This is great. Thank you for your help, but let me make sure I fully understand. Here is the looping file I use to subset the data frame, create a tex file, and Sweave it. This results in N number of tex files where N is equal to the number of rows in the data frame. list <- unique(wide$stuid) master = "master.tex" for (i in list){ tmp1 <- subset(wide, stuid==i) tmp2 <- paste(i, "tex", sep=".") Sweave("fam_template.Rnw", output=tmp2) file.append("fam_master.tex", tmp2) } If I follow correctly, I would need to...

Hello everyone, the time for me to use a OpenLDAP server is getting closer ( :( yikes..I'm still scared sorta) , I currently have a Samba PDC with tdbsam with 50 users goes fine, our company will grow (doing our best) in this year by a minimum of 25-30 computers, and I've stuided the TOSHARG , and it says that for every 50 computer a bdc is suggested. The questions : 1.how does the client who is logging in to the domain know which server to use pdc bdc1 bdc2 ? , how is this decided. 2.is it a good idea to place the pdc and bdc close to each other , on the same swit...

hi, I am still batteling with winbind, and frankly, i am getting desperate enough to long for a weekend without any computers in sight (that is bad for an addict) I know I probably make a small stuid blunder but still, I cant find it. The attachment is my smb.conf file. I created the needed paths, I even made sure the ermissions are set! I created asmbusers file with contains the following line: root = Administrator admin Then I added a user root to the smbpasswd file smbpasswd -a root pass...

Dear List: I am encountering an error that I can't resolve. I'm looping through rows of a dataframe to generate individual tex files using Sweave. At random points along the way, I encounter the following error Error in file() : cannot find unused tempfile name At which point Sweave halts. There isn't a logical pattern that I can identify in terms of why the program stops at

Dear List: I am working to construct a matrix of a particular form. For the most part, developing the matrix is simple and is built as follows: vl.mat<-matrix(c(0,0,0,0,0,64,0,0,0,0,64,0,0,0,0,64),nc=4) Now to expand this matrix to be block-diagonal, I do the following: sample.size <- 100 # number of individual students I<- diag(sample.size) bd.mat<-kronecker(I,vl.mat) This
