Hello! I have a dataset with variables in string format (ages class and sex) which I want to recode as numerical variables. How can I accomplish this? Is there any way to do that automatically? Could someone help me? Thanks in advance, Marcos -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read

Date: Wed, 19 Sep 2001 15:19:07 -0300 I know this is a basic question, but I've never used the 'ts' package and I'm having some problem with it. If I type, for example: >fit1<-arima0(x , ....

Hello all, I have the square symetric matrix A: 2 1 1 1 2 1 1 1 2 My first question is what is the easiest way to enter this matriz in R? Second, matrix A has an eigenvalue with multiplicity 2, in this case, how could I find the two related ortogonal eigenvectors given below by R, without the help of R, I mean, I want to know how R calculate this eigenvectors related to the same eigenvalue.

This should do what you want: # construct a data.frame d L3 <- LETTERS[1:3] str(d <- data.frame(cbind(x=1, y=1:10), ch=sample(L3, 10, repl=TRUE))) d # replace y-value in d, where y=5 d$y[d$y==5] <- 100 d Regin -----Oprindelig meddelelse----- Fra: Pesl Thomas [mailto:thomas.pesl at arcs.ac.at] Sendt: 29. august 2000 14:02 Til: R-Help (E-Mail) Emne: [R] short way i want to replace

Hi all! I am fitting a Poisson model, using the following command: > fit2<-glm(canc~id1+year1+time+lnpa,family=poisson) where 'id1', 'year1' and 'time' are factors. I defined them with: > id1<-C(factor(id1), treatment) and 'lnpa' is a continuous variable. The 'summary' function gives me all the effects estimates, that is, for id1, I

Hello list! I have a problem with the function 'persp'. I have a data set with the variables X -> The X coordenate of the insect Y -> The Y coordenate of the insect deep-> how deep the insect buried into the soil. I would like to have a plot with a surface simulating the way the insect buried. Is it possible? If I type persp(x,y,deep) R gives me this error message Error in

I have had the same problem and I wrote this function rmulti <- function(n, size, p) { NrDim <- length(p) if(NrDim<2) stop("The simulated variabel has to be at least 2-dimensional") res <- matrix(data=NA, nrow=n, ncol=NrDim) p <- p/sum(p) TempSize <- size for(i in 1:NrDim) { TempP <- p[i]/sum(p[i:NrDim]) TempBin <- rbinom(n=n, size=TempSize,
