V1,V2,V3 15,10,4 6,4,7 10,5,2 8,6,6 This does the work. However, I fear that you are going to use it on 100 variables, and I would strongly advice againts searching for linear relations that way. Dieter x=read.table("sample.txt",header=T,sep=",") nm = names(x) for (i in 1:2) { for(j in (i+1):3) # note that you need the ()! { formula= as.formula(paste(nm[i],"~",nm[j],sep="")) slr=lm(formula, data=x) smr=summary(slr) print(smr) } } ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
