I've written a package to assist with using R in Hadoop Streaming. The main point of the package is to help make command-line runnable RScript files. I'd like to provide a demo RScript file, a demo data file (e.g. a plaintext file, not something already processed by R) , as well as demo bash shell scripts that demonstrate how to run the job from the command line and in a Hadoop

...to run just a simple ANOVA nanalyses. I dowloaded R version 2.10.0, and it seems I have problems with the script. I don?t know what to do, I?ve already change the languages, be sure of being working in the correct directory and doesn?t work the script is: #1. example data01<-read.table("ch01.txt",header=T) names(data01) attach(data01) FERTIL<-factor(FERTIL) model01<-(YIELD~FERTIL) summary(model01) anova(model01) all my classmates, even those with a mac operator, wrote the same, and it worked. When copying the script in the R console, it seems that there is a problem...

Hello, I'm trying to use libvirt as a non-root user to obtain statistics on the CPU usage by VMs using the Python API. I'm performing basically the following steps: import libvirt conn = libvirt.openReadOnly(None) dom = conn.lookupByUUIDString('268e38ea-1bc7-41e4-c19e-8eff682e58e4') dom.getCPUStats(True, 0) However, they result in the following error: libvir: QEMU Driver

Hi, every body! I am a new comer for R, so my question would unavoidablely sounds stupid. Sorry! In my experiment, there are two type of soil ( soil F and soil D), each half of them were subjected to steam sterilize (result in FS and DS soil). A equal volume of soil from two of the four soil types (F, D, FS, DS) were mixed as follows: F+F, F+D, F+FS, F+DS, D+F, D+FS, D+DS, FS+DS (eight

...nst one file ch02.pdf, and it almost contineously corrupts, I checked in a hex editor and there are some differences. Yet the problem is that its not read the same way each time. The md5 changes and oddly enough this seems to affect some files more than other. Ironically ch02.pdf is eBook on Samba, ch01, and ch03 almost never seem corrupted I've moved both of the files to see if directory depth has anything to do. And it doesn't I also checked another machine, now the other machine running the same version of samba (Samba 2.2.3a [Debian Version]), yet diff versions of debian (stable vs. te...

Hi everyone, I have a licencing question : do one need to buy CAL for every user in a Samba4 domain when there is a Windows Server as a domain member, knowing that the Windows server will be accessed using SMB by Windows workstations? As per http://www.samba.org/samba/docs/using_samba/ch01.html and many other web sites, one of the main advantage of samba is that no user CALs are required. And I think the case is clear when there are only Windows workstation and one samba server. However, in the case where I have a Windows member server joined to the Samba4 domain, do I need user CAL...

Hi, I'm trying to fit a model using variance components in R, but if very new on it, so I'm asking for your help. I have imported the SPSS database onto R, but I don't know how to convert the commands... the SPSS commands I'm trying to convert are: VARCOMP RATING BY CHAIN SECTOR RESP ASPECT ITEM /RANDOM = CHAIN SECTOR RESP ASPECT ITEM /METHOD = MINQUE (1) /DESIGN

Dear List, I am new to TS-Modeling in R. I would like to fit an ARMA(1,1) model for a balanced panel, running Y on a full set of unit and year dummies using an arma(1,1) for the disturbance: y_it=unit.dummies+yeardummies+e_it where: e_it=d*e_it-1+u_it+q*u_it-1 How can I fit this model in R? arma() does not seem to take covariates (or I don't understand how to specify the function so that

Dear R People: Sorry for the off-topic. Could someone recommend a good reference for using the EM algorithm on mixed models, please? I've been looking and there are so many of them. Perhaps someone here can narrow things down a bit. Thanks in advance, Sincerely, Erin -- Erin Hodgess Associate Professor Department of Computer and Mathematical Sciences University of Houston - Downtown

Dear All I would like to draw a picture with the density curve of a normal distribution over a histogram of a set of random numbers extracted from the same normal distribution. Is that possible? Thanks in advance, Paul

I like what smooth.spline does but I am unclear on the output. I can see from the documentation that there are fit.coef but I am unclear what those coeficients are applied to.With spline I understand the "noraml" coefficients applied to a cubic polynomial. But these coefficients I am not sure how to interpret. If I had a description of the algorithm maybe I could figure it out but as it

someone have been installed Asterisk (Trixbox) on VirtualBox which is installed on a Linux host (Ubuntu server 10.04 specifically). I want to know if it is convenient or not, and the reaseons if i should on shouldn't do it. Thanks in advance.! -- Esteban L.

I tried to use LME (on a fairly large dataset, so I am not including it), and I got this error message: Error in lme.formula(formula(paste(c(toString(TargetName), "as.factor(nodeInd)"), : nlminb problem, convergence error code = 1 message = false convergence (8) Is there any way to get more information or to get the potentially wrong estimates from LME?

I have 2 questions on ANOVA with 1 between subjects factor and 2 within factors. 1.

Hello. As advised by Mick Crawley in his book on S+, I'm trying to use the lme function to examine a linear relationship between two variables measured at 60 locations in 12 sites, while taking account of any spatial autocorrelation (i.e. similarity in variation between the two variables that is due to site). I am using the function as follows:

Hello, I have an irregular time series of the form : Time Data Time1 Data1 .... 1 b 1 e 7 g 4 i NA NA 5 k NA NA NA NA ... (the columns have varying length of NAs after a certain point) Converting this to regular time series with Pastecs does not seem to work, when I see the entire data as a single series. So I remove

Thanks a lot for the quick answerd I received and that helped me to solve my first (simple) problem with the plm package. Unfortunatley, here's another one: I do not know why, but I'm unable to estimate a simple model in the form y ~ 1 + x When I try > zz <- plm(y ~ 1 + x , data=mydata) I obtain Errore in X.m[, coef.within, drop = F] : numero di dimensioni errato which means

Well, today, I feel like a real, old time sysadmin. Now, I didn't have to write a driver in assembly for the printer, but.... We got this huge, 44" HP Designjet z3200ps printer. Only supports Win and Mac. Fine, I hang it off of one of our servers on a subnet (at $0.96/foot paper, we're the only ones who print on it....). Then I'm thinking that all I really need is a .ppd. My
