I am a statistician and I come up to an interesting problem in cryptography. I would like to use R since there are some statistical procedures that I need to use. However, I run into a problem when using the modulus operator %%. I am using R 2.2.1 and when I calculate modulus for large numbers (that I need with my problem) R gives me warnings. For instance if one does: a=1:40; 8^a %% 41 one

Hi all: Newbies (and others!) may find useful the R Reference Card made available by Tom Short and Rpad at http://www.rpad.org/Rpad/Rpad-refcard.pdf or through the "Contributed" link on CRAN (where some other reference cards are also linked). It categorizes and organizes a bunch of R's basic, most used functions so that they can be easily found. For example, paste() is

Hi Folks, I've got a question concerning the calculation of the Schwarz-Criterion (BIC) done by summary.regsubsets() of the leaps-package: Using regsubsets() to perform subset-selection I receive an regsubsets object that can be summarized by summary.regsubsets(). After this operation the resulting summary contains a vector of BIC-values representing models of size i=1,...,K. My problem

Dear R-list, I apologize for my many emails but I think I know how to desctribe my problem differently and more clearly. My question is how to compare linear models with intercept and those without intercept using maximizing adjusted R^2 strategy. Now I do it like the following: > library(leaps) > n=20 > x=matrix(rnorm(n*3),ncol=3) > b=c(1,2,0) > intercept=1 >

Hello, I have a question about doing ALL possible subsets regression with a general linear model. My goal is to produce cumulative Akaike weights for each of 7 predictor variables-to obtain this I need R to: 1. Show me ALL possible subsets, not just the best possible subsets 2. Give me an AIC value for each model (instead of a BIC value). I have tried to do this in library(RcmdrPlugin.HH),

Hello dear R-help members, I recently became interested in using biglm with leaps, and found myself somewhat confused as to how to use the two together, in different settings. I couldn't find any example codes for the leaps() package (except for in the help file, and the examples there are not as rich as they could be). That is why I turn to you in case you could share some good tips and

Dear UseRs, I wanted to know that i have been using "leaps" for the proper models selection for my work. I read so many articles from internet which categorically outlined that "leaps" command for model selection should never be used as its not efficient. Moreover, as a matter of fact, i personally noticed that the accuracy of "leaps" package is very much

Full_Name: Thomas Langhans Version: 0.65 OS: Solaris 7 Submission from: (NULL) (129.217.131.31) I tried to install the package "leap" on our Sun Enterprise 400 running Solaris 7, but it fails: cause the g77 doesn't compiles the fortran-sources properly, I translated them with f2c to c-source. Running R INSTALL produces the following message: Installing package `leaps' ...

Hi, I used the bic.surv function, S-PLUS functions developed by Chris Volinsky http://www.research.att.com/~volinsky/bma.html, without problems with S-PLUS. I have to use it with R but I am face with a problem: this function call a fortran routine named "leaps" (answer <- .Fortran("leaps", arguments)). I loaded the leaps library, and the leaps function work well with my R,

Hello I am trying to use all subsets regression on a test dataset consisting of 11 trails and 46 potential predictor variables. I would like to use Mallow's Cp as a selection criterion. The leaps function would provide the required output but does not work with this many variables (see below). The alternative function regsubsets should be used, but I am not able to define the function in

Hello guys, I am a total newbie on R, having downloaded it, read the documentation and started playing with it right now. My general question is what 'lr' model can be used for doing a linear regression on points that have a variance associated with them (ie. Monte Carlo simulation results). Actually my Data sets look like: Timestep Energy Variance_of_the_Energy 0.0005 -14.876840

I have problems with Rpad and R 2.10.0 (Windows XP and Windows 7, browser is Firefox) Just starting Rpad by library(Rpad) Rpad() opens the browser and displays the .html files and the .Rpad files in my home directory, but these files do not have links and are not clickable. Doing the same in R 2.9.2 gives clickable links in the browser. Furthermore, in both cases an empty graphics window

Now, on the server I can start the http://localhost/Rpad homepage, I can click on and browse the three examples

Hello, I have a question about Rpad Server Installation on Windows XP. Here is a guide http://www.rpad.org/Rpad/ServerNotes.html and I have been reading this more than ten times to figure this out, but still having trouble executing a Rpad website properly. Problem: for example, if I go to http://loclhost/Rpad/example1.rpad, I can see the whole website with the page loading sign staying on

Hi, this is Charlie. I have installed the Rpad on my server (using Fedora Core 6 with httpd2.24-2, mod_perl 2.0.2-6.1, perl 5.8.8 from RPM). When I access to the Rpad (through http://localhost/Rpad/basehtml), it shows me the main page as normal, however, problems occurs when I am testing the examples. It shows me a long message like: ----------------------------------------- #!/usr/bin/perl -w

Dear Rpad-users, currently I am setting up a web page using Rpad (www.rpad.org). But I have a problem with generating dynamic html-output in the Rpad chunk.
