similar to: using matrix data for function

Hi All, I have a 8000*8000 matrix and I want to print out a file with the row name, column name and the value for those point with values satisfying a condition. I tried using a for loop, however, it took me forever to get the result. Is there a fast way to do this? Thanks!

Hi All, I am using the allShortestPath function based on Floyd's algorithm in e1071 package. It runs great when I have less than 5000 nodes. But when I tried to work on more than 5000 nodes, I ran into memory problem. The problem I really want to solve has 10000-15000 nodes. Does anybody know how to deal with this problem? Are there any other packages in R that can handle this problem?

Dear everyone, Your code is slow and you are interested in performance optimization for scientific software? Figuring out where’s the bottlenecks guided by performance evaluation tools. If you are interested in porting your code to a HPC hardware platform and architecture, than OpenACC as a user-driven directive-based performance-portable parallel programming model might be a solution. What are

Hi: I am using a machine with the 2.4.26 kernel, and trying to compare the performance of the HTB qdisc with the HFSC one. I have the following simple script that allows me to have a video stream on port 1234 while it limits a ttcp UDP stream so that the video stream is unimpaired. #!/bin/bash tc qdisc add dev eth0 root handle 1: htb default 12 tc class add dev eth0 parent 1: classid 1:1

One way to deal with this is to install R itself with mpicc. Then all packages are installed with mpicc and get the required MPI libraries and includes by default. I have done this with R-2.13.0 on an Opteron cluster running CentOS-5 a while ago and so far it has worked out great. I crosspost to r-sig-hpc and welcome others to comment if there are potential downsides to this solution. George

Greetings, I am a new user of R but a long time fan of S (Splus) and have installed R version 0.65.1 on a Windows NT machine. I would like to save plots as gif files and have been using savePlot() with some success. I found that savePlot would not work without modification, namely decrementing the device by 1 before calling the internal routine that does the conversion. Once that change was

In response to the Aug 20 posting by Vadim, I had the same issue with all kinds of complaints about row.names when it was not given in the read.table command; when it was set to NULL (data were actually shifted to the wrong names). I believe the problem was no comma (or specified delimiter) at the end of the first row with the names in it. Don't know why, but in comparing two programs,

It seems that someone was having trouble compiling R under Mac OS X 10.2, but I'm wondering if anyone is running the version available from http://www.apple.com/downloads/macosx/math_science/rformacintosh.html under OS X 10.2. This is important because I'm about to take delivery of a new Power Mac running 10.2! John Shonder Oak Ridge National Laboratory
