CFD Plots in R and Other Things
Dear All,
I am getting some data from fluid dynamics simulations (air mixing in
a pipe, 2D axial symmetry, geometry described by a radial coordinate r
and an axial coordinate z) which I'd like to plot and analyze with R.
Think about slicing the cylinder along its axial direction to get a
set of cross sections which are orthogonal to the z axis.
For each section, I have a set of velocity

support remotely mounting disk images in p2v
Figure I'd share the latest revision to p2v I had regarding $subject.
The patch now applies against HEAD and compiles fine. I was able to update
the package on the client and run virt-p2v, though have yet to do a full
end-to-end verification
Most likely a little more work is needed to tidy up some edge cases and fully
flush things out, but the majority of the work should be in place.

When rsync is deleting the files in a directory with 12,000+ files

removed in the mirror), it stops outputting results in the middle of

Numerical stability in chisq.test
The chisq.test on line 57 contains following code:
STATISTIC <- sum(sort((x - E)^2/E, decreasing = TRUE))
However, based on book "Accuracy and stability of numerical algorithms" available from:
http://ftp.demec.ufpr.br/CFD/bibliografia/Higham_2002_Accuracy%20and%20Stability%20of%20Numerical%20Algorithms.pdf
Table 4.1 on page 89, it is better to sort the data in increasing order than in decreasing order, when the data are non-negative.
An example:
x = matrix(c(rep(1.1, 10000)), 10^16, nrow = 10001, ncol = 1) # We...

The book covers a broad range of mathematical models including
statistics, ordinary and partial differential equations, 3D FD- and
FE-models in CFD and structural mechanics etc. It includes an
introduction into R and 31 R programs that can be downloaded in the
