yet another vectorization question
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

millions of comparisons, speed wanted
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

write() gotcha
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

Extracting an object name?
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"

change the name of file
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") }

R-alpha: Re: Pretest Version + Notes --- write.table
Kurt writes KH>> * I am also not sure whether one should include the write.table() KH>> function I posted some time ago. It seems to be a bad idea to make a KH>> contrib package out of it (containing only a single function ...). Yes, I think we should have a good "write" function for data.frames. However, I would go even further and 'vote' for a GENERIC
