I'm looking for an R equivalent of Beaton's (1964) Sweep algorithim for partial inversion of a matrix by pivoting. It implemented in SAS/IML as sweep(matrix, indices), described here http://support.sas.com/documentation/cdl/en/imlug/59656/HTML/default/langref_sect266.htm and here for python http://adorio-research.org/wordpress/?p=262 -- Michael Friendly Email: friendly AT yorku

Hello, I have two plots on the same screen. I use the command par(mfrow=c(1,2)) in order to do this. When I try to make a legend for both plots, it only puts the legend in the plot on the right side. If I would like a legend that is outside of both of the plots, how would I do this? Thanks [[alternative HTML version deleted]]

Hello, Is there a way to get the Var-Cov matrix from the LMER function? Thanks [[alternative HTML version deleted]]

Hi, I would like to find a way to append data to an excel file through each iteration of a for loop. Is there a way to use a command such as write.table and append each iteration to a different sheet? Thanks [[alternative HTML version deleted]]

Hello, I am randomly generating values and then using an ANOVA table to find the mean square value. I would like to form a loop that extracts the mean square value from ANOVA in each iteration. Below is an example of what I am doing. a<-rnorm(10) b<-factor(c(1,1,2,2,3,3,4,4,5,5)) c<-factor(c(1,2,1,2,1,2,1,2,1,2)) mylm<-lm(a~b+c) anova(mylm) Since I would like to use a loop to

Hello, I use the command rnorm, and I feed these results into a lmer command. Since I am using the rnorm command I expect to get different results for each iteration, yet for each iteration I am getting the same answer. If someone understands why I am getting the same answer every time with a random number generator, I would appreciate help in understanding why this is happening. Is the lmer

Greetings, When I try to use the write.table command to save a matrix as a file and then open the file with read.table, if I try to take the mean of the entire matrix, instead each column of the matrix has its mean calculated. I have copied and pasted an example of my code below. When I try to make the header false with the read.table command, I am given an error message. I would appreciate any

my teachers doesnt understand R and I don't know how to use SAS. Anyone interested in translating my codes to test whether your SAS codes are as good as R??? I can test it on SAS codes once you have translated it .... regards:working: -- View this message in context: http://old.nabble.com/Translation-from-R-codes-to-SAS.-tp26486117p26486117.html Sent from the R help mailing list

To whom it may concern: Given that my sample size is n, my mean is 100, and my sd is 10, I need to use a random number generator (which I believe is the function rnorm(5,100,10)), but I need to repeat it a large number of times, and then plot the sampling distributions of the sample means, sd's, and variances of those generated sets. I'm having a real hard time trying to figure out how

Hi, I was wondering if function eigen() does something different from the function call eigen() in SAS. I'm in the process of translating a SAS code into a R code and the values of the eigenvectors and eigenvalues of a square matrix came out to be different from the values in SAS. I would also appreciate it if someone can explain the difference in simple terms. I'm pretty new to both

Dear List, I''m thinking about using xen productive in our datacenter, i''m still testing around with it. Now I got some questions, just for basic understanding, we got for example this environment: 2 Nodes 1 SCSI Pool server (Connected via scsi to both nodes) Now I want to build a "cluster" so i would like to make this: Node 1 -> Primary -| | --> domU

Hi All, I'm running rsync version 2.4.6 protocol version 24 on several Solaris 2.8 computers, and seversl RedHat Linux 7.2 computers. I have several character devices that I am rsyncing from my Solaris computer. Rsync works from one solaris to another solaris computer. But rsyncing these devices does not work from a solaris computer to the Linux computer. The devices are being copied over

Hi , We migrated to AD account in a Ubuntu 16.04 (Samba 4.3.11)and came across issues with user shares. Some of the users were able to access the shares and some were not. The server in question has both AD and File and we followed the samba wiki to enable the Windows ACL To migrate , we ran the following samba-tool domain classicupgrade --dbdir=/var/lib/samba.PDC/dbdir --realm=lin.GROUP

I thought R users might be interested (surprised) to hear that R will have some competition on Linux now.

If anyone wants to see a prime example of how inefficient it is to program in SAS, take a look at the SAS programs provided by the US Agency for Healthcare Research and Quality for risk adjusting and reporting for hospital outcomes at http://www.qualityindicators.ahrq.gov/software.htm . The PSSASP3.SAS program is a prime example. Look at how you do a vector product in the SAS macro

Good morning, I use SAS and R/S-Plus as my primary tools so I have a lot of experience with these programs. By far and away, SAS is superior for handling the "messy" datasets, but also the very large ones. I work at times with datasets in the hundreds of thousands (and on occasion, millions) of records. SAS, and especially PROC SQL, are invaluable for this. But once I get to
