how to generalize the arguments for lm() (r-help@lists.R-project.org)
you can just use a design matrix on the right hand side of 'formula', e.g., factors <- matrix(rnorm(100*10), 100, 10) y <- rnorm(100) lm(y ~ factors) I hope it helps. Best, Dimitris

Hello,
How could I generalize the following statement for an arbitrary number of columns instead of 7?
result[[i]]<-lm( returns[,i] ~ factors[,1] + factors[,2] + factors[,3] + factors[,4] + factors[,5] + factors[,6] + factors[,7] )
Thank you,
