I have a bunch of lines I want to plot using plotCI() What Id like to know is, how can I connect the points with a line and how can I print multiple lines on the same graph? -- View this message in context: http://www.nabble.com/plotCI----multiple-plots-on-same-graph-tp19435198p19435198.html Sent from the R help mailing list archive at Nabble.com.

I have a file of the following form -11 -10 -9 -8 -10 -9 -8 NA -9 -7 NA NA -8 NA NA NA So basically a NxN matrix of log scores. I want to get a heatmap of these log scores but I'm having a problem. I'm using the following code library(gplots) data=read.table("filein.txt",header=FALSE) mat=as.matrix(data) heatmap.2(mat,dendrogram=c("none")) But on the

I want to make sure this piece of code I wrote is doing what I want it to do. ll<-function(string) { grep(string,dir(),value=T) } subdir = ll("Coverage_[1-9][0-9]$") I basically wrote a little function that would grab all the files of form Coverage_[0-99] The way I wrote it, will it grab Coverage_5 or does it have to have 2 numbers (10-99)? -- View this message in context:

I'm trying to display the probability space of a function and wanted to see specifically where the maximum posterior probability is. data=read.table("PosteriorData",header=F) mat=as.matrix(data) heatmap.2(mat/max(mat,na.rm=T),dendrogram=c("none"),trace=c("none"), Rowv=F,Colv=F,labRow=3*c(10:-10),labCol=3*c(-10:10),symm=T,col=rainbow(100)) As the

Sorry, it seems I have only replied to Lakhdar, not to the newsgroup. Below is my reply to Lakhdar, and I would like to make it more clear now, using some pseudo values for simplicity: I read bytes 1 to 124 from my encoded spx file. I decode themt and get the values: ---Frame 1---- -293 -8234 2134 17 ---Frame 2---- -9323 -732 189 2329 Both frames are just perfect as I need them. But now when I

Dear R users, I am analysing a very large data set and I need to perform several data manipulations. The dataset is so big that the only way I can play with it without having memory problems (E.g. "cannot allocate vectors of size...") is to write a batch script to: 1. cut the data into pieces 2. save the pieces in seperate .RData files 3. Remove everything from the environment 4. load

Dear all, According to CHANGES IN R 3.0.0: o diag() as used to generate a diagonal matrix has been re-written in C for speed and less memory usage. It now forces the result to be numeric in the case diag(x) since it is said to have 'zero off-diagonal entries'. diag(x) does not work for character vector in R 3.0.0 any more. For example, v <- c("a",

Hi, Here is a preliminary (monolithic) version you can comment on. This is still buggy, however, and I'll be testing for and fixing bugs over the next few days. I've used your version of the strong siv test. Thanks! -- Sanjoy Das. http://playingwithpointers.com -------------- next part -------------- A non-text attachment was scrubbed...

Hello, I m unable to vectorize following kernel by opt tool; for (i = 0; i < _PB_NI; i++) for (j = 0; j < _PB_NJ; j++) { tmp[i][j] = 0; for (k = 0; k < _PB_NK; ++k) tmp[i][j] += alpha * A[i][k] * B[k][j]; } for (i = 0; i < _PB_NI; i++) for (j = 0; j < _PB_NL; j++) { D[i][j] *= beta; for (k = 0; k < _PB_NJ; ++k) D[i][j] +=

Hi, I am looking for C/C++ codes for computing generalized inverse of a matrix. Can anyone help me in this regard? Thanks, Mahbub.

It would help if you sent the IR you're giving to opt or at least a complete C function and your clang command line. ~Craig On Wed, Mar 14, 2018 at 3:05 PM, hameeza ahmed <hahmed2305 at gmail.com> wrote: > Hello, > > I m unable to vectorize following kernel by opt tool; > > for (i = 0; i < _PB_NI; i++) > for (j = 0; j < _PB_NJ; j++) > { >

Hello, I am trying to create a new vector (w) that is based on comparing two vectors (P and Z). The compaison is simple (I created a for loop that reassigns w based on if statement), all Z values >= 24 and P values <=1, w=88 else w=77. I am not getting the correct results for w, see example code below. Any thoughts or suggestions on the correct method. Thank you, Doug P <-

I am able to vectorize it with the following code; #include <stdio.h> #define N 100351 // This function computes 2D-5 point Jacobi stencil void stencil(int a[][N], int b[][N]) { int i, j, k; for (k = 0; k < N; k++) { for (i = 1; i <= N-2; i++) for (j = 1; j <= N-2; j++) b[i][j] = 0.25 * (a[i][j] + a[i-1][j] + a[i+1][j] + a[i][j-1] + a[i][j+1]); for

Does it happen due to loop carried dependence? if yes what is the solution to vectorize such codes? please reply. i m waiting.

Hello. Could you please tell me why the first loop of the following program (also maybe the commented loop) doesn't get vectorized with LoopVectorize (from a recent LLVM build from the SVN repository from Jun 2018)? typedef short TYPE; TYPE data[1400][1200]; void kernel_covariance(int m, int n, TYPE mean[1200]) { int i, j, k; for (j = 0; j < m; j++) { mean[j] =

Hi Tobias, could we use information about memory accesses of a SCoP statement and def-use chains to determine statements, which don’t contain matrix multiplication of the following form? for (int i = 0; i < Upper Bound1; i++) for (int j = 0; j < Upper Bound2; j++) for (int k = 0; k < Upper Bound3; j++) C[i][j] += A[i][k] * B[k][j] We could probably check that memory access

Hi all, I've searched high and low on this and found nothing of help.

I want pa9 to be my vector that counts how many of these are classed as in poverty. My problem is that my command if(a9[i] <

Hi, there I am writing an backend, and I met a problem. We don't have load/store instructions for vector predicate registers(vpr for short). The hardware has 64 vector registers(vr for short) and 8 vector predicate registers. And there is no move instructions between vr and vpr. vr supports many operations, and vpr supports vpror, vprxor, vprand and vprinv operations. A vr has 512 bits, and
