similar to: subscripting a terms object

I posted this one as an R bug (https://bugs.r-project.org/bugzilla3/show_bug.cgi?id=14767), but Prof. Ripley says I'm premature, and I should raise the question here. Here's the behavior I assert is a bug: The output from delete.response on a terms object alters the formula by removing the dependent variable. It removes the response from the "variables" attribute and it changes

Martin, ? There are a couple of issues with [.terms that have bitten my survival code.? At the useR conference I promised you a detailed (readable) explanation, and have been lax in getting it to you. The error was first pointed out in a bugzilla note from 2016, by the way.? The current survival code works around these. Consider the following formula: <<testform>>=

Below is a SIMEX object that was generated with the "simex" function from the "simex" package applied to a logistic regression fit. From this mountain of information I would like to extract all of the values summarized in this line: .. ..$ variance.jackknife: num [1:5, 1:4] 1.684 1.144 0.85 0.624 0.519 ... Can someone suggest how to go about doing this? I can extract the

Hi R-help I have some question. First I have data in Excle ,then I would like to fit distribution from this data, how to import this data from excle? What's command? Thaks for first answer Second I learn R program from The Basics of S and S-plus book because it's basic, and then when I use command is attact(geyser) [follow from book] but I can't . Because it's command only S

Hi, I've performed an lda and obtained a classification table for some of my data: > efa.dfa<-lda(groups~.,efa.scores.8,CV=T) > str(efa.dfa) List of 5 $ class : Factor w/ 2 levels "1","2": 1 2 1 2 1 1 2 2 1 2 ... $ posterior: num [1:160, 1:2] 0.99083 0.00852 0.93983 0.23186 0.85931 ... ..- attr(*, "dimnames")=List of 2 .. ..$ : chr [1:160]

Hi, I'm running into an error message for the "anova"-function I never got before with the Design (Version 2.2-0) package.

Hi! The kernlab function kpca() mentions that new observations can be transformed by using predict. Theres also an example in the documentation, but as you can see i am getting an error there (As i do with my own data). I'm not sure whats wrong at the moment. I haven't any predict functions written by myself in the workspace either. I've tested it with using the matrix version and the

I would like to extract the names, modes [numeric/factor] and levels of variables needed in a data frame supplied as newdata= argument to predict.glm() Here is a small example illustrating my troubles; what I want from (both of) the glm objects is the vector c("x","f","Y") and an indication that f is a factor: library( splines ) dd <- data.frame( D =

Greetings R experts, I'm having some difficulty recovering lda objects that I've saved within sublists using the save.image() function. I am running a script that exports a variety of different information as a list, included within that list is an lda object. I then take that list and create a list of that with all the different replications I've run. Unfortunately I've been

This arose in testing [.terms and has me confused. data(esoph)?? # use a standard data set t0x <- terms(model.frame( ~ tobgp, data=esoph)) t1 <-? terms(model.frame(ncases ~ agegp + tobgp, data=esoph)) t1x <- (delete.response(t1))[-1] > all.equal(t0x, t1x) [1] TRUE # the above is wrong, because they actually are not the same > all.equal(attr(t0x, 'dataClasses'),

I have recently installed new untangle firewalls ( untangle.com) in Bridge mode at two office locations. Both offices collect mail from a Fedora 9, postfix,dovecot server at location #1. Since the install of the untangles i have been plagued by Thunderbird Errors while trying to POP email. The error says "RETR" command failed. If the user logs into the webmail (Squirrelmail) on the

This problem is likely to be specific to Windows, and particularly Win7. After a successful build of a package (R CMD build addendum), I immediately run an R CMD check for the same package. Not always, but _very_ often, I get the following error: C:\Users\nisabbe\Documents\@Doctoraat\R>R CMD check addendum Loading required package: tcltk Loading Tcl/Tk interface ... done Loading

Colleagues I am executing a length script in R (20K lines).

On January 5, I posted here concerning this issue (https://bugs.r-project.org/bugzilla3/show_bug.cgi?id=14767), and I have not heard any answers from people who think this is not a bug, or a simple accident in the delete.response function. The output from delete.response on a terms object alters the formula by removing the dependent variable. It removes the response from the "variables"

all.vars works fine, EXCEPT, it give a bit too much. I only want the regression variables, but in the following example I also get "k" the variable holding the chosen knots. Any machinery to find only "real" regression variables? cheers, Bendix library( splines ) y <- rnorm(100) x <- rnorm(100) k <- -1:1 ml <- lm( y ~ bs(x,knots=k) ) mg <- glm( y ~
