Does "sink" stand for anything?
Hello Everyone,   Learning about R and its wonderful array of functions. If it's not obvious, I usually try to find out what a function stands for. I think this helps me remember better.   One function that has me stumped is "sink." Can anyone tell me if this stands for something?   Thanks,   Paul         __________________________________________________ [[alternative HTML

compilers a security risk?
I manage a web hosting server that we've recently upgraded, in part so we could accommodate a domain that will enable community mapping. In a recent exchange of mails one developer said: "I could build the package directly on the server machine you have, provided that the potential security risk posed by having compilers installed is not an issue." and another said:

Allocate virtual memory on hard drive
Dear All, I have a long sequence and want to find the quantile, or sort it first. It seems sort() or quantile() reaches the memory limit. Is there a way to allocate more memoy on SSD for R when startup, so that R can use both RAM and hard drive space? Thank you. Best wishes, Jie

R 64-bit Windows isn't using much memory
I have a 9 GB RAM Windows Vista machine. I installed the 64-bit version of R 2.11.1 for Windows from here: http://cran.r-project.org/bin/windows64/base/ I am running a program now in R. However, looking at Windows Task Manager, I see that Rgui.exe is only using 12% of CPU and 191,900K of memory. How do I max it out? I know the default memory limit is the amount of installed RAM, but it

I will start by listing what I found so far, and then go on asking for help. So far I found the a manual by Xianhong Xie from Rnews_2005-2 (see page

[LLVMdev] memory scopes in atomic instructions

Here's the plain text (I hope!): Hi all, OpenCL 2.0 introduced the notion of memory scope in atomic operations to global memory. These scopes are a hint to the underlying platform to optimize how synchronization is achieved. HSAIL

Matrix scalar operation that saves memory?
One possibility might be to use Rcpp. An R matrix is stored in contiguous memory, which can be considered as a vector. Define a C++ function which operates on a vector in place, as in the following: library(Rcpp) cppFunction( 'void subtractConst(NumericVector x, double c) { for ( int i = 0; i < x.size(); ++i) x[i] = x[i] - c; }') Try this function out on a matrix.

As you know, the Linux version of syslinux supports mount points. But for the Win32 version, it only supports drive letters as in: syslinux ?ma e: However, drive letters are not always available, such as drives mounted to NTFS folders. In order to install syslinux to these drives, future release of syslinux should support using mount points as the drive spec; or alternatively, support disk

Adressing multiple cores (CPUs)
Dear all, I'm sitting here just in front of my new PC@work and wonder about the following question: * How can I adress multiple CPUs (cores) out of R to speed up the simulations I run? * What are the prerequisites to do so? Maybe anyone could give me a hint where to start reading? Regards, Thomas P.S.: I searched the R-archive to find an answer but did find none.

Preparing for multi-core CPUs and parallel processing applications
Hello I am fortunate (or in really big trouble) in that the research group I work with will soon be receiving several high end dual quad core machines. We will use the Ubuntu OS on these. We intend to use this cluster for some extensive modeling applications. Our programming guru has demonstrated the ability to link much simpler machines to share CPUs and we purchased the new ones to take
