Sincerely, James Salsman P.S. I know I should be using data frames instead of parallel lists. This is just a simple example.

...oint model reliably comparable to the adjusted R^2 of a four-parameter, 100-point model? If such values can't be reliably compared with one another, then what is the reasoning behind adjusting R^2 for degrees of freedom? What are the good published authorities on this topic? Sincerely, James Salsman

...ints fall exactly on the simple linear regression line, and the predict() curve is nowhere near any of the data points. What am I doing wrong? What does the warning mean? Do I need more points?

How can ordinary polynomial coefficients be calculated from an orthogonal polynomial fit? I'm trying to do something like find a,b,c,d from lm(billions ~ a+b*decade+c*decade^2+d*decade^3) but that gives: "Error in eval(expr, envir, enclos) : Object "a" not found" > decade <- c(1950, 1960, 1970, 1980, 1990) > billions <- c(3.5, 5, 7.5, 13, 40) > #

I am having trouble converting a .flv file uploaded from Adobe Flex / Flash Player 10 to a Red5 server using the speex coder: http://livedocs.adobe.com/flex/3/langref/flash/media/Microphone.html http://jira.red5.org/confluence/display/codecs/Speex+Codec Questions: 1. How do I extract the audio track out of such a .flv file? 2. How do I convert it from Speex to .wav PCM? Thanks.

What happened to the category k-means package for performing k-means clustering on categorical variables? I expected it to become more prominent after the Netflix Challenge recommendation engine contest concluded, but instead it seems to have dropped from view. Where was it and where is it now, and why did it become less visible?

Dear Jean-Marc: Would you please send Thierry an ontology mapping table specification for speex according to the format he links to at the end of his message below? Thank you.

rtmplite -- http://code.google.com/p/rtmplite/ -- can be used to record Speex .flv audio and a/v files from Flash/Flex applets, and ffmpeg can be used to extract the Speex audio from such files, which can also be replayed on Flash. > Date: Tue, 23 Aug 2011 14:53:52 -0700 > From: Jozsef Vass <jovass at adobe.com> > > The only way to do this is to publish from Flash Player and
