Error in documentation for ?legend
To whom it may concern: The help page for ?legend refers to a `title.cex` parameter, which suggests that the function has such a parameter. As far as I can tell, though, it doesn't; here's an example: > plot(1,1) > legend("topright",pch=1, legend="something", title="my legend", title.cex=2) Error in legend("topright", pch = 1, legend =

Using Xen Virtualization Environment for Development and Testing of Supercomputing and High Performance Computing (HPC) Cluster MPICH2 MPI-2 Applications
Dear All, I have created a virtual high performance computing (HPC) cluster of 6 compute nodes with MPICH2 using Xen-based Fedora 11 Linux 64-bit paravirtualized (PV) domU guests. Dom0 is Fedora 11 Linux 64-bit. My Intel Desktop Board DQ45CB has a single onboard Gigabit LAN network adapter. I am able to bring up the ring of mpd on the set of 6 compute nodes.

Calculating the power of a negative number
Hello, I use R a lot, one thing bugs me is that when I try the following > x<- -8 > x^(1/3) [1] NaN However, it is fine with -8^(1/3). Priority goes to the power. Can you help me out for this?

How to Backup and Restore MBR within Logical Volumes?
Hi All, I have several Xen virtual machines within logical volumes using LVM2. I did not use disk images for performance reasons. Conventionally, if I want to clone my virtual machines, I have to dd the LV to an image file. But this consumes a lot of time and harddisk space. So, instead of doing that, I want to use losetup and kpartx with my logical volumes, which contain operating systems of

Tab-delimited AOV summaries
Hello, I am trying to print out ANOVA summaries --- as returned by summary (aov(...))--- in tab-delimited format, either to a file or to the console, but so far I haven't been able to figure out a solution. My particular ANOVA has repeated measures, so it is an instance of class aovlist. Can anyone offer any suggestions? I am relatively new to R, so please forgive me if I am missing

Metropolis-Hastings Markov Chain Monte Carlo in Spatstat
I'm testing some different formulations of pairwise interaction point processes in Spatstat (version 1.11-6) using R 2.5.0 on a Windows platform and I wish to simulate them using the Metropolis-Hastings algorithm implemented with Spatstat. Spatstat utilizes Fortran77 code with the preprocessor RatFor to do the Metropolis-Hastings MCMC, but the Makefile is more complicated than any I have

Bivariate normal regression in R
Hello everyone, I need to fit a bivariate normal regression model to a dataset where the same covariate (say, X) influences two separate but correlated responses (say, Y1 and Y2). So, the bivariate model would look like : Y1 = a1 + b1*X + e1 Y2 = a2 + b2*X + e2 where e1 and e2 are error terms which can be correlated. Is there any package in R which can help me fit this model ? Any help will be

R loop function in Tableau
Hi R helpers, I hope this email finds you well. I am having trouble with R loop function in Tableau. Please see the attachment of a simple dataset. The problem is to test whether the value of columns is match. Because Tableau do not have iteration function, I coded ?if statement? in Tableau to realize the function, which is slow if having huge amount of data. I wonder to integrate

enterprise scale redundant Solaris 10/ZFS server providing NFSv4/CIFS
We are looking for a replacement enterprise file system to handle storage needs for our campus. For the past 10 years, we have been happily using DFS (the distributed file system component of DCE), but unfortunately IBM killed off that product and we have been running without support for over a year now. We have looked at a variety of possible options, none of which have proven fruitful. We are
