Dear R-helpers, I'm trying to develop a function which specifies all possible expressions that can be formed using a certain number of variables. For example, with three variables A, B and C we can have - presence/absence of A; B and C - presence/absence of combinations of two of them - presence/absence of all three A B C 1 0 2 1 3 0 4 1 5 0 6 1

Dear R Users, Is it possible to make file names dependent on a changing variable? For instance. I generate random numbers in a loop and at each iteration I want data to write to file (I do not want to write everything in one file using 'append'): for (i in 1:50){ x<-matrix(runif(100, min=0,max=1),nrow=5,ncol=20) Write(t(x),file="Data_i.txt",ncolumns=5,sep="\t") }

Dear all, I have a 10 columns matrix which has 2^10=1024 unique rows, with values 0 and 1. What I would like to do is a little complicated; in a simple statement, for a subset (say 1000 rows) I want to perform pairwise comparisons between all rows, find out which rows differ by only one value, replace that value by "x", get rid of the comparisons that differ by more than one value

Dear Sir or Madam: This is an extension to a earlier post, about looping through several thousand files, and testing student's models against a different data-set, called rclnow, for "recall now". The problem is, that the instructor never specified to the students, what they should name their "lm" object. So what they created was: "arbitrary variable name"

Hi I used write() the other day to save some results. It seems that write() does not record the full precision of the objects being written: > write(pi,file="~/f",ncolumns=1) > pi.saved <- scan("~/f") Read 1 item > dput(pi) 3.14159265358979 > dput(pi.saved) 3.141593 > pi-pi.saved [1] -3.464102e-07 > This difficulty was particularly difficult to

Hi list, is it possible to add multiple homedir templates to smb.conf ? I have a running linuxsystem where homefilesets are mounted from different windows-servers to subdirs like: /home/server01/home/USERNAME /home/server02/home/USERNAME /home/server03/home/USERNAME The users come via winbind. In the smb.conf the entry for the homedir: template homedir = /home/%U So how is it possible to

Hi I wrotte this function but when I get the "tmp.xls" file it shows data in a rare way. I mean not appears a matrix with 2000 rows and 100 columns. Can anyone help me, guide me? kim<-function(){ tmp<-randz<-matrix(rnorm(200000, mean=0,sd=0.01 ),2000,100); dim(tmp) write(tmp,file="tmp.xls") Thanks in advance. On the other hand, everytime I execute a function

Readers, Scenario: data x consists of one column; 1 2 3 data y; 4 5 6 Is it possible to write to file such that the file is: 1,4 2,5 3,6 using the write.file function? I have tried the command: write(x,file="file.csv",ncolumns=1,append=TRUE,sep=",") write(y,file="file.csv",ncolumns=1,append=TRUE,sep=",") but the result is: 1 2 3 4 5 6 yours,

Hi, I need to resample characters from a dataset that consists of an extremely long string that is written over hundreds of thousands of lines, each of length 50 characters. I am currently doing this by first inserting a space after each character in the dataset and then using the following commands: y <- as.matrix(read.table("data.txt"), stringsAsFactors=FALSE) bstrap <-

i have a function that returns a list containing a variety of variable types i am trying to run the function multiple times and return the output into a variable with a semi-consistent naming pattern i.e., for ten trials i want to return the list into variables trial1,trial2,...trial10 is there a generic way to get this to happen i have a similar process that does the same thing to an external

Is there any way to run an R script without running R? As an example, suppose I have a tcl/tk interface that asks for a number (in a GUI) and displays its factorial. Is there a way to invoke this script without invoking R? I'm using R 2.4.1 in GNU/Linux Fedora Core 4. Alberto Monteiro

Dear users, I want to transfer a list of results from R to some practical format, from where I can continue manipulating, copying,... the values, e.g. : list1 <- list("My first list", matrix(1:6, ncol=3), c(1,2,3,4,5,6) ) # Imagining I forgot something and want to add it to the list like: list1[[4]] <- list(c(4,4,4), "This is it") # Now I want to transfer the list to

Some languages (e.g. German and Danish) have special letters that are often written using two-letter combinations when the appropriate keyboard or medium is not available: ? = ae ? = ue ? = oe ? = ae ? = oe ? = aa ? = ss (there are undoubtedly far more examples than those) As a user of an index, I would like to be able to search for e.g. "schaefer" and get matches on both

Dear all, I am trying to replicate some multilevel models with binary outcomes using R's "lmer" and "glmmPQL" and Stata's gllmm, respectively. The data can be found at <http://www.uni-koeln.de/~ahf34/xerop.dta>. The relevant Stata output can be found at <http://www.uni- koeln.de/~ahf34/stataoutput.txt>. First, you will find the unconditional model,

I am looking for some guidance on converting a large MySQL database to Xapian. The current structure is that the database is broken up into 160 "sub-databases". There are 50,000 or so records in each stub database. Each record has content that I am full-text indexing. The average size of the text is about 59k characters. The database is broken up into sub-databases because the MySQL

The native authentication methods of openssh are (not counting insecure RhostsRSAAuthentication) 1) public key 2) password For users with home dirs in AFS space, method 1) does not work. Except with (non foolproof) fiddling on the access controls within the home directory. This might lead to security issues when done by inexperienced users. Without some work, only 2) remains.
