Re: [R] Variance Calculation in R

Then you can try: rownames(data.matrix) <- as.character(data.matrix$ProbeID) data.matrix <- data.matrix[-1] as.matrix(apply(data.matrix1, 1, var)) or out <- apply(data.matrix1, 1, var) data.frame(ProbeID = names(out), Variance = unname(out)) Works for me On 02/03/2008, Keizer_71 <[EMAIL PROT

Re: [R] Variance Calculation in R

Hi Henrique, It is definitely better, but it doesn't show me the ProbeID which identify the probes name Here was the result when i export to excel with your code. "Variance" 1 2.425509867 21.6216446425273 any suggestions? thanks, Kei Keizer_71 wrote: > > Hello, > > Thanks everyon

Re: [R] Variance Calculation in R

Try this: write.table(cbind(data.matrix[1], Variance = apply(data.matrix[,-1], 1, var)),file='file.xls') On 02/03/2008, Keizer_71 <[EMAIL PROTECTED]> wrote: > > sorry...in step 4-i need the R code to output in this format when i export > to > excel. > > ProbeID Variance > 1

Re: [R] Variance Calculation in R

sorry...in step 4-i need the R code to output in this format when i export to excel. ProbeID Variance 1 224588_at 21.58257457 thanks Keizer_71 wrote: > > Hello, > > Thanks everyone for helping me with the previous queries. > > step 1: Here is the orginal data: shor
