Hi, There seems to be a problem with the power-operation of the form c(..., -a, ...)^x.yyy Four code examples for the same calculation, which perform differently: -3^3.2 Result: [1] -33.63474 c(-3,6)^3.2 Result: [1] NaN 309.0893 But: c(-3.62,3)^3 Result: [1] -47.43793 27.00000 I can reproduce NaN even in the following calculation: c(-3,6)[1]^3.2 Result: [1] NaN but c(-3,6)[2]^3.2 Result: [1] 309.0893 Does anybody know this problem and a solution to it...

...e ayuden mucho en la web. Estoy haciendo calculos por grupos con data,table. Tengo un archivo (zp.res) con tres columnas que clasifican los datos (sol, con, dia) y una columna de datos numericos (media), de la siguiente forma: sol con dia media 1: con 0 1 -22.6 2: con 0 1 -36.6 3: con 0 1 -35.6 y quiero calcular el promedio de "media" (la col 4) agrupando con las variables sol,con,dia. Lo hago de la siguiente forma: med <- zp.res[, mean(media), by="sol,dia,con"] cuando reviso "med" esta todo bien, se han calculado las medias...

Hi all, I wondered whether anyone has some advice on a stats-related 'sanity check', as I ran a nonparametric multivariate test (mulrank function as decribed by R. Wilcox, 2005) on both systems, but got different results (please see below for the system-specific outputs)! The functions I used are attached as well. Any advice would be much appreciated! Thanks in...

Hello R users, is there a possibility to get the relativ maximum of a matrix? To get the absolut maximum I use max(matrix) For example: The absolut maximum of this matrix is 6[3,6], but the relativ maximum is 6[3,6] and 4[7,6], because both values are the highest value in comparison to their eight neighbours values. [,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [1,] 1 1 2 2 2 1 1 2 [2,] 1 2 3 3 3 4 4 3 [3,] 3 3 3...

Hello, I have two data. x<-c(1, 2, 3) y<-c(4,5,6) How do i create matrix of 3 by 3 from this two, such that (1,4) (1,5) (1,6) (2,4) (2,5) (2,6) (3,4) (3,5) (3,6) I tried some thing like this: xy <- as.data.frame(c(0,0,0), dim=c(3,3)) for(i in 1:3) for(j in 1:3) xy[i][j]<-c(x[i],y[j]) but i got errors..!!!! a...

i think our strategy for privsep is to just keep portable sync'd closely with openbsd's tree, even though things will be broken wrt privsep for many platforms. then we just get primary one's working and work out issues as we go along. i'll start to work on sun and hp-ux again tomorrow.

...tcars$gear, row.vars = c(2, 4), dnn = c("Cylinders", "V/S", "Transmission", "Gears")) print.default(tmp) To get what you are looking for, you will need to intercept write.ftable with, for example, trace(write.ftable, exit=recover) then do 3 tmp.latex <- latex(t(x)) print.default(tmp.latex) Now open up t.latex and prepend \documentstyle{article} \begin{document} and append \end{document} then latex it. This gets you close to what you want and you can work with the generated t.tex file to get the rest of the detail. Or you can w...

Hi, suppose I have a matrix (or dataframe) as a result from subsetting. mat <- matrix(1:20,ncol=2) mat[c(3,6,9),] <- NA cc <- complete.cases(mat) sub <- mat[cc,,drop=FALSE] sub <- sub * 2 #some caluculations with sub. now I would like to expand sub somehow so row 3,6, and 9 would be filled with NAs but the rest should be in place again. Is there a simple function for this? merge is not an...

Hi , I am new to R . I am facing difficulty how to make pairwise comparisions. For example. I have a file which looks like below a b c d x 3 6 7 6 y 7 8 6 5 z 5 4 7 8 Here I need to look for the each pairwise comparisions (ab,ac,ad,bc,bd,cd for each row) For instance ,looking at first row, for x i need to look for ab values and take the min(3,6) >5 ,if its satistfies the count should be noted, (now count is 0), bc values ,min(6,7)...

virt-v2v moves guests, it doesn't clone them. Therefore we should try to preserve the VM Generation ID (genid) as much as possible. This has the ability to read the genid from VMware VMX files and libvirt XML (but note RHBZ#1598348). It can also write the genid to libvirt (‘-o libvirt’, ‘-o local’) and QEMU (‘-o qemu’). We a...

Hi Fellows, I am writing a pass that requires the DominatorTree pass. In the runOnFunction of my own pass, I call llvm::SplitBlock to split a block (%for.end) at it's first insert point. Then, when I dump my dominator tree immediately after, I can see the newly split %for.end.split, but its DFSNumIn and DFSNumOut are not properly updated in llvm::SplitBlock (i.e., still the initialized -1). At the same time, the DT->dump() results also show that DFSInfoVal...
