Dear users, I'm working on binary classification problem using Support Vector Machines (SVM). My objective is to train a series of SVM models on a grid of hyperparameters and then select those that maximize the AUC based on an independent validation sample. My attempted code is shown below. It runs well on "small" data sets but when I use it on a slightly larger sample (e.g., my

...think that if the files are tiny, there's no problem to use this solution over wan.. ? But okay, if file are large.. (don't know .. 100MB - 200MB and more.) i understand that it depend of the internet connection and that's the replication can be so soo soo slow.. Please, give me some renseignments about this solution over wan Shayn

Is there an easy way to compile a packages's fortran so that it has the information for ddd or gdb to follow the lines of the code? I seem to remember seeing something about this, but I cannot find it in Writing R Extensions. (I see about Valgrind, debugging a segfault, and some other tricks, but what I really want is to follow the fortran logic.) Thanks for any pointers, Paul

Hi, All Forgive me if this is a stupid newbie question. I'm having no luck googling an answer to this, probably because I don't know the right R terminology to frame my question. I want to know how to run an R function on each combination of the values of 2 or more variables. In SAS-speak this is multiple "BY variables" or "CLASS variables". In R I've figured

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,

I'm trying to narrow down the source of a bug where a docker container sshd closes the connection after a successful authentication (https://bugzilla.redhat.com/show_bug.cgi?id=1085081) - filed with libvirt as there's no docker-io component for RHEL 6.5 in bugzilla. One of the steps I'm taking is to reproduce a similar setup using LXC but while it seemed to have worked I'm not

I'm using R 2.11.1 on Win XP (32-bit) with 3 GB of RAM. My data has (only) 16.0 MB. I want to create a VCorpus object using the Corpus function in the tm package but I'm running into Memory allocation issues: "Error: cannot allocate vector of size 372 Kb". My data is stored in a csv file which I've imported with "read.csv" and then used the following to create

Is CRAN having trouble or is it just me? (The web interface is very slow and install.packages() is timing out and giving me "service not available").

I am trying to extend an S3 method to work with an S4 object as well as the S3 objects it works with, but UseMethod does not seem to recognize the S4 class and dispatches to the default method. Is this to be expected or should I be looking for an error in my code? If it is not an error in my code, is there an easy way to do this, or do I have to convert the generic to S4 and then make those

I am trying to check my packages with R-rc and latex is failing to find utf8.def. I presume my latex installation is defective or too old, or is this file distributed with R and I just don't have a path set correctly? Paul ______________ * checking PDF version of manual ...

I was trying to subscribe to an RSS feed from <http://developer.r-project.org/RSSfeeds.html> but IE chokes on DTDs and Firefox also has trouble with this feed. (I'm not sure if it has trouble with DTDs in general.) I went to one of our web developers to see what I should use to read the feed, and he pointed out that the mix of RSS 2.00 and rss-0.91 looks like a mistake: <!--

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, All I have a data frame like this. > names(x) [1] "month" "alloc_gb" One of the columns contains the dates I want to use: > data.class(x$month) [1] "yearmon" I would like to make a time series object out of this. However the ts function seems to require me to spell out the starting date. Is there a way to tell ts to use the date column I already

I have recently upgraded samba to 3.6.23-9.el5_11 and have noticed all new users created can not be seen with using the samba config tool within CentOS or within the samba webmin module. I can manually log in and look the account information within the smbpasswd file and can query it using pdbedit. I need to be able to edit this information from within the webmin module as there are a number

Is it possible in R to call a fortran routine that sets variables in a common block and expect the values to persist when a call is made from R to a second routine that uses the common block? If not (as I suspect), is it possible to use a common block in a group of routines that are used together, for as long the routines do not return to R? Paul

Hello list, I want to authenticate (only authenticate) through active directory with PAM. I googled around and everything I found, wheter it is forum posts or howtos, it always talks about winbind and joining the linux machine to the windows domain. I do not which to do this, I only want to get PAM to authenticate with the AD and then everything else is local. Should I use pam_winbind ?
