I want to load many files in the R. The names of the files are "Sim1.txt", " Sim2.txt", "Sim3.txt", "Sim4.txt", "Sim5.txt" and so on. Can I read them at one time? What should I do? I can give the same names in R. Thanks. For example: > tst=paste("Sim",1:20,".txt",sep="") # the file names > tst [1]

Dear list users, I have trouble with covariance analysis. I measured nitrate concentrations in the soil (NO3) and the percentage of legumes (LEG, continuous), affected by 2 different CO2 concentrations (CO2, discrete). I suspect that CO2 has an effect on LEG and NO3, but also that LEG has an effect on NO3, so this is the formula I wrote to test this: NO3 ~ CO2 + LEG + CO2:LEG Will LEG be

something like ... > x<-c(1,2,3,0,5,6,0) > is.na(x[x==0])<-T > x [1] 1 2 3 NA 5 6 NA ~~~~~~~~~~~~~~~~ Robert Kinley ~~~~~~~~~~~~~~~~ [[alternative HTML version deleted]]

Hello, I am working with a dataset with three variables and one binomial parameter. The glm function provides coefficients for these three variables, e.g. -1.5 | 27.2 | -2.9 If I'm not mistaken, $fitted.values gives me an estimate of how likely my parameter is to be true/1 . I would like to apply these coefficients on other variables to predict the binomial parameter but I'm not sure how

I've installed Darwine on an iMac. As per the documentation, I have attempted to run winecfg to set the various configs. But I cannot get it to display. The error log says that it attempted to create a window, but no driver found. Since I can't config, I can't set a driver. Any ideas?

I really like RStudio ... ... but I wish it wouldn't automatically reload the last .RData it had. Anyone know how to fix this ... ? Also - does anyone know is there an Rstudio-user email-list forum thingy out there ? ta. Robert Kinley [[alternative HTML version deleted]]

platform: R 2.14.2 - Windows XP - Rstudio When I use cat() or print() in a script, the output text is of course mixed up with the lines of the script. I can sink() the output to a textfile and then play the file back at the end of the script, but that's not really what I'm after. It would be nice if the lines of text output could appear in a separate window, in the same

Hi I'm having difficulty working out how to get what I think is the appropriate partitioning of variability in a repeated measures setup. I have G=5 treatment-groups, each containing n=6 subjects, and a response is measured on each subject on t=4 occasions. I think the anova degrees of freedom should partition as follows - Between-subjects: G*n-1=29 [ between-groups: g-1 = 4 ,

hi I've used R for many years on windows machines, but have now acquired an Asus eee 1000 linux machine. In order to get the best out of the machine, I used the 'pimpmyeee.sh' script, to get the full KDE desktop. The version of Linux is Xandros, which I believe is a close relative of Debian, but sadly I have only a nodding acquaintance with Linux at present. Naturally I want to

I have R v2.0.1 already running on the machine in question; a fairly generic Fedora Core 3 machine. I am trying to build the new version 2.1.0 and have not been able to troubleshoot the problem I encountered. I'm hoping someone else has seen it and can suggest a troubleshooting avenue to me. The build succeeds, both from the source RPM and from the tarball. I believed I had all the build

Hi does anyone know of any R functions or packages for the following :- . generating cube plots for displaying the results from a response surface experiment design . generating ternary plots from a mixture design . tetrahedral plot or quaternary plot for displaying results from a four factor mixture experiment thanks Bob Kinley [[alternative HTML version deleted]]

Hi folks I have inherited a package which was created before release 2.10 and I need to have it working in release 2.12 There is a folder containing the Man, Data and R subfolders, and the description file, and there is also the corresponding zip file. I can install the package from the zip file, but when I try to load it I get the message :- Error: package was built before R

{ I think this message got rejected at the 1st attempt - trying again} R 2.15.1 , windows XP I have a very non-stationary bivariate time-series - say {xt,yt} t=1 ... lots. I want to do a bivariate density contour-plot of the whole series and then step through the series 1 second at a time plotting that second's {x,y} subset on top of the contour plot and losing the previous

Hi For bureaucratic reasons beyond my control I need to rewrite an R function (for producing operating characteristic curves) as an Splus function ( version 6 , windows XP ). The R function makes extensive use of the fact that the student's t distribution function pt() has a non-centrality parameter built in ... sadly that parameter is not present in the Splus pt() function .

Hi folks Seems really simple but run out of ideas: 1. Used Redhat 9 Packages for Asterisk 2. Zaptel one didn't work so recompiled zaptel from cvs against my kernel 2.4.20-8 3. Compile is fine no depmod problems/ugly message etc. 4. lsmod: wcusb 20064 0 (unused) wcfxo 9376 0 zaptel 179168 0 [wcusb wcfxo] 5. start up messages on

Hello, I am trying to install R/Bioconductor on a G4 Mac running OS X. I have successfully installed R so that a command window opens, but installation of the downloaded Bioconductor package is giving me trouble. After copying/pasting the Bioconductor installation script in to the window and typing getBioC(), I get the following error message. "Error in getBioC(): R not currently

Hi everyone, I'm taking a course in statistics as part of my doctoral program in education at the U. of Minnesota, USA. I found R via Rpy, a python module that makes it possible to use R from python scripts. The instructor refers to SPSS a lot and that seems to be the standard stats tool around here. But being more of a Unix guy and not intimidated by programming, I'd like to see if I
