Re: [R] transposing data

Ah, this clarifies what the reshape documentation referred to as the "timevar" argument. I'd gone wrong because I'd been confusing reshape's functionality with that of SPSS's cassestovars command, which is where I'm coming from. Your recommendation seems to lead to exactly that I was lookin

Re: [R] transposing data

Frank - I think you need to create a composite time variable to do what you want to do: exp1.r5$key = with(exp1.r5,paste(CannonAngle,CannonOriB, CannonOriR,nRedPelelts,TargetColor,tbearing,sep='.')) exp1.r5.use = subset(exp1.r5,select=-c(CannonAngle,CannonOriB,

[R] transposing data

Hi. I have repeated measures data of the form where each observation is a trial, and trials are grouped by subject, and variables encode whatever level of a factor was present during that trial, and the dependent variable is response time (RT). I want to transpose the data to a form suitabl

[R] Transposing Data Frame does not return numeric entries

I have a species as rows and sites as columns matrix. I would like to tranpose this matrix so that I can do an NMDS analysis with the vegan package. I have used y <- t(x) and it indeed transposes the matrix, but it changes the whole make up chr [1:193, 1:288] "oligocha" "0" " 0" " 0" " 0" "0"
