I have to perform ANOVA's on many different data organized in a dataframe. I can run an ANOVA for each sample, but I've got hundreds of data and I would like to avoid manually carrying out each test. in addition, I would like to have the results organized in a simple way, for example in a table, wich could be easy to export. thank you for assistance simone

With version 8 of acrobat reader, it is now possible to have 3D in PDf documents. Does it exist already an R package who manage to produce 3D plots which can be saved as interactive 3D graphs in a PDF file?

Hello, I need to extract sequences from an ordered vector. For example, if a<-c(1,2,3,6,10,11,13) I need to get the followings 4 vectors (1,2,3),(6),(10,11),(13) Thank You -Bruno ------------------------------------------------------ Leggi GRATIS le tue mail con il telefonino i-mode? di Wind http://i-mode.wind.it/

Hello my problem is the following: I have a matrix A and a vector B which contains as many rows as A. I need to build a matrix C which contains B[i]-times the row A[i,] and this for each line of A. if for example A is [1] [2] [1] 8 9.4 [2] 4.2 1.1 and B is (3,1). Then C will be: [1] [2] [1] 8 9.4 [2] 8 9.4 [3] 8 9.4 [4] 4.2 1.1 I have some

Hallo, Im trying to find out how to tabulate frequencies of factors when the data have a frequency variable. e,g: i<-rep(1:5,2) j<-rep(1:2,5) N<-10*i+j table(i,j) gives a table of ones as each combination occurs only once. How does one get a table with the corresponding N's? Thanks! Gerrit. -- Gerrit Draisma Department of Public Health Erasmus MC, University Medical Center

thank you to both Adaikalavan and Patrick. on the basis of Adaikalavan example this is an example that point out my problems. >log_raise=function(num, exp, base){return(log(num^exp,base))} I would like to have optional fields, so some settings to be default parameters; if I declare the function as above the operator must of course input all the variables. Finally I could fix as follow.

I've realize the follow situation: the phone A call the phone B, the phone B park, throgth the application map, the phone A, the phone B call another phone C, the phone B, througth the application-map, transfer the phone C to the phone parked A.

Some questions: * why call it 0.8.8, when 0.8.7 was not yet released? * CHANGES file miss some changes from previous version, e.g. the new pulseaudio plugin replacing polyp; * what about a longer rc period? It's only less than 1 hour (and the previous release was over 2 year ago); * what about merging some fixes in the trac ( https://trac.xiph.org/report/13 ) before the release?

Dear Partecipants to the list, I am Enrico Foscolo, a student of the Faculty of Statistics, University of Bologna, and I am interested under consideration of the search of zeros of one function. I would want to write a code using the software R. I have already read the book "Computing the Zeros of Analytic Functions" (P. Kravanja and M. Van Barel, 2000) that speaks about this problem,

Hi, We''re going to use in our product the Xen 3.0 tarball (freeware) downloaded from the link http://www.xensource.com/download/dl_304tarballs.html, in order to use this SW we need to know some information that I hope you can provide me: 1) Does the Xen 3.0 tarball contain any kind of encryption ? 2) Is it possible to re-distribute the product or an agreeement is required ? Thank you

Hi R-ers, I'm wondering if anyone has investigated a method for embedding audio files in R graphs (pdf format), and allowing their playback to be triggered interactively (by clicking on a graph element for instance). I know how to do this in latex pdfs with the multimedia package, but it seems that R would provide a more appropriate platform for many reasons. Thanks for any help you

Hi. That's my first post. it's driving me crazy. I'm trying to get dovecot working with vpopmail on Openwrt, an embedded linux-like OS for some routers . So actually my aim looks like get dovecot working with little hardware resources (32 MB of Ram, 8 MB of disk mem.) I've cross compiled it well(it looks like). the login against vpopmail works. using mmap it cannot even select

Folks, I'm writing a gui wrapper around RODBC (having abandoned RMySQL) and some custom analysis scripts. I'm hoping that I could get some advice. All of my users will have access to a database server. I am going to limit their access to certain databases--a sizeable warehouse in a SAN, and then smaller storage that they can use for temp files and personal tables. I want to present

Hello everybody, we were running into trouble after upgrading our samba PDC to a new hardware (and a new debian release). Before the upgrade we used 3.0.22 on a debian sarge machine without problems. Moving the installation to a new machine with debian etch (amd64, samba 3.0.24-6etch4) worked good at the first look. A closer look shows the following problems: - a domain member server (samba

I have some doubts about the validity of my procedure to estimeate linear contrasts ina a factorial design. For sake of semplicity, let's imagine a one way ANOVA with three levels. I am interested to test the significance of the difference between the first and third level (called here contrast C1) and between the first and the seconda level (called here contrast C2). I used the following
