Balancing ip traffic over two or more internet (adsl) connections
Hi. I''ve got here the following configuration: (turn on fixed pitch font to be able to see the scheme in a more accurately way) Client machines <-----> ADSL Router 1 <-----> INTERNET (192.168.0.0/24) (192.168.0.229) NAT Client machines <-----> ADSL Router 1 <-----> INTERNET (192.168.1.0/24) (192.168.1.229) NAT [if doesn''t really

PDC, BDC and member server
Hi all! I want to implement a samba architecture with one PDC one BDC and 1 file server acting as a domain member server in a lan with approximately 60 clients. Even if they are not so many I need a solution that can give scalability to 100 clients in near future and reliability in case of hardware fail. Therefore I'm going to configure this system in order to obtain redundancy in user

Chi square convolution?
Hi, I want to determine the confidence interval on the sum of two sigma's. Is there an easy way to do this in R? I guess I have to use some sort of chisquare convolution algorithm??? Thanx, Roy -- The information contained in this communication and any atta...{{dropped}}

convolution bug (PR#408)
Full_Name: Bill Simpson Version: 65.1 , 0.90.1 OS: Linux Submission from: (NULL) (193.62.250.209) I reported this on r-help, but here is official bug report. The present convolve() does not do convolution by default. Its default behaviour is correlation. This is a bug. The default argument conj should be set to FALSE. The zero-padding should be on the right for linear convolution (don't

2D convolution
Dear all, I have an image that I need to filter, and so I'm looking for a method to convolve it with a matrix. If I understood the docs for convolve correctly, it only works in 1D (and I have tried to convolve, it didn't look good). So, I wondered if anybody have implemented 2D convolution in R, or have any good advices to share (beyond having a look at mvfft), before I go hacking?

2D Convolution Function
Dear R-Helpers, I want to try the 2D (two-dimensional) convolution in R. For example, let us we have the following kernel and data. kernel <- (1,2,3,2,1) data <- array(1:100, dim=c(10,10)) I know the function 'convolve' only for one-dimensional convolution, but it is just for a 1D sequence. Is there any function for 2D convolution? For theory, please refer to the following link:

Convolution confusion:
Hi, I'm new to R, and I'm a bit confused with the "convolve()" function. If I do: x<-c(1, 2, 3) convolve(x, rev(x), TRUE, "open") = 9 12 10 4 1 But I expected: 3 8 14 8 3 (like in Octave/MATLAB - conv(x, reverse(x)) ) 3 2 1 x 1 2 3 = 3 2 1 0 6 4 2 0 0 9 6 3 = 3 8 14 8 3 The thing is, that "convolve(x, x, TRUE, "open")" works. For me

Convolution vector to be derived
I want to generate the following outcome using convolution of two sequences. x <- c(1,2,3,4,5) y <- c(6,7,8,9) The resulting convolution vector is 6 19 40 70 100 94 76 45 When using convolve(), it is hard to produce the result above. Would you help me out to get that? Best regards Moohwan Kim

solution of convolution equation
Hello, May be somebody can help me... I am trying to find a solution of a convolution equation using fft (and unfortunately I do not have a good background for this). So I am just trying to figure out how it can be implemented in R. I have two multidimensional independent variables X and Z and I know their densities fx and fz, which are multidimensional arrays. So I have to find the density of

convolution of the double exponential distribution
Is there any R function that computes the convolution of the double exponential distribution? If not, is there a good way to integrate ((q+x)^n)*exp(-2x) over x from 0 to Inf for any value of q and for any positive integer n? I need to perform the integration within a function with q and n as arguments. The function integrate() is giving me this message: "evaluation of function gave a

Producing different text formats in R
Dear all, I am facing a strange problem with text files formats. I am currently using a C++ code named voro++ (http://math.lbl.gov/voro++/). This code accepts text files with four columns: <id> <x> <y> <z> where id is an identification number and x,y,z are the coordinates of a point in a 3D space. The input file, name it myfile_cpp.txt, is generated by another C++ code

Convolutional neural networks (CNN) - build a model and After?
Hi, I am learning CNN using MXNet R package. I am following this great tutorial about olivetti_faces reconnaissance <https://www.r-bloggers.com/image-recognition-tutorial-in-r-using-deep-convolutional-neural-networks-mxnet-package/>. In the end after building model and testing the final score was 0.975. It is great score but what can do after with this model? How can use this model for
