Dear All: I would like to center the data in 'x' by 'group'. The following code scale the data and I have not been able to figure out how to change it so I get the centered data. x <- c(1, 2, 3, 4, 5, 6, 7, 8) group <- c(1,1,1,2,2,2,2,2) unsplit(lapply(split(x,group),scale),group) I would appreciate your help.

Hi All: I have to compute bootstrap confidence intervals, the statistic (incremental cost effectiveness ratio) is computed from two samples (intervention and control) of different sizes. All the bootstrap functions that I have seen use one dataset as argument. I may go ahead and get the desired number of bootstrap replications separately. I would appreciate if you could point me to a source of a

...ossible to transform one of the residual measures into something reasonably 'normal' while retaining information from the residual so I could compare between models (obviously I could blom transform any of the measures, but then I'd always get a standard normal)?

Dear All: lme(sbp ~ cengirth, data = family, random= ~ 1 | familyid) converges but lme(sbp ~ cengirth, data = family, random= ~ cengirth | familyid) does not. I get the following message: Error in lme.formula(sbp ~ cengirth, data = family, random = ~cengirth | : iteration limit reached without convergence (9) The data has 488 rows and 154 familyid levels.

Greetings Richard, Thanks for the pointer. It was helpful. (Note: We have 2 physical machines, one is p2v machine & the other is conversion server. Both the machines have been updated with "*yum install qemu libvirt-client virt-manager virt-viewer guestfish libguestfs-tools virt-top*") We have couple of questions for the exact functioning of virt-p2v: 1. We are unable to

Hi guys, I am compiling some programs with clang which use a couple of libraries. When I compile with the command - "clang -O2 -I. -o hello -ldl -llttng-ust hello.c tp.c", it goes successful. My aim is to get the bitcode for these programs but if I try to generate the bitcode with -emit-llvm option, it produces linking issues as follows : (also at - http://pastebin.com/zkmL2SAH)

Thanks, Bimal PS-yes, I know that if my collaborator just used R, he could send me just the model as an Rdata object. That is not going to happen in this instance.

I am producing 2X2 correlation matrices by a class variable. I need to extract a vector of correlation coefficients only. I am doing that in a loop (see below) but I am sure there would be a simpler way. Please help! > by(d1[,c(2,3)],d1[,1],cor) d1[, 1]: 1 c e c 1.0000000 0.1972309 e 0.1972309 1.0000000

Hi All: I would like to generate a binomial random variable that correlates with a normal random variables with a specified correlation. Off course, the correlation coefficient would not be same at each run because of randomness. I greatly appreciate your input. Ashraf

I am trying to find out if R can recognize specific criteria for removing rows (i.e. a prexisting function) I have a matrix myMatrix that is 12000 by 20 I would like to remove rows from myMatrix that have: -999 across all columns -999 across all columns but one -999 across all columns but two -999 across all columns but three -999 across all columns but four -999 across all columns but five

Hi guys, I am following this[1] tutorial to install clang. However, I have made a small change in the configure command, and I am running it with '--enable-optimized' option to avoid the debug build. I am getting the errors (given at the end) related to *undeclared identifiers '__NR_*'*. Can someone please provide some input about how to tackle this issue? On my other machine, I

Hi All; The following question is directed more to statisticians on the list. Suppose I have a normal random variable. Is there a transformation that I can apply so that the new variable is slightly positively skewed. I greatly appreciate your help. Ashraf

Dear All: I have been struggling to run the conditional logistic regression on a dataset. I am using clogit function in survival package. Here is how the data is generated. I tried to shorted the data by using the second count variable but still the clogit did not run. Why I am not able to run clogit on my dataset. I appreciate any input.
