. memcached seems to be ultimately fast

Hi - this is my first day with Ruby on Rails. I''m starting out by working through the Helloworld (Hello Ruby) example program printed up in "Agile Web Development with Rails." My steps are as in the text: 1. ruby script/generate controller Say 2. edit the proper file and add the hello method 3. fire up the browser using address http://localhost:3000 4. fire up the

Here''s a gedanken experiment for those w/ far more knowledge than I about ActiveRecord, etc.: Let''s say my database is very remote and on a very slow machine. Let''s further say that my app has an action that leads to a very simple insert into the "impressions" table of the db, a la "INSERT INTO impressions(docid) VALUES($docid);" - and

Dear R-list, I wish a very happy new year and send you a little question: I have different variables which names are m1, m2, m4, .., m10, ... and want to obtain for example mean of each of them without typing each mean(m1), mean(m2), .... What is the solution for decomposing names in mXX? With my best regards, EA. ============================================ Erik-André SAULEAU SEAIM Hôpital du

Dear R-list, I try to adjust GLMM on incidence cancer data. Without random effect, in GLM the command is, for example with sex effect, glm(Observed~sex+offset(log(Expected)),family=poisson) because the observed are Poisson distribued with parameter Expected*incidence rate. But know I want to introduce random effect (for example spatial effect) and it seems to me that the "offset" does

Server - HPUX 11.31 Clients - WIN7 WIN10 After upgrading my versions to 4.9.0.0 I've noticed that we're unable to connect to our AD joined SMB HP-UX Server any longer. Could someone tell me where to begin digging in release notes between 3.6.6-4.9.0.0 to find out what changed in the smb.conf file that would be causing our problems? Here's a somewhat similar .conf output global]

Hello R-List I use DClusters package (I work in a cancer regestry). I have 2 questions about it: 1-how is it possible to get back the bootstrap pValue? I mean the pValue of the calculated statistic with respect of the distribution of this statistic under the null hypothesis. 2-how is it possible to test an overdispersion in the poisson model? for choosing a best model I need this mesure of

Hi, See below I reply your message for <https://stat.ethz.ch/pipermail/r-help/2008-April/160966.html>[R] predict.glm & newdata posted on Fri Apr 4 21:02:24 CEST 2008 You say it ##works fine but it does not: if you look at the length of yhat2, you will find 100 and not 200 as expected. In fact predict(reg1, data=x2) gives the same results as predict(reg1). So I am still looking for
