Hi List, I want replace characters within a vector. Outside R I could use sed, but I'd like to automate it in R. For example vectorx xxxyyz xxxyyza xxxyyzzb I want to change to: vectorx aaayyz aaayyza aaayyzzb The obvious replace command only deals with whole data entries? Any hints would be appreciated. Thanks Herry

Dear useRs, I'm writing regular survey reports using Sweave. Each report has several sections along the lines of: \section*{Disease X} <<MapX,fig=TRUE,echo=FALSE>>= image(vectorx,vectory,matrixz) @ Notes with or without Sexpr{a}. \vfill \pagebreak \section*{Disease Y} <<MapY,fig=TRUE,echo=FALSE>>= ...etc. Often one or more of the diseases is not observed (all

Hello and sorry to disturb. I'm trying to plot the confidence intervals for the fixed effects of a lme. I want to obtain graphically, if it is possible, a bar with Estimate, upper and lower CI for each level of the factors. I know how to do for a lm model but for a lme one, I tried with plot(intervals(...)) and plot(ci(...)) from the gmodels package but it doesn't work well. Thanks

Good morning, I used in R contr.sum for the contrast in a lme model: > options(contrasts=c("contr.sum","contr.poly")) > Septo5.lme<-lme(Septo~Variete+DateSemi,Data4.Iso,random=~1|LieuDit) > intervals(Septo5.lme)$fixed lower est. upper (Intercept) 17.0644033 23.106110 29.147816 Variete1 9.5819873 17.335324 25.088661 Variete2 -3.3794907 6.816101 17.011692 Variete3

Hi, I want to generate a number of vectors and store them with different names, like this: x=1 while (x<100) { vector#x# = rnorm(100) x=x+1 } where each vector has, at its hand, instead of #x# a number which goes from 1 to 99. How can I do this? Thanks Gabriele Zoppoli, MD Ph.D. Fellow, Experimental and Clinical Oncology and Hematology, University of Genova, Genova, Italy Guest

Dear advanced statisticians, *******Objectif******** I try to set up linear models with mean as intercept: Answer: y Variable: x, as factor of two modalities: x(1), x(2). I would like to have a model as: y = mean(y)+A(i)+residuals, with i in (1,2) and A(1) coefficient for x(1) and A(2) coefficient for x(2). *******Trials in R******* ## Firstly: I write in R: >Model<-lm(y~x,Data)

Dear R-list, I'm experiencing some problems while using "strptime", which I don't understand. > str(natver) 'data.frame': 154 obs. of 8 variables: $ ID : Factor w/ 14 levels "AC","ALS","FA",..: 10 11 9 1 4 8 13 3 14 12 ... $ CdBMin : int 22 22 26 26 28 23 27 23 25 26 ... $ CdBMax : int 22 24 27 26 32 26 29 30 29 28 ... $

Looks like you need to pay attention to how you read in your data. In general, you should always execute one statement at a time until you know your script is working. All the errors after the first one are unhelpful to you or us. If you actually pay attention to what is in your horse.data data frame after you have read it in, the columns did not get separated out. The "csv" in in

Bonjour, Je cherche à installer le package odesolve du logiciel de statistique R sous Ubuntu Linux. C'est un package qui contient des fonctions appelant du code en Fortran.

Dear All, I am trying to convert to POSIXct after pasting a date and a time in character format with strptime. It is probably obvious but I don't understand why I get an error message after bsamp$spltime<-strptime(test,format="%d-%B-%y %H:%M") whereas I can get what I want if I do it in 2 steps and rbinding ? Thanks and best regards, Jean-Louis This is the R console output

Hi all, We are running a samba (3.0.14a-3 / sarge) server with windows 2000 Client.

Hi, As I can see in the last mailing list I am not the only one to get problems with ACL support in Linux. Whatever the samba version (2.2.4, 2.2.5) the main problem is how acl and extended attributes can be implemented fine in linux. I've installed samba on AIX systems where acl is implemented (native) and NT ACL works fine at each time (the only difficulty there is that nsswitch is not
