Hi How do I generate all ways of ordering sets of indistinguishable items? suppose I have two A's, two B's and a C. Then I want AABBC AABCB AACBC ABABC . . .snip... BBAAC . . .snip... CBBAA [there are 5!/(2!*2!) = 30 arrangements. Note AABBC != BBAAC] How do I do this? -- Robin Hankin Uncertainty Analyst National Oceanography Centre, Southampton European Way, Southampton SO14

Hi I want to enumerate all vectors of length "J", whose elements are integers in the range 1 to S, without regard to ordering. With J=S=3, the combinations are as follows: [,1] [,2] [,3] [1,] 1 1 1 [2,] 1 1 2 [3,] 1 1 3 [4,] 1 2 2 [5,] 1 2 3 [6,] 1 3 3 [7,] 2 2 2 [8,] 2 2 3 [9,] 2

I have a problem where I need to loop over the total combinations of vectors (combined once chosen via combinatorics). Here is a simplification of the problem: STEP 1: Define three vectors a, b, c. STEP 2: Combine all possible pairwise vectors (i.e., 3 choose 2 = 3 possible pairs of vectors: ab,ac, bc) NOTE: the actual problem has 8 choose 4, 8 choose 5 and 8 choose 6 combinations. STEP

As we all know, in R indices for vectors start with 1, i.e, x[0] is not a correct expression. Some algorithms, e.g. in graph theory or combinatorics, are much easier to formulate and code if 0 is an allowed index pointing to the first element of the vector. Some programming languages, for instance Julia (where the index for normal vectors also starts with 1), provide libraries/packages that allow

Dear all, Is there any method in R to find all possible nonnegative integer solutions to the linear equation with unit coefficients as follow: X1+X2+...+Xk=N Thank you, Amin Zollanvari

I have a whole slew of questions about optimization passes. Answers to any or all would be extremely helpful: How important are doInitialization/doFinalization? I can't detect any difference if I use them or not. Why does the function pass manager have doInitialization/doFinalization, but the global pass manager doesn't? If I am applying the function passes to many functions, do I

Dear useRs, French reading people among you might be interested by the following book: Noel, Y. (2013). Psychologie statistique avec R [Statistical psychology with R, in French], coll. PratiqueR, Paris: Springer. http://www.springer.com/psychology/book/978-2-8178-0424-8 This book provides a detailed presentation of all basics of statistical inference for psychologists, both in a fisherian

Hi I have a little vector function that takes a vector A of strictly positive integers and outputs a matrix M each of whose columns is the vector, modified in a complicated combinatorical way. Now I want to generalize the function so that A can include zeroes. Given A, I want to strip out the zeroes, pass it to my function, and pad M with rows at positions corresponding to the zeroes

I had a similar issue with arm vs thumb in mach-o. Each function’s thumbness is marked in its symbol table entry. But it is even worse, a function could change encoding in the middle (only hand coded assembly could do this). My solution was to add a new Reference Kind for mach-o which is the current instruction encoding. The offsetInAtom() is the offset where the encoding kind changes.

I guess we'll have to add that to the list of things that needs to be done to replace the old JIT. In the projects I've worked on that use MCJIT, we've been using getPointerToFunction and then calling it from outside the MCJIT engine, but I suppose that the generic handling in runFunction would be useful in some cases. -Andy -----Original Message----- From: llvmdev-bounces at

Hello group, I am learning R and I am new to many concepts.I face the following errors when I am trying to execute the following. I have 4 text files with protein accession numbers. I wanted to represent them in a venn diagram and for that I using intersect and setdiff functions. My data looks like this: file1.txt (c): NP_000005 NP_000020 NP_000030 NP_000053 file2.txt(e): NP_000005 NP_000020

Hi all, I have some rough code to sample consecutive integers with length according to a vector of lengths #sample space (representing positions) pos<-c(1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20) #sample lengths lengths<-c(2,3,2) From these two vectors I need a vector of sampled positions. the sampling is without replacement, making things tough as the sampled integers need

Dear R-helpers, I am a beginner using R. This is the first question in this list. My question, Is there possible to make combinations with two part column? If I have a number 1,2,3,4,5,6,7,8. I need the result something like below: 1,2,3,4,5 6,7,8 1,2,3,4,7 5,6,8 2,3,4,5,6 1,7,8 1,2,3,6,7 4,5,8 1,2,3,4,8 5,6,7 3,4,6,7,8 1,2,5 .... I would be very happy if anyone could

STO_MIPS16 and STO_MICROMIPS flags denote that the symbol use a different "compressed" instructions encoding. Both these flags can be combined with usual "visibility" flags. It looks like adding new flag into the contentTypes set might solve the problem. Thanks for the idea. I try to implement it. On Thu, Nov 6, 2014 at 6:52 PM, Shankar Easwaran <shankare at

I'm trying to plot Venn diagrams with more than 3 sets (5 actually) in order to describe graphically the genetic variation between populations. I tried the limma library but realised it can only plot 3 sets. Is there any solution? Of course I could plot the chart manually but it'll take too long (have other datasets)..... One of my dataset is given below. THanks for any advice. j
