similar to: invalid variable type in model.frame within a function

Dear Ben, Perhaps I'm missing the point, but contrasts.arg is documented to be a list. From ?model.matrix: "contrasts.arg: A list, whose entries are values (numeric matrices or character strings naming functions) to be used as replacement values for the contrasts replacement function and whose names are the names of columns of data containing factors." This isn't entirely

I apologize for posting on this question again, but unfortunately, I don't have and can't get access to MASS for at least three weeks. I have found some code on the web however which implements the prediction error algorithm in cv.glm. http://www.bioconductor.org/workshops/NGFN03/modelsel-exercise.pdf Now I've tried to adapt it to my purposes, but since I'm not deeply familiar

Here is a proposal for improving DbgValueHistoryCalculator and the overall quality of debug locations. Focus: This is about lowering the DBG_VALUE machine instructions to DWARF location lists. Non-focus: This is not about (typical -O0) variables that permanently reside at a frame index and are described with dbg.declare intrinsics in the IR. These variables are stored in the MMI side-table and

Hello, Is is possible to do "shorewall reject 1.1.1.1 tcp 25" ? So I can dynamically blacklist offensive smtp senders, but only have shorewall reject certain types (smtp) traffic from them? Thanks, Alex Martin http://www.rettc.com

Hi List, While (bluntly) testing the prerelease version of dovecot on our mailfarm (just for the webmail imap) we noticed some small problems: - While our OLD dovecot/imap drove the load to a maximum of 1 over a day after running, the new dovecot/imap pushes it easily to 20. This is mainly due to a LOT more disk activity. This is probably caused by the fact we a) use indexes on disk and

An lme4 user pointed out <https://github.com/lme4/lme4/issues/491> that passing contrasts as a string or symbol to [g]lmer (which would work if we were using `contrasts<-` to set contrasts on a factor variable) is *silently ignored*. This goes back to model.matrix(), and seems bad (this is a very easy mistake to make, because of the multitude of ways to specify contrasts for factors in R

Dear Martin and Ben, I agree that a warning is a good idea (and perhaps that wasn't clear in my response to Ben's post). Also, it would be nice to correct the omission in the help file, which as far as I could see doesn't mention that a contrast-generating function (as opposed to its quoted name) can be an element of the contrasts.arg list. Best, John > -----Original

I am getting some unexplained changes in the latest version of survival, and finally traced it down to this: model.response acts differently for Surv objects. Here is a closed form example using a made up class Durv = diagnose survival.?? I tracked it down by removing methods one by one from Surv; I had just added some new ones so they were my suspects. test <- data.frame(time=1:8,

This post is NOT a question, but an answer. For readers please disregard all earlier posts by myself about this question. I'm posting for two reasons. First to say thanks, especially to Dimitris, for suggesting the use of errorest in the ipred library. Second, so that the solution to this problem is in the archives in case it gets asked again. If one wants to run a k-fold cross-validation

Hi List, While testing with dovecot-1.0-test8 on our platform, I get al lot of these: May 11 11:42:50 mf1 dovecot: imap(user at domain.tld): Our dotlock file /var/mail/mounted/d/do/domain.tld/user/Maildir/.INBOX/ dovecot.index.log.lock was modified (1084268570 vs 1084268875), assuming it wasn't overridden This is probably due to some time-issues on our platform, and the load the

Percentage tables are useful in educational contexts, whereas
