Convergent Cross Mapping
Dear All, I am looking for an R implementation of the convergent cross mapping method (see http://bit.ly/XN8OZX and http://www.uvm.edu/~cdanfort/csc-reading-group/sugihara-causality-science-2012.pdf ) The method is presented as an improvement over Granger causality ( http://bit.ly/XN8ydi ), but its implementation (involving shadows of multidimensional manifolds) must be quite some work...

[BUG] imap-login segfault when running nmap -sV
Hi, I've noticed that nmap crashes my imap-login (also pop3-login) and narrowed it down to `nmap -sV -p 993 $host`. I've noticed that if I remove "ssl_protocols = !SSLv2 !SSLv3" from my config or enable SSLv3 rather than disabling it the segfault disappears. I'm running on Arch Linux with dovecot 2.2.16-1 and openssl 1.0.2.a-1. I've also attached a network capture, but

[RFC PATCH 0/9] vhost-nvme: new qemu nvme backend using nvme target
Hi, This is the first attempt to add a new qemu nvme backend using in-kernel nvme target. Most code are ported from qemu-nvme and also borrow code from Hannes Reinecke's rts-megasas. It's similar as vhost-scsi, but doesn't use virtio. The advantage is guest can run unmodified NVMe driver. So guest can be any OS that has a NVMe driver. The goal is to get as good performance as

[PATCH 28/28] nvme-pci: use dma_alloc_pages backed dmapools
Switch from coherent DMA pools to those backed by dma_alloc_pages. This helps device with non-coherent DMA to avoid host accesses to uncached memory for every submission of a larger than single entry I/O.

lme: extract variance estimate
For a Monte Carlo study I need to extract from an lme model the estimated standard deviation of a random effect and store it in a vector. If I do a print() or summary() on the model, the number I need is displayed in the Console [it's the 0.1590195 in the output below] >print(fit) >Linear mixed-effects model fit by maximum likelihood > Data: datag2 > Log-likelihood:

Matrix efficiency in 1.9.0 vs 1.8.1
I'm seeking some advice on effectively using the new Matrix library in R1.9.0 for operations with large dense matrices. I'm working on integral operator models (implemented numerically via matrix operations) and except for the way entries are generated, the examples below really are representative of my problem sizes. My main concern is speed of large dense matrix multiplication. In R

panel ordering in nlme and augPred plots
Hi, I'm new at this, I'm very confused, and I think I'm missing something important here. In our pet example we have this: > fm <- lme(Orthodont) > plot(Orthodont) > plot(augPred(fm, level = 0:1)) which gives us a trellis plot with the females above the males, starting with "F03", "F04", "F11", "F06", etc. I thought the point of

Simplex Density Plots
Hello, I have just started using R, and have found it quite easy to make plots of probability densities for normal and beta distributions, etc. Now, I'm looking at trying to make a simplex plot of a Dirichlet density, but have gotten stuck and was hoping that someone could help. Ideally, the plot would look something like the 3d plots on Wikipedia here:

Manipulate solution of simplex
Hi, I need some help. I'm doing a project that demands me to obtain several simplex solutions and I would like to can keep the solution in a vector or something to be able to use it after I get it. The comand simplex() prints the solution but how can I keep it? Another alternative would be to export it to excel, how can I do this? I just see the solution and have to note it on a paper or

Simplex "Out of Bounds" Error
I am running the following code (testing the use of the simplex function to determine if a point is in the convex hull of another set of points or not): >a <- c(0, 0) >A3 <-matrix(c(1,2,3,4,1,1), ncol = 2, byrow = T) >b3 <-c(1.5, 3.5, 1) >simplex(a = a, A3 = A3, b3 = b3) and the following error message appears: Error in simplex1(out1$a[1:(n + m1 + m2)], out1$A[, 1:(n + m1

Simplex(boot) returning invalid answer
In trying to use simplex() from the boot package, I have run into a situation that doesn't seem like it should be possible. It is claiming that it has solved the LP, but returns a vector of all zeros, which does not satisfy the constraints I passed in. A small example: > ubMatrix <- matrix(c(1,1,-1,0,-1,-1), 3, 2) > ubVector <- c(2,1,-1) > objective <- c(0,1) >

wordcloud y tabla de palabras
Buenas noches grupo. Saludos cordiales. He seguido en la búsqueda de una forma que me permita realizar la comparación de dos documentos pertenecientes a los años 2005 y 2013, y que pueda representar finalmente con wordcloud y con una table en la que las columnas sean los años de cada informe "2005" y "2013", y las filas sean las palabras con la frecuencia de cada una de ellas

n.iter in simplex()
Dear R users, Is anyone familiar with the "n.iter" argument of the simplex() function (in the boot package)? It seems it doesn't have an effect no matter what value I set it ... I'm trying to solve a linear programming problem and running into the problem of simplex.object$solved = 0 or "A value of 0 indicates that the maximum number of iterations was reached without
