similar to: Extract indices after comparing two vectors

Dear All, I would like to know how to sort a vector of numeric values such that we know the original index of each ordered component. Say, we have c <- c(1,4,3,2) csort <- sort(c,descreasing=FALSE) With a few components of c, we can manually find out: csort[1] = 1 = c[1], ie, the original index of csort[1] is 1, csort[2] =2 =c[4], ie, the original index of csort[2] is 4. When length(c) is

Hi, Following is excerpted from dynamic-vector-gep.ll. The resulting "extractelement" seems to always return 0.0f regardless the value idx1 and idx2 is holding. Am I missing something here or there is something fishy take place? Thanks Shuxin 101 ; CHECK: test6 102 ; CHECK: insertelement <4 x float> zeroinitializer, float 1.000000e+00, i32 %idx1 103 ; CHECK:

Hi Shuxin I think i might have written that test. And yeah, no matter what values you get you’ll get a 0.0. Its probably a bad test case, but i can’t remember if it exposed a bug in this form or not. Since writing it Chandler rewrote SROA anyway so the original bug is long gone. Thanks, Pete On Apr 5, 2013, at 11:57 AM, Shuxin Yang <shuxin.llvm at gmail.com> wrote: > Hi, > >

For the gep: %idx1 = getelementptr i32* %MyVar, i32 0 i32* is the type that MyVar is pointing to and i32 is the type of the offset value, or what? If it's the type of offset value, then the size of the pointer shouldn't be less than i32, correct? The index is 0, so in this example, the address computation is idx1 = &MyVar+0. What I want to know is the size in bits of the values

Dear All, I would like to define a function: f(x,y,z) with three arguments x,y,z, such that: given values for x,y, f(x,y,z) is still a function of z and that I am still allowed to find the root in terms of z when x,y are given. For example: f(x,y,z) = x+y + (x^2-z), given x=1,y=3, f(1,3,z)= 1+3+1-z is a function of z, and then I can use R to find the root z=5. Thank you. -Chee [[alternative

There are two C++ signatures for CreateConstGEP1_32: Value * CreateConstGEP1_32 (Value *Ptr, unsigned Idx0, const Twine &Name="") Value * CreateConstGEP1_32 (Type *Ty, Value *Ptr, unsigned Idx0, const Twine &Name="") I'm assuming that this means that the caller can supply the expected type, and get error checking or casting? Or choose to not supply the

Hi, After reading some of the posting in this list, I came across this posting from: From: Peter Dalgaard <p.dalgaard_at_biostat.ku.dk> Date: Fri 29 Oct 2004 - 08:02:40 EST Replying to Re: [R] Errors during make check He described a problem similar to mine, that build 64-bit R (I am building R version 2.0.1) with sunperf library gives a core dump during make check. So I configured my

Dear All, I would like to ask a question on how to find the index of the minimum of entries of a numeric vector, without using loops or user defined functions. Suppose we have a vector: a <- c(3,1,2) then, min(a) = 1 and its index is 2. Target: how to get the index of this minimum? How to get the indices if multiple entries assume this same minimum? Thank you, Chee [[alternative HTML

Just installed samba-3.0.0beta1 and trying to use swat. When clicked on help on a particular paramenter (any one), a new window pops up and supposingly it will load smb.conf.5.html and then jumps to the label of the parameter. But now it doesn't work. smb.conf.5.html is no longer complete. Checked under docs/docbook/smbdotconf and found that smb.conf.5.xml supposingly should include files

Dear All, I would like to generate m positive real numbers c_i, I=1,...,m, such that (1) c_1 + c_2 + ... + c_m=m, (1) after being ordered into c_1 >= c_2 >= .... >=c_m>0, we have that c_m is of the same order of m^(-1/8), when m is sufficiently large.

Dear All, For function: rmvnorm{mvtnorm} in (library mvtnorm, not splus2R), if I generate 2 bivariate normal samples as follows: > rmvnorm(2,mean=rep(0,2),sigma=diag(2)) [,1] [,2] [1,] 2.0749459 1.4932752 [2,] -0.9886333 0.3832266 Where is the first sample, it is stored in the first row or the first column? Does this function store samples row-wise or column-wise? Thank

Dear All, I would like to know, beside writing a function and then apply it to a list, or using a for loop, whether there is a one-line command to do the following. Suppose we have a list, each of whose components are numeric: > a <- vector("list",3) > a[[1]] <-c(1,2) > a[[2]] <-c(3,4) > a[[3]] <- c(5,6) > a [[1]] [1] 1 2 [[2]] [1] 3 4 [[3]] [1] 5 6 Target:

Dear All, As always, I appreciate all your help. I would like to know the easiest way to convert each of the homogeneous elements of a numeric list into a matrix. Each element of this list is also a list such that when displayed, looks like a 2-by-3 matrix , I would like to convert each of them into a matrix, without changing the double index of each entry. Suppose: a<-

Dear All, I would like to ask a question on how to do overlay plots in each subgraph of xyplot. 1. I did simulations for m=1000, 2500, 5000, 10000, as the sample sizes. 2. for each sample size value m, 4 graphs are generated; each graph contains overlayed comparisons between 4 methods, 3. now I want put them into a 4-by-4 plot by xyplot, i.e., 4 sample size values, each of which has 4 plots.

I am looking for a way to do multiresponse parameter estimation for a problem that is quite similar in form to the alpha-pinene example in Bates and Watts (1988), p. 147, where the model is a set of ODEs. I am specifically interested in obtaining the parameter covariance matrix, as well. Which package(s) in R would I use to do such a thing? Mark Schaffer Dept. of Chemical Engineering

Dear All, In Storey's estimator of the proportion of true nulls, the estimator depends on the tuning parameter lamda. Suppose now that an estimator of this proportion has been obtained by the qvalue package, what is the lamda that corresponds to the estimate? How to get this lamda?

Dear All, Suppose Z_i, i=1,...,m are marginally identically distributed as a two normal mixture p0*N(0,1) + (1-p0) *N( miu_i, 1) where miu_i are identically distributed according to a mixture and I have generated Z_i one by one . Now suppose these m random variables are jointly m-dimensional normal with correlation matrix M= (m_ij). How to proceed next or how to start correctly ? Question:
