Hi, I have been using some of the functions in r for classification purposes, chiefly lda, qda, knn and nnet. My problem is that the only one I can figure out how to represenent graphically is lda (using plot.lda). I have tried 'fooling' this function into accepting qda input for plotting but to no avail. I wonder if you have any suggestions? Thanks alot, Anne Marie Power Marine lab.

Greetings, I would like to use some of the spatial statistics functions in R, but I am having trouble entering data. My data is already in a distance matrix format, not an X Y coordinate format (each Xij cell in the matrix represens the distance from point i to j). Does anyone know of a way to convert a distance matrix to a ppp object in spatstat, or an X,Y coordinate system for other packages? Thanks, Jesse [[alternative HTML version deleted]]

Derf's from-scratch alternate implementation of the theora codec is now publicly available from our subversion repository. http://svn.xiph.org/experimental/derf/theora-exp/ This exciting new codebase promises superiour performance, and the encoder is capable of higher quality output than the current represenation, taking advantage of the bitstream extension we've added to the

My server has 128 GB of RAM. However, R halted ever before it uses the memory. I have been able to load upto 250 CEL files but this time I wanted to test what would happen if I want to normalize 400 chips. Thanks

It looks like a reasonable first version, but it obviously needs to be extended for the final application. I would also recommend to install Polly and try to find the first test cases that cannot be handled. Some comments to your

I think this is a bug in the xl toolchain. lspci -s 0000:12:0.* 12:00.0 Display controller: ATI Technologies Inc Device 671d 12:00.1 Audio device: ATI Technologies Inc Device aa80 sudo xm pci-list-assignable-devices 0000:13:00.0 0000:13:00.1 0000:12:00.0 0000:12:00.1 So there is a multi-function device (actually one ASIC of a AMD Radeon 6990 card). It has two function addresses 0 = Display

Hi. My plan would be: 1w Study sources of Polly and LLVM docs relating to analysis. 2w Create tests which demonstrate problems with NSW/NUW 3-4w Fix the handling of wrap overflows. 5w Complete middle term paperwork. 6w Create tests for each of cases which are not currently optimized (e.g. have min/max, sext/zext, trunc or unsigned comparisons in the loop bounds or memory accesses). 7w Learn how

Hi I've tried to get doxygen documentation by configuring with --enable-doxygen. Then 'make install' has been interrupted with message "error: configuration file /media/data/virtual/share/gsoc/build/docs/doxygen.cfg not found!". mikem, why did you remove a line "AC_CONFIG_FILES([docs/doxygen.cfg])" in autoconf/configure.ac [1] ? I've restored this line. Now

Hi, We are in the business of developing/productizing Multimedia codecs for embedded systems. Recently, Vorbis has gained good popularity. We are also developing it. But we face few problems related to patents. Vorbis claims to be patent free. Is there any particular search made for possible patent infringements and corresponding report published? We need to convince our customers sometime

Hi, I ran into a problem wherein my mail client (RoundCube) would not display a message from a Dovecot IMAP server (claiming that the message had no content). The raw source of the message looked fine, but the body structure returned by Dovecot only had the first text/plain part and not the alternative text/html part. The message looks like: ... headers removed ... X-Mailer: Lotus

Hello, Suppose I have x, which is a variable of class numeric. The calculations performed to yield x imply that mathematically it should be an integer , but due to round-off errors, it might not be (and so in either direction). The error is however small, so round(x) will yield the appropriate integer value. Moreover, this integer values is guaranteed to be representable by an

Hi. I see that to detect scops firstly we search for regions in CFG ( by RegionInfo ) and then select regions that answer some requirements ( in ScopDetection ). Because only affine expressions in conditions and bounds are permissible, we trying to get scalar expressions into affine form by AffineSCEVIterator. At present there plugs for scev types Truncate, ZeroExtend, SignExtend, UDivExpr,

Dear all R users, I am really struggling to determine the most appropriate lag order of ARIMA model. My understanding is that, as for MA [q] model the auto correlation coeff vanishes after q lag, it says the MA order of a ARIMA model, and for a AR[p] model partial autocorrelation vanishes after p lags it helps to determine the AR lag. And most appropriate model choosed by this argument gives
