similar to: speeding up a special product of three arrays

I was posed the following problem/teaser: given two matrices, come up with an "elegant" (=fast & short) function that returns a matrix with all and only the non-duplicated columns of both matrices; the column order does not matter. In essence, a matrix equivalent of union(x,y), where x and y are vectors. I could not come with anything nice. Any ideas? Giuseppe -- Giuseppe A.

I am trying to install the gls package (a wrapper for GNU scientific library special functions) package under Ubuntu 5.10. I have gls-bin (the debian GNU Scientific Library binary package). When I try to install the R package, I receive the following. > install.packages("gsl",dependencies=T) Warning in install.packages("gsl", dependencies = T) : argument

I have two questions for the group. One is very concrete, and is dangerously close to a "please do my homework" posting. The second follows from the first one but is more general. I would welcome the advice of experienced R users. As for the first one: I have a data frame with two variables X Y A, chris D, chris B, chris B, chris C, andrew E, andrew C, andrew B, beth

Dear list, I am a little puzzled by computing time in connection with calling C functions. With the function mysolve1 given below I solve Ax=B, where the actual matrix operation takes place in mysolve2. Doing this 5000 times takes 3.51 secs. However, if I move the actual matrix inversion part into mysolve1 (by uncommenting the two commented lines and skip the call to mysolve2) then the

Hi, I have 2 huge datasets - May and Jun - a miniscule sample of one is given below. I am trying to do 2 things with these datasets. I need to verify if the weighted average of variable A for a Reason in Jun is same/different from the same for May. To do this I am first computing the weighted average for each SubReason using a function I wrote. Where I need help is applying the function on both

Dear all I would like to have some data in the form of a 2-dimensional array (matrix) of lists, so that I can easily find the desired list object by indexing the structure by rows and columns. In matlab there exists a data type called "cell array": a matrix of "cells", which are composite objects very similar to R lists. I know that in R you can create 1-dimensional

Hi all, When I ran a script containing the following codes: png(paste(savepath,"a_rnaplot.png",sep = ""),width = fwidth, height = fheight,pointsize = fpointsize); data_deg <- AffyRNAdeg(data_cel) plotAffyRNAdeg(data_deg,col=cols,lty=1,lwd = "2") #a <- par("fin") legend("bottomright",sampleNames(data_cel),col=cols,lty=1)

I've got Zaphfc working running Asterisk v. 0.7.2 Then I have tried with Asterisk V. 1.0 and the latest from CVS - with no succes. Has anybody got zaphfc working with newer version than 0.7.2 ?

Hi! Has anybody seen anything like this using zaphfc? On outgoing calls (via isdn) , the line gets hung-up as soon as the called party answers. As seen below i get some protocol error (6) - but i'm not sure if this is related to the "hang-up" which apparently comes a little earlier?! Incomming calls on the isdn (zaphfc) interface is working just fine (P.S. what about the

Thanks Denis, I was looking for the option 'dns:x' in the wiki but I didn't find it. Now it works. I used    log level = 3 auth:3  dns:0 auth_audit:3 gives me unknown class message But where I can find a complete list of classes for log level? I'll also give a try on the last version of samba with json. Thanks again Giuseppe On 1/18/2018 4:52 PM, Denis Cardon wrote:

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, First, as far as I can tell, this topic hasn't been mentioned in the mailing lists in awhile (atleast not as far as google can tell). Is there any client/program that can send "net start" requests to windows boxes. The ability to start a program as a service on a windows box remotely would obviously be very handy. I am aware of

Hi, I'm working with the ks.test() function and I have also implemented the test using Conover as the reference. My D value matches that produced by R. However to calculate the p value I am using the code described in Numerical Recipes in C++ (2nd Ed.) pg 631. The p value produced by the NRC code is generally larger than that produced by R by a factor of 10. Currently I am not in a position

Hi, I want to free memory used by R. The usage of rm and gc give no result. I'm running an algorithm consuming a huge memory and I need to recover the memory used by R between 2 call of my algorithm. Thank you in advance for your help. e-mail: sofiane.lariani at rdls.nestle.com Sofiane Lariani
