Hi, I am new to R and here is what I am doing in it now. I am using machine learning technique (svm) to do predictive modeling. The data that I am using is one that is bound to grow perpetually. what I want to know is, say, I fed in a data set with 5000 data points to svm initially. The algorithm derives a certain intelligence (i.e.,output) based on these 5000 data points. I have an additional

Hi users! I am fitting a model with several factor variables as independents using svm. since there are lots of categorical variables,the training and test data sets have been created using dummy.data.frame option from dummies package. I have a factor A in the training data set with 2 levels (0,1).In the test set, this factor A has only 1 level (1) and hence when applying dummy.data.frame, the

Hello, It would be a good idea to update the Documentation about CIFS: http://gluster.com/community/documentation/index.php/Gluster_3.2:_Exporting_Gluster_Volumes_Through_Samba When the simple truth is, that there is no CIFS Support in gluster itself - it should not be in the docs. As I found out, this was also suggested earlier: http://www.mail-archive.com/gluster-users at

Hi Abbas, Before I try to give you answers, I just want to mention that you should send R related reqests to the R-help list, and not me personally because (i) there's a greater likelihood that it will get answered in a timely manner, and (ii) people who might have a similar problem down the road might benefit from any answer via searching the list archives ... anyway: On Sep 5, 2009, at

I have compiled and linked a 64 bit version of R (R 2.9.2) and the corresponding unix ODBC 64 bit package The red highlighted text below is the error I'm getting trying to when invoking a sqlQuery > library(RODBC) > channel <- odbcConnect("OraLSH", <user>, <password>) > sqlQuery(channel,"select sysdate from dual") Error in .Call(C_RODBCFetchRows,

I hope someone can point out my stupid error, because I'm baffled. I am calculating a bunch of variable values and then placing them in a document using odfWeave tags. This is working very nicely for every spot except one. One of the values I calculate is traindev: traindev <- if (trainlength>0) round(sd(trainscores, na.rm=T),1) else "" when I try to insert this traindev

I'm unable to open an SPSS file over my network. If I copy it to my local C:/ drive I can read it. I saved the command (in a "crib sheet" text file) in order to avoid all the typing, so I'm pretty sure I've done it before. I verified that the file I'm trying to read is OK. This is what happens: > SurveyData <-

Yes, I am a newbie at R, but it is not the complex commands in R that have me baffled, but simple data commands. For example, why does something like: > plot(Girth ~ Height) *not* work after a command that allegedly loads the data: > data(trees) with the error message: Error in eval(expr, envir, enclos) : Object "Girth" not found but does work after the command: >

Hello All, I've created a function as follows so as to use it in a loop. freq<-function(i) { library(RODBC) paste(i,"<-sqlQuery(conn,","'","select click_flg, open_flg,", i ," from modeling_5')",sep="") } freq(i="AQI") [1] "AQI<-sqlQuery(conn,'select click_flg, open_flg,AQI from modeling_5')"

On *certain* fields in my rails forms the backgrounds are yellow. If I check the page source there is no clue as to why. However, if I *save* the page to disk and then open it in a text editor I can see that the affected fields are like: <input style="background-color: rgb(255, 255, 160);" id="contact_first_name" name="contact[first_name]"
