I've looked throught the documentation, but cannot find any references to appending a persp plot. Thanks. Sincerely yours, Mark J. Lamias Statistical Consultant

Dear All, I am doing a performance study on Xen, and we are deploying Charm++ parallel runtime library as part of our applications. However, we observed a 20% slow down in Xen kernel that was not observed with MPICH. It is very important for us to understand why this overhead is happening. I am guessing that is caused due to the higher cost of system calls like fork and exec, since Charm++

Hi Lamia, Currently there is no direct InfiniBand access support in the Official Xen trees. You might want to have a look at our Xen-IB implementation. A preliminary version can be downloaded here: http://xenbits.xensource.com/ext/xen-smartio.hg Some information about its design and applications can be found here: High Performance VMM-Bypass I/O in Virtual Machines (Usenix 06), and A Case for

Hi all, I have another problem with starting domainU (xenolinux). I took me pretty much quite some time and i can not figure out why starting a new domain is failing. I will really appreciate if somebody can help me with this error.

Is there an equivalent in R to the crosstabs command S-Plus? I've been searching for a while and can't seem to find anything. Thanks. Mark J.

Hi, I am trying to convert a colleague from using SPSS to R, but am having trouble generating a result that is similar enough to a bootstrapped cox regression analysis that was run in SPSS. I tried unsuccessfully with bootcens, but have had some success with the bootcov function in the rms package, which at least generates confidence intervals similar to what is observed in SPSS. However, the

Dear All, I have been looking for resources on how to get Xen to work with infiniband. I do not have much experience with infiniband, or how to get it working on kernel, and how to configure xen to work with it. I would appreciate it very much if somebody can point me to some url or manuals to get the job done. Thank you, Lamia _______________________________________________ Xen-users

Does anyone know a command to obtain the expected values of residuals under normality? Better yet, is there a command to perform a correlation test for normality (not Shapiro-Wilk Test)? I've looked everywhere, and can't seem to find how to do this. Thanks. Mark J.

Dear List, This problem is more a statistic one than a R one. Any one can recommend me some references website or online paper on maximum likelihood estimation?I'm now working on that,while still doubt how to prove that the estimated parameters are normal distributed. Thanks for your time and help! Best, Ning

Hi, R allows me to run a one sample Wilcoxon test like this: wilcox.test(c(1,3.5,2.1,4,1.5,5), mu=2, exact=TRUE) The function 'wilcoxsign_test' from the package 'coin' should (I suppose) be able to calculate exact p values even if there are ties in the ranks. However, I couldn't find information on how to run a one sample test using 'wilcoxsign_test' like in the

Hi list, Could anyone recommend some good website for formatting R code? For example, when you copy paste R code to gmail and back to R, it loses its format, the dash symbol causes errors. I've had someone used it to format my code here on the list, but can't find it anymore. Mike [[alternative HTML version deleted]]
