search for: triplets

I have a list (length 750), each element containing a vector of unique strings (unique gene ids), with length up to ~40 (median 15). I want to compile a matrix of all possible triplets and their frequency within gene elements. Using combn and a lot of looping, I am accomplishing this but it is VERY slow. I've tried to figure out a way to vectorize this, using "match" and "%in%", but can't get my mind around it. Below is my code. sig.tf.pairs is th...

I noticed that the base64 functions in util.c don't produce the same results as other versions that implement RFC 1421 (and its successors). This results in PEM files that can only be decoded by tinc itself. Is this intentional? Below is a diff to make tinc's base64 functions match what everyone else does. This will break existing key files, though, which is unfortunate. - todd diff

I'm attempting to create a sequence for an experiment and am hoping I can use R to create it. It has several constraints: (1) It is made up of two sequences (red and green) that have 4 different repeating triplets (e.g. T1=ABC T2=DEF T3=GHI JKL) (2) Each sequence has the following constraints: (a) there cannot be repeating triplets (e.g. T1 T1), (b) there cannot be repeating triplet pairs (e.g. T1 T2 T1 T2) (3) Triplets occur with the following frequency: T1=20, T2=23, T3=26, T4=36 (same for red and green se...

First, happy holidays, everyone! Thanks to the R team for bringing out 1.4 before the new year. I have 10000 integer triplets stored in A[1:10000, 1:3]. I would like to find the unique triplets among the 10000 ones with possible duplications. What is the easiest way for this. I know the function unique(), which apply to a vector, not the 10000*3 array in my problem. Thanks in advance. Jason ===== Jason G. Liao, Ph.D....

I think that this is an easy one... I have a matrix where each row is an (x,y,z) triplet. Given a potential (xnew,ynew,znew) triplet I want to know if the matrix already contains a row with the new values (the space already has that point). I can do it using a for loop, but I would like to know if there is anyway in which I can do it without the for loop. I do it now like this (this

Hi all, I met this error(title) when i was trying to compile llvm-gcc-4.2-2.7 on loongson2f,a mips compatible platform.I also failed to build a cross-compiler and the error message was the same . Is that means llvm-gcc cannot support mips back-end now? Thanks. Here is my configure options: $export TARGET=mips64el-unknown-linux-gnu $../../src/llvm-gcc-4.2-2.7.source/configure

Hello, does anybody know how to achieve the following with SSH... a) accept RSA authentication for all but root from any IP b) accept RSA authentication for root from a couple IPs/Netmasks c) accept password authentication for all but root from a dozen Netmasks d) accept password authentication for root from 3 local netmasks only ie. make authentication depend on the

...9; package, I have not been able to figure out how the plot() method converts colorspace coordinates to RGB values for display on the screen. I am convert between colorspaces with the various as() methods... but cannot seem to find a way to extract RGB (i.e. for displaying on a computer screen) triplets from color space coordinates. Here is a sample of the data that I am working with: H V C x y Y 2.5Y 0.2 2 1.43 0.97 0.237 2.5Y 0.4 2 0.729 0.588 0.467 2.5Y 0.6 2 0.563 0.491 0.699 2.5Y 0.6...

Estimados Les consulto por redes neuronales, hay diversos artículos como los siguientes (el último tienen un error actualmente). Pero mi pregunta va un poco por otro lado. http://www.r-bloggers.com/build-your-own-neural-network-classifier-in-r/ http://www.r-bloggers.com/classification-using-neural-net-in-r/ Básicamente se puede calcular un valor, por ejemplo doblar 2,4 grados a la derecha, luego 1

In the Matrix package v. 0.995-11 I see that the dgTMatrix Class for compressed, sparse, triplet-form matrices handles Identically indexed data instances by summing their values, e.g., library(Matrix) (Mt <- new("dgTMatrix", i = as.integer(c(0,0,1,1,4)), j = as.integer(c(0,1,2,2,4)), x = as.double(1:5), Dim = as.integer(c(5,5)))) ## 5 x 5 sparse Matrix of class

Hey all, I'm currently working through the problems at Project Euler -- this question came up while working on Problem 9 (http://projecteuler.net/problem=9): "A Pythagorean triplet is a set of three natural numbers, a < b < c, for which, a^2 + b^2 = c^2. For example, 3^2 + 4^2 = 9 + 16 = 25 = 5^2. There exists exactly one Pythagorean triplet for which a + b + c = 1000. Find the

Hello A suggestion to LLVM (assembly) language designers. It could be worthwhile to extend the LLVM language http://llvm.org/docs/LangRef.html#i_call so that calls may return more than one result (for example, Common lisp functions can return more than one result). The intent could be to extend the ABI calling conventions to permit a function to return a few results (all in registers), instead

Hi, List, In checking the page fault problem when using pv-grub to start domU in opensuse12.3[1], found that the problem is caused by ''-fstack-protector'' flag which is introduced in rpm build: export EXTRA_CFLAGS_XEN_TOOLS="$RPM_OPT_FLAGS" export EXTRA_CFLAGS_QEMU_TRADITIONAL="$RPM_OPT_FLAGS" export EXTRA_CFLAGS_QEMU_XEN="$RPM_OPT_FLAGS" with
