The small bit of script below is an example of what I'm attempting to do - find the day on which the 'center of mass' occurs. In case that is the wrong term, I'd like to know the day that essentially cuts the area under the curve in to two equal parts: set.seed(4004) Date <- seq(as.Date('2000-09-01'), as.Date('2000-09-30'), by='day') hyd <-

Eric B's response provided just the kind of quick & simple solution I was hoping for (appears as the function com below). However, I once again failed to take advantage of the power of R and have reverted back to using a for loop for the next step of the processing. The example below (which requires the library EGRET for pulling an example dataset) works, but probably can be replaced

Hi Eric, the following works for me.

Dear R-experts, this is not a direct R-problem but I hope you can help me anyway. I would like to minimize || PG-I || over P, where P is a p x p permutation matrix (obtained by permuting the rows and/or columns of the identity matrix), G is a given p x p matrix with full rank and I the identity matrix. ||.|| is the frobenius norm. Does anyone know an algorithm to solve such a problem? And if

Hi Everyone, My doubts are for Samba4.1 performance related enhancements (SMB2.1 / SMB3.0). My experimental samba server hardware is running 4.1 version. Want to improve robocopy WRITE throughput from a two samba client machines (win7 or win8 or server2012 x86 servers). Someone please advice me how can I use SMB2.1 or SMB3.0 capabilities to improve WRITE throughput. I tried samba4.1

Hi, I am a student at IIT Kanpur. I am working on Path Profiling, i just came with a need to know about the number of static paths in a program(actually in a function) before it's actually get run. As i saw in PathProfiling.c file in llvm\runtime\libprofile they are just storing the path information at run time and dynamically adding entries for the new path. But i need to know the number of

Hi, We are working on a project on forecast modeling and would like to know if there are any examples on how to READ/WRITE to a database (e.g. PostgreSQL) using R-Project. I do have a sample R Script which takes input as files from a directory and writes back output files to a directory. I would like to convert this script to read from a database and write back the output to a database.
