I'd like to convert a dist into a table/matrix/thingy of the form: A B value A C value B C value (assuming the dist was over 3 names). Is there a way to do this without using a for loop? -- Taral <taralx at gmail.com> "Please let me know if there's any further trouble I can give you." ? ? -- Unknown

One piece of code I'm writing has a lot of intermediates, and I'm trying to optimize down the number of memory accesses. Here's a snippet from the start of the function, where I think there is some low-hanging fruit: # BB#0: pushq %rbp pushq %r15 pushq %r14 pushq %r13 pushq %r12 pushq %rbx movq %rdx, %rcx movq %rdi, -16(%rsp) # 8-byte Spill movq (%rsi), %rdi movq

Here's the code and compilation steps: #include <stdint.h> typedef unsigned int uint128_t __attribute__((mode(TI))); typedef struct{ uint64_t l[5]; } s; void f(s * restrict r, const s * restrict x, const s * restrict y) { uint128_t t[5] = {0, 0, 0, 0, 0}; #define BODY(i,j) { int i_ = i < j ? i : j; int j_ = i < j ? j : i; uint128_t m = (uint128_t) x->l[i_] *

Dear all, It seems to be a recurrent problem to me and I am asking your help to get over it once for all ... My idea is : I have variables C_1, C_2, C_3 ... that corresponds to vectors of size n, and I would like to cbind them. I get a vector of their names using : temp<- ls(pat="C") And I like to find a way to use this vector temp as an argument to cbind.

Hi Rusers, I hope to divide the original dataset into several subsets and output these multilple datasets. But errors appeared in my loops. See example. ###### a<-c(1:10) b<-c(rep(1,3),rep(2,3),rep(3,4)) c<-data.frame(a,b) #c is the example data num<-c(unique(b)) # I hope to get the subsets c_1.csv,c_2.csv and c_3.csv #Errors for (i in num) { c_num<-c[c$b==num,]

Hi everyone, I want to plot some pattern. For example, I have some coding as below, plot(0:11,type="n") polygon(c(6,8,10), c(7,3,5),bor=6) polygon(c(2,4,6), c(5,3,7),bor=6) polygon(c(6,10,8), c(7,9,11),bor=6) polygon(c(2,6,4), c(9,7,11),bor=6) This coding will give me four triangles, but how to generate more triangles in sequences so that not need to mention the coordinate for each

Hi, I have a piece of code originally written for s-plus - I am trying to run it in R now. The code was obtained from someone who is now not available to give any pointers and I am a beginner in R. Here is where it is getting stuck: > +names(good.motifs[,1]) Error in +names(good.motifs[, 1]) : Invalid argument to unary operator here is now names(good.motifs,1]) looks: >

Hello, I've been debugging a few different tessellation shader issues with nouveau, but let's start small. I see this issue on my GK208 with high frequency, and I *think* I've seen it once or twice on my GF108, but it's exceedingly rare, if it does happen. I don't have a GK10x to test on, unfortunately, but I assume it'll have the same issue as the GK208. The issue is

Hello everyone, What do you think about having localized the following CentOS components: - Rolling notes in CentOS installer. These images are shown during the installation process, once the configuration is done and you are waiting for packages to be installed. Rolling notes are a great place to promote CentOS. If they are not localized, they are shown in English language by default.

Hi, I am very new to R and wanted to know if there is a package that, given very long nucleotide sequences, searches and identifies short (7-10nt) motifs.. I would like to look for enrichment of certain motifs in genomic sequences. I tried using MEME (not an R package, I know), but the online version only allows sequences up to MAX 60000 nucleotides, and that's too short for my needs..

One additional observation that I just made is that on GK208, the blob apparently doesn't use the result of S2R Rx, SR_INVOCATION_ID wholesale in TCS. It either passes it through a I2I.S32.S32 Rx, |Rx| (i.e. absolute value), or even more paradoxically, shl 2; shr 2; which removes the top *2* bits, rather than just the top 1. However I see no such behaviour on GF108. I'm going to test out

Please change all longs to int, and never use them in the future :) They arent needed as on most platforms they are the same size. (which is the assumption made in the ogg code anyway) The reason for this is i will have vorbis support on playstation 2, but long is 64 bits, and they are excruciatingly slow. cheers Brett Paterson --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg

I saw some mail go by a bit ago about doubles-vs-floats, but I seem to have lost it. I'm interested in rewriting the mdct code using Altivec on MacOS X. Altivec doesn't support doubles, though -- the only floating point vector type is single precision floats. Vorbis currently has doubles everywhere -- is this really necessary? Doubles are supposedly faster than floats in the PPC

Hi, I don't really know the details of the discussion, but I'd like to present this issue from a user-oriented perspective, and from the perspective of how Nautilus wants to use data files. In brief, Nautilus makes the assumption that the mime type is sufficient to pick the right applicatiob or pluggable component to view/edit a particular content type. This is quickly coming to be the

Dear R users, I can get a filled triangle pointing upwards by specifying pch=17 in xyplot or lpoints, but how do I get a filled triangle that points downwards? In the standard plot function it's possible to use plot(x,y,pch=25,bg="black"), but bg= doesn't seem to work with lattice and lpoints. Thanks, Hans Gardfjell Ecology and Environmental Science Ume?

Dear R-helpers, an rgl-ers in particular, what is the easiest way to plot a section of a plane in 3D, that is given by the xyz coordinates of the outline? Suppose I have a polygon - which I know for sure is a set of coordinates on the same plane. One method I found is to use surf.tri from the geometry package, and then plot the triangles with rgl.triangles. This method is not perfect though,

Hi Inaki, > "Performant"... in terms of what. If the cost of copying the data > predominates over the computation time, maybe you didn't need > parallelization in the first place. Performant in terms of speed. There's no copying in that example using `mclapply` and so it is significantly faster than other alternatives. It is a very simple and contrived example, but
