Hi All, I have data with 400 individuals and the following information Grade: pass or fail coded as 1 for pass and 0 for fail Sex: male or female ( coded as 1 for male and 2 for female ) Age Teaching.method : can be 1,2,3 I want to fit a logistic regression where the outcome if (1=pass or 0 for fail) and the rest of the variables are the regressors. My question is that I am not sure when to use ?factor? for a variable. In my example, Grade, sex, teaching method are categorial variables...

Dear R-users, Is there a function in R that classifies data in more than 2 groups using logistic regression/classification? I want to compare the c-indices of earlier research (lrm, binary response variables) with new c-indices obtained from 'multiple' (more response variables) logistic regression. Best regards, Stephanie Delalieux Department Biosystems M?-BIORES Group of Geomatics

Dear R-Users, given you have been teaching R to students (grad level, mainly social science background, no previous programming experience, 80% know SPSS), what are your experiences concerning the style of teaching? Do you prefer to stand in front of the class like in "normal" lectures and you show them slides? Or do you you ex...

Hi everyone I am teaching a lecture on hardware/software codesign which, though not a dedicated compiler course, covers quite a bit of compiler related contents (general introduction, intermediate code, code generation). I'm currently considering replacing and/or extending this compiler related lecture parts with an...

Hi R People: I'm teaching a statistical computing class using R starting next week (yay!) and I have an opinion type question, please. I'm old school and use "<-" in an assignment. However, I'm starting to see the "=" in the literature. Which should I use or does it matter, please? Than...

...ntrinsics so adding add and sub just follows that > precedent. If the decision is made to move masking to the core > operations, the new intrinsics would just move as well. How will existing passes be taught about the new intrinsics? For example, what would have to be done to instcombine to teach it about these intrinsics? Let's suppose every existing operation had an equivalent masked intrinsic. Would it be easier to teach all of the passes about them or would it be easier to teach the passes about a mask operand on the existing Instructions? Would it be easier to teach isel about a...

...u use it and thankx for the encouragement re my talk.... Please note that I do not claim to have ellicited a reply from all users of R, this is a quick survey not a census. I have tried to break the responces down to the following categories: Where: (hopefully my geography is not as bad as my teachers claimed??) When: Undergraduate level or post graduate level. I included all the posts that i recieved. Thank you. jeremy ----------------------- Where: Austria Vienna University of Technology, Department of Statistics Vienna University of Economics and Business Administration: Vienna Un...

Hi folks, I''m working with a local high school in the Portland, OR area on the subject of computer science curriculum. We are thinking of introducing a class in web development and I think Rails would be a perfect vehicle. I''ve done some searching on the web but haven''t found any suggestion of HS curriculum for Rails. Any pointers or suggestions? Thanks, ---

Dear R People: I will be teaching an undergraduate Design of Experiments class in the Spring Semester. It will be very much an applied course. My question, please: has anyone used R for a course like this, please? I've tried Rcmdr for a regression course and just plain command line for a time series course. Should I use...

Hi, Trying to setup a logistic regression model. (Something new to me. I usually use SVM.) The person explaining the concept explained to me that I can include a "group" variable so that the probabilities predicted by the model will be "per group" Does this make sense to anyone? If so, how would I implement this? Using the glm or lrm function? Thanks! -N

Hi all, I will be teaching a graduate-level course on R at CU Boulder next semester. I have a teaching idea that might also help improve the R wiki page... I wanted to know what you all thought of it and wanted to solicit some advice about doing it. During the latter part of the course, students will choose a topic of in...

Hi I am a programming pleb, however I would like to learn how to write my own functions and methods. Can anyone suggest a good place to start teaching myself, readings or other?

Hi all, We are preparing for a future batch, and we may be shorthanded for teaching. R is our programming language of choice. Data Science Retreat (DSR: http://datascienceretreat.com) sits at Microsoft Ventures offices in Berlin Mitte. We have chief-data-scientist mentors and a pretty exhaustive program on machine learning + data science. You can check it out here: http://datas...

Hello, I am looking for CRAN packages that don't teach bad habits. Can I have suggestions? I don't mean the recommended packages that come with R, I mean the contributed ones. I've been sampling a lot of examples and am surprised that many ignore seemingly agreed-upon principles of R coding. In r-devel, almost everyone seems to support the &...

I wonder if you can have more than one has_many :through association between 2 models. For example... I have a model Teacher and a model Class Now, 1 Teacher works in many Classes, right?. So I need a join model like class Work < ActiveRecord::Base belongs_to :teacher belongs_to :class end But I also would like to know if a teacher CAN teach a class before I assign him or her to one class....
