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.

two questions about PLOT

funnel shift, select, and poison
...e to add that the general question here is "where does > poison stop propagating" and this question needs to be definitively > answered by this community. 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. -Krzysztof

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. [[alternative HTML version deleted]]

"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? Colin [[alternative HTML version deleted]]

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). >mydata Plot Model Individuals Time Observed Predicted 1...

mutlivariate normal and t distributions
...write it was the need to have functions which compute the distribution functions in a non-Monte Carlo form, sinse this caused me problems when these probabilities are involved in a minimization problem. For this reason, I could not make use of the CRAN package 'mvtnorm'. Exactly to avoid superposition with the CRAN package, 'mnormt' is made available somehere else, in case other people want to use it. The package 'mnormt' is at http://azzalini.stat.unipd.it/SN/Pkg-mnormt As explained, this is not uploaded to CRAN just to avoid clash with the existing package. However, if it...

Best Practices for Data Recovery for corrupted EXT2/3?
...ain drive AND the backup drive). I immediately DD'd the main drive over to an 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...

Duncan - 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. https://sentientsyllabus.substack.com/p/chatgpts-achilles-heel Now, the curious question is: why can it program. Why is its production of R-syntax less vulnerable to this effect than a literature quote, or reference? M...

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...

The output of Predict is suitable for direct use by lattice (e.g., the xyplot function) and ggplot2 if you don't want to use plot.Predict. plot.Predict allows you to specify a lattice formula (less the left hand side) if you don't like plot.Predict's choice of superpositioning and panel variables. The following outlines the most significant change users will need to make (the web page contains the complete list). Note that the convention used for getting predictions over the default range is now predictor=. rather than predictor=NA. require(rms) # instead of De...

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 lattice in

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...

stationary "terminology" time series question
This is not exactly an R question but the R code below may make my question more understandable. If one plots sin(x) where x runs from -pi to pi , then the curve hovers around zero obviously. so , in a"stationary in the mean" sense, the series is stationary. But, clearly if one plots the acf, the autocorrelations at lower lags are quite high and, in the "box jenkins"

An interesting chat with ChatGPT
I was wondering which anchor would match in the regular expression "(a)|(b)" if both "a" and "b" matches the target string. What appears to happen is that the first match wins, and that's how it is documented in Python, but I was looking for docs on this in R. As far as I can see, the ?regex help page doesn't resolve this. So just for fun, I decided to
