Hi, You could try: A<- matrix(unlist(read.table(text=" 1 2 3 4 5 6 7 8 9 9 8 7 6 5 4 3 2 1 ",sep="",header=FALSE)),ncol=3,byrow=FALSE,dimnames=NULL) library(matrixStats) ?res1<-t(sapply(split(as.data.frame(A),as.numeric(gl(nrow(A),2,6))),colProds)) ?res1 #? [,1] [,2] [,3] #1??? 4?? 10?? 18 #2?? 63?? 64?? 63 #3?? 18?? 10??? 4

Dear all, I have a big problem: - I got two matrices, A and B - A shows identifies the value of B, however the values of B must be summed - For instance, 1 1 2 2 2 2 1 1 gives matrix a 3 4 2 1 1 1 2 2 gives matrix b Now the result for the value 1 would be 7 4 which are the rowsums of the values of matrix B given that matrix A has the value 1. How can I do this automatically? I

Hi Folks, What is the best way to avoid a function being read in anew (and masking an exiting function) when a definition of it has already been established in R? Reason: Fernando Tusell and I are working up Schafer's 'CAT' for R (basically done now, just needs some cosmetic tidying up). This uses a function 'slice.index', present in S but not in the versions of R we were

Dear all, Our department uses the linux system and we are not allowed to submit job directly. We must make a batch to submit through "qmon". so, I make a foo.sh file, which only contains one line: nohup R --vanilla < foo.txt > foo.results foo is all my codes. It is a simulation of 200 times. I set the seed at the beginning. It is to estimate the success probability, which is

I'm still not fully understanding exactly how R is handling data frames, but am getting closer. Any help with this one will likely go a long way in getting me there. Let's say I have a data frame, let's call it "a". Within that data frame i have two variables, let's call them "b" and "c", where "b" is a single numeric value per observation,

Hello Samba List, I am trying to figure the best way to move forward with bringing a Samba setup up to date. We currently have a Samba DC running version 3.5.21. This is running on an old Red Hat Enterprise Linux 4 box. There are about 20 users in the domain, a couple of groups, and about 10 shares. About 20 Windows 7 PCs are joined to the domain. We?d like to end up with a Samba

Is there a way to make rsync unconditionally transfer files, i.e. create them anew even if the target already exists and is identical to the source ? rsync -I looks closer but still avoids transferring the files. -- Andr? Majorel http://www.teaser.fr/~amajorel/

Hello, I do have two different time series A and B, they are different in length and starting point. A starts in Jan, 2012 and ends in Dec, 2012 and B starts in March, 2012 and ends in Nov, 2012. How can I plot those two series A and B in the same plot? I.E., from Jan. 2012 - Feb, 2012, it would have one data point from A and from Mar, 2012-Nov, 2012, it would have two data points from A and B,

Hello to everyone on the list. I want to contribute to the Wiki, to the "Tips and Tricks" section, "Installation" part thereof, on the topic of "Installing CentOS anew to ext4 partition(s)". My wikiuser name is AlexeyAsemov. Overall contents of the T&T article can be found in my #9 post here:

Am I correct in reading the code that there is no "noht" (turn off hyperthreading) option in Xen (except in powerpc)? This was a surprise to me as I've seen it documented in various places and I recently suggested it as a diagnostic to a customer. =================================== If Xen could save time in a bottle / then clocks wouldn't virtually skew / It would save every

The title says it all. Does anyone know of a way to save your packages when you upgrade to a new version of R? This may seem petty, but I'm accumulating enough packages that having to download and install each of them anew every time I install a new version of R is rather of a pain. Ideally, I would like the new version of R to recognize the packages I've installed on the

I am building a new system using an Kingston 240GB SSD drive I pulled from my notebook (when I had to upgrade to a 500GB SSD drive). Centos install went fine and ran for a couple days then got errors on the console. Here is an example: [168176.995064] sd 0:0:0:0: [sda] tag#14 FAILED Result: hostbyte=DID_BAD_TARGET driverbyte=DRIVER_OK [168177.004050] sd 0:0:0:0: [sda] tag#14 CDB: Read(10)

Well, I followed this link: http://www.mikerubel.org/computers/rsync_snapshots/ and implemented it (with a bit of tweaking) on my home network. It is used to make snapshots of two Windows PC's over samba. On one of the machines (and not the other, from what I can tell) it deletes files from the target machine for no good reason (ie. they still exist on the source machine). Then, if I run

Is there a good, foolproof dovecot-openldap tutorial that walks you through the steps and works with the newest version of both softwares?

Sorry to hop on an existing conversation but this seemed like a good point to jump in with this question. Say I have a service account, with a random password that is set to never expire. What component is expected to periodically renew (or request anew) the Kerberos TGT using that password? I see lots of information about SSSD handling this, but less so with Samba. Also, I understand that in

Hi, I am working on using LLVM to compile parts of longrunning PostgreSQL queries into native code for faster code execution. As postgres is, nearly, entirely written in C and has long-lived (5 years) supported branches (making the higher API stability important), I'm currently using the C API. I started out using MCJIT but it looks like that's slowly on the way out. My current concern

Somehow during the process of updating both Ubuntu and R to the latest versions I ended up with a version of R 3.5 installed into the sudo user's home directory with default libraries set to the sudo user home directory as well (/home/uname/R/x86_64-pc-linux-gnu-library/3.5 rather than usr/local/lib/R/site-library). I've tried to remove using sudo apt purge r-base r-base-dev and get a

Here's another interesting problem: if you recall I have a data frame (LCvars1) that consists of about 1500 cases (rows) of data from kids who took a test of listening comprehension. The columns are their scores (1 = correct, 0 = incorrect, . = missing) on 140 test items. The items are numbered sequentially and are ordered by increasing difficulty as you go from left to right across the
