I'm looking for an R equivalent of Beaton's (1964) Sweep algorithim for partial inversion of a matrix by pivoting. It implemented in SAS/IML as sweep(matrix, indices), described here http://support.sas.com/documentation/cdl/en/imlug/59656/HTML/default/langref_sect266.htm and here for python http://adorio-research.org/wordpress/?p=262 -- Michael Friendly Email: friendly AT yorku

As multi-queue nics were commonly used for high-end servers, current single queue based tap can not satisfy the requirement of scaling guest network performance as the numbers of vcpus increase. So the following series implements multiple queue support in tun/tap. In order to take advantages of this, a multi-queue capable driver and qemu were also needed. I just rebase the latest version of

Hello, everyone I run Eclipse Ganymede and R 2.7.2 at work.

Hello guys.I am working on implementing the PL2 weighting scheme of the DFR framework by Gianni Amati. It uses the Poisson approximation of the Binomial as the probabilistic model (P), the Laplace law of succession to calculate the after effect of sampling or the risk gain (L) and within document frequency normalization H2(2) (as proposed by Amati in his PHD thesis). The formula for w(t,d) in
