Hi, all. I didn't find something similar to this problem in past list. I have a data frame (named restr) where some columns are factors, like you can see: > table(restr[,"p1"]) 0 1 2 3 4 5 0 26 1 0 1 0 > table(restr[,"p2"]) 0 1 2 3 4 5 6 0 13 11 1 2 1 0 When I use apply, the factor structure is missed: >

Hello. I am still a newbie in R. Excuse me if I am asking something obvious. My efforts to get an answer through browsing the mailing archives failed. I want to perform an augmented Dickey-Fuller test and to obtain AIC and BIC and to be able to impose some linear restrictions on the ADF regression so as to decide the correct order of autoregression. However I could find no obvious way to impose

Dear list, In my previous email, the model I'd like to estimate is rea=a*st+b*mod+error, where a+b=1 and a,b>0. My apologies for the misunderstanding.

Hello! I'm afraid that I don't understand redhat's bugzilla -- there's an approx 10-character wide box for reporting the bug and it always claims that that's not a bug. I'm sure I'm missing something. Anyway, here's the problems: Using Centos 5.2 and the "Software Updater/Package Updater/pup", I winnowed the problem updates down to six packages:

Dear R-users, I would like to know if there is any way to minimize || y - Xb||^2 under the constraint b'b=1. Thank you Giancarlo

While lm() is a linear modeling, the constraints make it easier to solve with a nonlinear tool. Both my packages Rvmmin and Rcgmin (I recommend the R-forge versions as more up-to-date) have bounds constraints and "masks" i.e., fixed parameters. I am actually looking for example problems of this type that are more recent than the ones that got me into this 30 years ago. Do contact me

Dear R users, I?m a beginner user of R and I?ve a problem with permutations that I don?t know how to solve. I?ve 12 elements in blocks of 3 elements and I want only to make permutations inter-blocks (no intra-blocks) (sorry if the terminology is not accurate), something similar to: 1 2 3 | 4 5 6 | 7 8 9 | 10 11 12 ----------1st permutation 1 3 2 | 4 5 6 | 7 8 9 | 10 11 12 NO - - 3 2 1

Just FYI. This machine has been offline and not updated for several months. I booted it and ran yum update. It generated an error. I googled the error, no hits. I did "yum clean all". Tried yum update again, it finished dependency resolution and reported some missing dependencies. I can deal with that. love and kisses, Dave Here is the tail end of the error output: ---> Package

I had updated by yum,however alway received the same result.

Dear all, I would like to aggregate a data frame (consisting of 2 columns - one for the bins, say factors, and one for the values) along bins and quantiles within the bins. I have tried aggregate(data.frame$values, list(bin = data.frame $bin,Quantile=cut2(data.frame$bin,g=10)),sum) but then the quantiles apply to the population as a whole and not the individual bins. Upon this

Hello, I have data for contour plot which is given in polar coordinates. Is there a straightforward way to plot in polar coordinates in R, or do i need to fiddle with transformations and then to sort the x and y vectors to be in ascending order as required by contour function and relatives? Cheers, Todor

Greetings. I'm running some models under R using glmmPQL from MASS. These are three-level models (two grouped levels and the individual level) with dichotomous outcomes. There are several statistics of interest; for the moment, I have two specific questions: 1.) This question refers to the following model (I present first the call, then the output of summary():

Dear R-users, I want to know if there is a package that allows to define different experimental designs (factorial, orthogonal, taguchi) and to compare them. I don't found one in the R-web site, but it is possible I missed it! Thank you in advance Sincerely, Marc

Hi- General question: I have written a function that performs a permutation test. I use the function "sample" to randomize my data, then I call on another function I wrote to analyze the randomized data. This process repeats "n" times-- 10, 100 or whatever. The function applied to the randomized data creates a matrix and sometimes the matrix contains NaN's. I would

I had some problems with apache, and there were so many, (caused by removing ispconfig) I decided to just remove and re-install. This is what happened when I tried to do so, both from remote and via console. I tried the DVD as well as yum, and got essentially the same thing. My webserver is down, and I'd sure like to get this fixed if anyone can help out. Begin errors: Component:
