intro + specification remarks + some questions
hi everyone, since about 10 days I've been working on an implementation of ogg vorbis *decoder* from scratch, and I've got a few constructive remarks about the specs and some questions. -------------------------- First a question: > 9.2.4. low_neighbor > > "low_neighbor(v,x)" finds the position n in vector [v] of the greatest > value scalar element for which

Huge VQ codebooks
Hi, Does anybody know how codebooks are generated in OggVorbis encoder? We are porting oggorbis encoder on embedded platform for which VQ codebook memory is hugeeee to imagine. How can we reduce that? Can we do VQ with less codebooks and if yes how? If any help available? Parul Embedded Engineer Einfochips Ltd

VQ and Huffman codebooks creation
Hello, I'd like to know in detail how does the creation of VQ and Huffman codebooks work in Vorbis. I've used the source code from *encoder_example* as guide, but the only reference I've found is the function *_make_words *inside * vorbis_book_init_encode*, which creates the Huffman tree if I'm not wrong. So I have two doubts. The first is that, for creating the Huffman tree (and

Subtracting number of days from a date
Hi group, suppose I have a date, say May 15 2004, and I want to now what date it is 23 days before that date. The way to calculate the new date should (...) take account of leap years :) In pseudocode: olddate <- "May 15 2004" newdate <- olddate-23 I looked around in POSIXct etc..., maybe I overlooked?

Looping through a list of objects & do something...
Hey Folks, Could somebody show me how to loop through a list of dataframes? I want to be able to generically access their elements and do something with them. For instance, instead of this: df1<- data.frame(x=(1:5),y=(1:5)); df2<- data.frame(x=(1:5),y=(1:5)); df3<- data.frame(x=(1:5),y=(1:5)); plot(df1$x,df1$y); plot(df2$x,df2$y); plot(df3$x,df3$y); I would like to do something like:

Another simple q - removing negative values
Sorry folks but again I have failed in my understanding of how to do a very simple thing. I've read the various texts and searched the help archives but no positive result so far. I want to remove all the rows in a data frame where one of the variables has negative values. In approx Stata pseudocode: drop _all, if( x < 0 ) Please either point me to relevant sections of the docs or

how experimental are the llvm.experimental.vector.reduce.* functions?
I'm interested in using @llvm.experimental.vector.reduce.smax/umax to implement runtime overflow checking for vectors. Here's an example checked addition, without vectors, and then I'll follow the example with what I would do for checked addition with vectors. Frontend code (zig): export fn entry() void { var a: i32 = 1; var b: i32 = 2; var x = a + b; } LLVM IR code:

C code generators
Dear R-helpers Are there any established R packages that include a C code generator -- that generates new C language files and compiles them? To be precise what I'm looking for is a process that takes text input in some format (it might be pseudocode, fragments of C code, etc) and creates a valid C language source file that can be compiled by R CMD COMPILE. Ideally the procedure should also

Looking for the name of a certain kind of quantile plot
Hi, While playing with quantile-quantile plots, I wrote up some code which plots something strangely different. Here's the pseudocode: testhist <- hist(sample_data) refhist <- hist(rnorm(n, mean=0,sd=1)) # for some large-ish n cumtest <- cumsum(testhist) cumref <- cumsum(refhist) plot(cumref,cumtest) This produces a straight line of slope 1 for a sample with the same

VQ codebook sanity check (please help)
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

Register Allocation Graph Coloring algorithm and Others
Hi GCC and LLVM developers, I am learning Register Allocation algorithms and I am clear that: * Unlimited VirtReg (pseudo) -> limited or fixed or alias[1] PhysReg (hard) * Memory (20 - 100 cycles) is expensive than Register (1 cycle), but it has to spill code when PhysReg is unavailable * Folding spill code into instructions, handling register coallescing, splitting live ranges, doing

how experimental are the llvm.experimental.vector.reduce.* functions?
The IR update to allow vector types was here: https://reviews.llvm.org/D57090 ...we didn't update the docs at that time because it was not clear what the backend would do with that, but that might've changed with some of the more recent patches.

How to avoid for or while loops when one index depends on another
Dear R Community, I'm trying to exploit the elegance of R by doing the following pseudocode routine without a WHILE or FOR loop in R: for i = 1 to length-1 for j = (i+1) to length print a[i], a[j] That is, I want i and j to be the indices of a half-matrix 1 2, 1 3, 1 4, ..., 1 length, 2 3, 2 4, ..., 2 length, 3 4, ..., 3 length 1. Can this be done with the 'whole

Slow computation in for loop
Dear members, I'm using R to do some test computation on a set of parameters of a function. This function is included in three for() loops, first one for replications, and the remaining two cycling through possible parameters values, like this : for (k in replicates) { data <- sampling from a population for (i in param1) { for (j in param2) { result <- function(i,
