Adding per-panel text to panel strips in lattice xyplot
...e panel. For example I might panel on sex and
race, showing 3 randomly chosen time series in each panel and want to
add (n=100) in the bottom strip to indicate the 3 curves were sampled
from 100. Is there a not-too-hard way to do that?
I would like to do this both with and without groups= and superposition,
but especially with.
Thanks

two questions about PLOT
...lems
1) how to move one of the y-axis to be the right ? I tried to the
command"axis(2)",But I failed.
2) how to add the axis information correctly.Since I have use the cmommand
"axis(1,at=1:6,labels=gradeinfo$gradenam)"
but it seems that the correct information that I want is superposition
with the old axis information.What can i do ?

funnel shift, select, and poison

Does a call stop poison?
Whatever the decision is may be contradicted after inlining, so what
should such a call return? A superposition of poison and non-poison,
until the function is inlined? It's a serious question.

lattice histogram function and groups
...iable|individual+group)
I get six panels, one for each of individuals 1-3 in group A and one
for each of individuals 1-3 in group B .
What I want is three panels , one for each individual, but with A and B
paired in the same panel. I think the "groups="argument does this sort
of superposition for other lattice functions.
Thanks very much for any help.

"inside" argument in barplot
...t;inside" in the barplot function would be functional, cause I
could just add this curve to the actual barplot, but it seems like it is not
(not yet implemented). Argument "inside" would allow not to plot the line
dividing two bars and using a null color within these bars would allow
superposition with the actual bar plot and indicate the sample depth.
Do you have any suggestions or experience to share?

pairs(X,Y) analog of cor(X,Y)?
...e
plots of each X against each Y?
The formula method for pairs() is for a one-sided formula. As a
formula, I'm looking
for something like
pairs(math + read ~ antisoc +hyperact + income + educ, data=NLSY)
lattice::xyplot has an extended formula interface, but interprets '+' to
mean
superposition.

Overlaying lattice graphs (continued)
Dear R Users,
I recently posted an email on this list about the use of data.frame and
overlaying multiple plots. Deepayan kindly indicated to me the
panel.superposition command which worked perfectly in the context of the
example I gave.
I'd like to go a little bit further on this topic using a more complex
dataset structure (actually the one I want to work on).

Best Practices for Data Recovery for corrupted EXT2/3?

identical drive that I have been working on. But every time.. a fsck
destroys all the data (moves everything to lost+found) and nothing that I've
found is able to restore the dir structure... or allow me to superposition
any of the subdirs (such as /home/*).
I've tried testdisk, dd_recover, and Autopsy.. mounting and fsking with
alternate superblocks, all with no success.
I would like to retain file names.. as I see that SOME filename/dir structure
is intact when the fsck starts nuking all my files that d...

Indeed, this has now been well documented; I have called these constructions "Schr?dinger Facts", since they arise from a superposition of truths in the training data that collapse into an untruth when observed.

panel/prepanel for polar plots ala xYplot
...e
axes and labels, and (b) calls xyplot with panel.radplot,
prepanel.radplot, and radplot.superpose replacing the obvious things.
I am generating the "axes" (concentric circles and peripheral labels)
in panel.radplot, but this means that they are redrawn for each group
when there is superposition. Furthermore, there seems to be some
jittering, so besides inefficiency, the result is not crisp.
How are axes generated in xyplot? To do this correctly will I have to
go deeper and make a new version of trellis.skeleton or make a new call
to it? If I put the code into prepanel.radplot will...

QGA 1.0 is released
...QGA implements the Quantum Genetic Algorithm, as proposed by Han and Kim
in 2000, and is an R implementation derived from the Python one by
Lahoz-Beltra in 2016.
Under this approach, each solution is represented as a sequence of
(qu)bits. Simulating the quantum paradigm, these qubits are in a
superposition state: when measuring them, they collapse in a 0 or 1
state. After measurement, the solution's fitness is calculated as in
usual genetic algorithms.
The evolution at each iteration is oriented by the application of two
quantum gates to the amplitudes of the qubits: (1) a rotation gate

Hmisc xYplot

I am having trouble with a particular plot that I am trying to produce
using Hmisc's xYplot function. I've been using primarily lattice and
Hmisc packages for my plotting needs for the past few years, with great
success.
However, what I want to do now with xYplot is plot more than one data
trend in the same panel, much as I would use xyplot from package

As the traffic is flowwing as it should and with the information from tcpdump, i
don't think the problem comes from openswan which is the VPN software used here.
I think the problem relies in the superposition of virtual interface : tunnel0
on top of br0.

Floor1 doubts...
...which units?). As I haven't been able to find any reference to
this, I tend to believe that the conversion is made to p1/p0...
In the other hand, in "Improved Noise Weighting in CELP Coding of Speech -
Applying the Vorbis Psychoacoustic Model To Speex", it is said that the
floor is a superposition of the tonal and noise masks. So, given my previous
supposition of converting to p1/p0, and given that the maximum value in
FLOOR1_fromdB_LOOKUP is 1... then, which is the reference value used? I
first thought of the ATH (2e-05 Pascals), but, if so, the maximum value for
the floor would be the ATH...
