I have Windows XP Professional Version 2002 and the R-Version 2.1.1. I did cluster analysis with the cluster package and the agnes (method = ?ward?). The results are satisfactory. But the dendrogram of agnes is confused to work with the results. Is there a tool, I can get a clear arrangement of the results for the cluster analysis. For example a matrix with different numbers for each group.

Dear friends Hello I'm a PhD student in Edinburgh University and interested in survival analysis. By chance, I found design library in Splus software. I have some questions about it and it's highly appreciated if you can help me. In its help (Design library help) I found the topics(not the commands), which are available in the main software. for instance, survival analysis is

Hi again, the previous answers were great. I was able to do what was planned. Now, I would like to do the following to a matrix: || year | event | team | total || where I can have multiple "event" per "team", but each "team" only has a "year" and a "total". Thus, this table has multiple lines for the same "team" where only the

Hello folks, The codebook infrastructure for Vorbis is now well underway. This is it! The last piece needed for *real* bitstreams. To that end, I have a decent VQ codebook generator running. I was originally using some farily typical merge/split algorithms and then decided that the right way to do this was to model a VQ codebook as an m-dimensional set of bubbles (like a foam). I know there

Hi, I am trying to implement ogg vorbis real time decoder on SHARC ADSP 21364 processor. I am writing my own version of the decoder using the documentation vorbis_I_spec.pdf from xiph.org. However I am facing certain hurdles in floor curve decoding during audio packet decode. In the spec it says that [cval] = read from packet using codebook number [so and so] in *scalar context*.(page no 43).

hello, does anybody know whether the codewords have a special meaning? whether they have a different influence like the quantization matriy in jpeg? e.g. do lower or the first entries have a greater influence than the last or higher codewords? thanks gerald

Hi all, <p>I have read the the source code about codebook generation, but there are some puzzles: Where can I get a latticebuild description file? How does one choose reasonable value0..value n on the second line of the latticebuild description file(.ql) to latticebuild? Does the output (xxx.vqi) of the resvqtrain have some relationships to the latticebuild description file ? Thank

Hi, All. I am a new one to vorbis codec, I want to write a vorbis decoder, so I read the vorbis specification, but when I read the paragraph about codebook stream format. I am totally confused, can any one give me some detailed information about the codebook. Thanks in advance He Yang

Dear R users, codebook (v. 0.5.8) was just released on CRAN. https://CRAN.R-project.org/package=codebook It uses the metadata/attributes that some other packages add (item labels, value labels, labelled missings) to automatically generate a codebook that is both human- and machine-readable. It combines metadata about the variables with data summaries. Many people will import this kind of

Hello, There is a coodebook for the pitch gains stored in pgain_table.h. How can we get such a table? I have read in the CELT's paper that the codebook is trained, but I do not understand what that realy means. Can anyone give me an idea about that? Thank you very much. -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi, can someone help me understand and experiment with Speex in a better way than my knowledge. I want to change the LPC filter order of the Speex algorithm. I think I need to change the LPC order( or lpcSize) in modes.c file. but to make it work I need to modify the codebook also, can someone tell me how to go about changing the codebook entries to support the changed order of prediction.

It's just an internal parameter that describes how the encoding is done at different bit-rate. In practice,

Bj?rn, I would be very interested in looking at your data and the R file. Actually, I think a lot of people would. You might want to post it on a website...

Do codebooks always start at byte boundaries, or can they start at arbitrary bit positions after the first codebook?

Is there a utility available that will dump the codebook information for a given Vorbis file. This would be useful to compare my own implementation against as a benchmark. Actually, a utility that would dump all of the Vorbis metadata would be quite useful as a development tool.

Is there a currently existing method in an R package for creating a codebook from a dataframe? Preferably, I would like to be able to export to a text file all relevant information. Thanks, Harold [[alternative HTML version deleted]]
