...special connection parameters (from R) through the RODBC package or do I have to setup an intermediary XL table (pivottable linked to the OLAP cube) and then connect to the XL data source from R? I would appreciate any reference / pointer to OLAP/R configuration instructions. Thanks. Olivier Collignon

Hi, I would like to know if there is a way to change a vector of arbitrary size to make it fits the nearest upper size multiple of a power of 2. -- Cordialy ---------------------------------------- Emmanuel POIZOT Cnam/Intechmer Digue de Collignon 50110 Tourlaville T?l : (33)(0)2 33 88 73 42 Fax : (33)(0)2 33 88 73 39 -----------------------------------------

...(of events defined by their start and end times) that elapsed during time intervals. Any advice on how to improve this code. I searched the email archive and looked at the MASS book but did not find anything specific that relate to that. Not sure how t/sapply could be used here?

Dear community, I'm currently attempting to predict the occurence of an event (factor) having more than 2 levels with several continuous predictors. The model being ordinal, I was waiting the glm function to return several intercepts, which is not the case when looking to my results (I only have one intercept). I finally managed to perform an ordinal polytomous logisitc regression with the

Dear community, I am currently trying to fit an ordinal logistic regression model with the polr function. I often get the same error message : "attempt to find suitable starting values failed", for example with : require(MASS) data(iris) polr(Species~Sepal.Length+Sepal.Width+Petal.Length+Petal.Width,iris) (I know the response variable Species should be nominal but I do as levels

Dear community, I am currently attempting to perform a (L1) penalized ordinal logistic regression with proportional odds. For the moment I only found R packages allowing to perform forward or backward continuation ratio model with several penalizations. Does anyone have a clue of what R package I could use ? I am not even quite sure that penalized logistic regression with proportional odds has

Hello all, ever since whe upgraded to samba 2.0.2 we are getting the following error [1999/03/01 19:12:52, 0] lib/util_sock.c:write_data(407) write_data: write failure. Error = Broken pipe This error occurs on almost every write to the server... Sometimes this results in corrupt files. Is there a solution to this problem ?? Thanks, Marc
