horizontal direct product
...e gauss code into R, and gauss has a matrix product function called the horizontal direct product (*~), which is some sort of variant on the Kronecker product. For example if x is 2x2 and y is 2x2 the horizontal direct product, z, of x and y is defined (in the Gauss manual) as: row 1 = x11*y11 x11*y12 x12*y11 x12*y12 row 2 = x21*y21 x21*y22 x22*y21 x22*y22 Or in R code if: x <- matrix(seq(1,4,by=1),2,2, byrow=TRUE) y <- matrix(seq(5,8,by=1),2,2, byrow=TRUE) The resulting matrix, if I had an operator, would be the following matrix z, here formed in a contrived manner: z.1 <...

Manipulation of data.frame into an array
Hello everyone, I want to transform a data.frame into an array (lets call it mydata), where: mydata[[1]] is the first imputed dataset...and for each mydata[[d]], the first p columns are covariates X, and the last one is the outcome Y. Lets assume a simple data.frame: Imputed = data.frame( X1 = c(1,2,1,2,1,2,1,2, 1,2,1,2,1,2,1,2), X2 =

Writing a workable function
After searching in R- Introduction, FAQ, help... I don't understand this: I write a function in a file (.R): tt <- function(mc) { date() mc<-read.csv2("machines.txt",na.strings="") date() } I source it in R and I type tt(). The answer is > tt() [1] "Mon Aug 14 11:18:25 2000" > The instructions following the first "date()" are ignored. Why?

Dovecot Maildir ownership/permission problem
Hi, I have successfully configured Dovecot+Postfix+SSL/TSL and it seems that everything is working except that I have a permission problem with the items under Maildir. When a mail is first delivered into a user, Postfix automatically creates the Maildir using the user's account and group. It is readable only by the user. This seems to be the correct setting for me, as only the user
