similar to: R-beta: Where to begin with R?

I see that feature freeze for a better than ever R has been announced. May I ask if there will be or could be "merge" function for data frames? I believe it would be very nice if this were "centrally" implemented (with regard to my humble steps to writing such a function and the related error and other precautions). I know from VR2R.pdf (courtesy Profs. Venables and Ripley)

Good day Sir/Ma'am! This is Alyssa Fatmah S. Mastura taking up Master of Science in Statistics at Mindanao State University-Iligan Institute Technology (MSU-IIT), Philippines. I am currently working on my master's thesis titled "Comparing the Three Estimation Methods for the Four Parametric Logistic (4PL) Item Response Model". While I am looking for a package about Markov chain

I am trying to run, in R -Windows95, the example in MASS2, section 17.2. When I run predplot() on cush.lda I get > predplot(cush.lda, "LDA") Error: couldn't find function "max.col" I get the plot OK, but within predict(), it balks on max.col A more general question about using VR. Is there an easy way to use library on VR in general or do I have to move each into

I'm trying to do a sort of home-brew item-characteristic-curve. This is a plot of the probability of getting a test item correct, as a function of the mean score on the test. (The last part is the home brew part.) Logistic regression with glm would work nicely, EXCEPT for the fact that the curve requires a guessing parameter. So the asymptote on the left is not 0 but rather something like

I know of no existing functions for estimating the parameters of this model using MCMC or MML. Many years ago, I wrote code to estimate this model using marginal maximum likelihood. I wrote this based on the using nlminb and gauss-hermite quadrature points from statmod. I could not find that code to share with you, but I do have code for estimating the 3PL in this way and you could modify the

This was ``accidentally'' only sent to me.

Dear friends. This is again a very simple question, and I hope you will accept it. I have a dataset with variables in columns all with their names. Now I want to add a column indicating simply identity of patients, numbered according to row. There are 34 rows. So I did: >ID <- c(1:34) but was not allowed to >Ptt <- cbind(patients,ID) and was informed that >Error: names attribute

Versions of the V&R libraries, VR_5.3pl025-1.tar.gz, and of tree_0.2-2.tar.gz (giving most of the functionality of S's tree system including all that I have ever used) are now available on CRAN's Vienna node, and will propagate. There is an early draft of an R user's complements on Venables & Ripley available from http://www.stats.ox.ac.uk/pub/MASS2/Compl.shtml This is

My sincerest apologies, as this is a very elementary problem, but I have searched through archives and FAQs and on the web, and I am at the end of my own resources. I need to do analysis of a spatial point process occuring with four counties, using spatstat. I've had no trouble importing the shapefiles, but I can't seem to figure out what I need to do in order to use the boundary as an

Hi, I am very new in this list.. I want each of my internet users to be limited in his/her usage of bandwidth. The limitation will be done in my squid (linux) box, as they all have to be authenticated by squid before going to the internet jungle.. Then anybody here could tell me where to begin to do such thing ? Any idea/solution would be very appreciated TIA regards, aqil

Hi, here's a short summary of all the mails I got concerning the R help system during the last days ... I really want to have all open questions in this list, so if I forgot your most important topic please forgive (and remind me again) ... it's probably only because of lack of time such that I had to compile the list in a hurry ... Ok, here we go: 1) It would be useful to have a button

I have some Bernoulli data something like this: x<-sort(runif(100,1,20)) p<-pnorm(x,10,3) y<-as.numeric(runif(x)<p) plot(x,y) lines(x,p) This plot is not very satisfactory because the ogive does not visually fit the (0,1) points very well, and also because the points tend to fall on top of one another. The second problem can be eliminated by adding vertical jitter. However I was

Hi- I''m working in the IT department of a small liberal arts university-- we''re getting *massacred* by P2P traffic. Informal testing/probing indicates that about 60% of our traffic from the dorms was P2P-- we''ve taken the initial step of hardlimiting the dorms to no more than 40% of outgoing university bandwidth. Also, we''ve blocked the
