Hi, I've been trying to use the set_callerid function in the AGI. It sets the CallerIDname properly but I can't figure out how to set the CallerIDnumber. Is it at at possible ? Cheers. SL

Dear R-ians, I want to perform an linear unmixing of image pixels in fractions of pure endmembers. Therefore I need to perform a constrained linear least-squares problem that looks like : min || Cx - d || ? where sum(x) = 1. I have a 3x3 matrix C, containing the values for endmembers and I have a 3x1 column vector d (for every pixel in the image). In theory my x values should all be in the

Dear RSYNCians, I'm trying to rsync my labtop pc (let's assume A-computer) with my desktop pc (let's assume C-computer) through our firewall. In between there is one computer (let's assume B-computer) that has an open port, so I theoretically could connect via a tunnel. I checked the SSH- website and internet and so on but did not find an answer that works. I tried the

Dear, I am looking for the simplification of a formula to improve the calculation speed of my program. Therefore I want to simplify the following formula: H = sum{i=0..n-1 , [ sum {j=0..m-1 , sqrt ( (Ai - Bj)^2 + (Ci - Dj)^2) } ] } where: A, C = two vectors (with numerical data) of length n B, D = two vectors (with numerical data) of length m sqrt = square root Ai = element of A with index

Dear, I'm trying to put up a scripts to synchronize my computers (HOST_A and HOST_C). I can connect both via HOST_B to avoid the firewall. I am trying to work with the rsync daemon to avoid hanging. I tried to figure out the mailinglist + FAQ, how to do it, but it seems I misunderstand something, since all your previous help did not work for me. I get the following error when executing

Dear Rsyncians, I'm trying to Rsync my windowsXP-pc A and C. There is a firewall in between A and C, but we have a port open on a linux-machine B to access C from A (and vica versa) via B. When I now run my Rsync scripts in cygwin: # _______________________________________________________________________________ #!/bin/bash # Command to synchronize (only update) two computers based on

Dear R-ians, I have a question concerning plotting different plots on one figure. I have written a script to plot an image, a legend (based on different rectangles) and a timeseries plot on one figure. In my R-lagnuage it looks like this (without arguments that are not usefull for my question): #---> I first define the functions image.data<-function(...){ .... #-->Plot the

Dear R-ians, I'm looking for a computational simplified formula to calculate a measure for heterogeneity (let's say H ): H = sqrt [ (Si (Sj (Xi - Xj)?? ) ) /n ] where: sqrt = square root Si = summation over i (= 0 to n) Sj = summation over j (= 0 to n) Xi = element of X with index i Xj = element of X with index j I can simplify the formula to: H = sqrt [ ( 2 * n * Si (Xi) - 2 Si (Sj

Dear R-ians, I am looking for the simplification of a formula to improve the calculation speed of my program. Therefore I want to simplify the following formula: H = Si (Sj ( sqrt [ (Ai - Aj)?? + (Bi - Bj)?? ] ) ) where: A, B = two vectors (with numerical data) of length n sqrt = square root Si = summation over i (= 0 to n) Sj = summation over j (= 0 to n) Ai = element of A with index i Aj
